Repairing a Laptop Battery Laptop batteries are made of battery cells and a circuit board. The typical has several hundred charge cycles, so once these are exhausted the cells no longer hold a charge. If this is the case with one's laptop battery, the easiest way to repair it is to replace the cells.

Are available for purchase at a fraction of the cost of buying a new battery. However, it is best to have some prior experience working with electronics to avoid headaches and wasting money on battery cells and any related supplies. Removing the Battery To ensure safety when repairing a laptop battery, one must make sure to take all necessary precautions. The first step is to make sure the current laptop battery drained completely of power before removing it.

Toshiba Battery Replacement Program. Toshiba sold the affected battery packs with new laptops and as accessories or replacement battery packs in the course of repair.

Once the power drains completely, buyers need to double check the laptop is off before removing the battery. Opening the Battery In order to replace the battery cells, open the battery case itself. To accomplish this, carefully pry open the case with a flat-edge screwdriver and.

Once the battery case is open, buyers are able to analyze the type of battery cells needed and what kind of soldering has to be done to install them. A good tip is to take a photo or draw a diagram of the setup to remember where everything goes.

If the cells and battery case do not properly fit back into the laptop, the repair is in vain, so it is important for users to take extra to prevent the case from warping when it is being opened. Replacing the Cells It is important to use a to make sure the old cells fully discharge before removing them to prevent an electrical shock. Using a, remove the current cells from the wires before removal. To find the proper replacement cells, use the model number on the battery pack. Solder the new cells to the wires, making sure to connect them to the appropriate wires.

Soldering is the best way to ensure a proper connection. If replacing Lithium-ion cells, use and handle with caution since they are capable of exploding. Once the battery case is close and installed back into the laptop, the batteries need to charge completely before using the laptop.

Smart Batteries Some laptop batteries require a continuous power source to protect vital data in the memory. When replacing cells in these types of batteries, one needs to provide secondary voltage by connecting a before removing the old cells. Only with the installation of new cells can the user remove the resistor. Other Tips to Keep in Mind. Only use battery cells of the same state-of-charge (within ten percent of each other).

Do not use cells with different chemistry, age, or capacity (i.e. Do not use nickel cells if it uses lithium cells). Insert lithium cells with correct polarity since they are sensitive to reverse polarity. When charging, discharging, or repairing a lithium cell battery, use a protection circuit. Use a to disrupt current on high heat.

When soldering, limit heat transfer to battery cells to avoid heat buildup How to Buy Laptop Battery Repair Supplies Buyers can find all the supplies they need to repair their laptop battery on by searching using key phrases, such as '.' You then can narrow down the results by clicking on any of the relevant filters located in the sidebar. It is advisable to shop from Top Rated sellers and to carefully review all product descriptions to make sure you are buying the appropriate item.

BU-911: How to Repair a Laptop Battery Find out the challenges and limitations of repairing “smart” batteries Most laptop batteries are smart and consist of the “chemical battery” that is managed by the “digital battery.” A common protocol is the System Management Bus, better known as. The typical SMBus battery has five or more battery connections consisting of positive and negative battery terminals, thermistor, clock and data. The connections are often unmarked; however, the positive and negative are commonly located at the outer edges of the connector and the inner contacts accommodate the clock and data. (The one-wire system combines clock and data.) For safety reasons, a separate thermistor wire is brought to the outside. Figure 1 illustrates a battery with six connections. Figure 1: Terminal connection of a typical laptop battery The positive and negative terminals are usually placed on the outside; no norm exists on the arrangement of the other contacts.

Courtesy of Cadex Some batteries are equipped with a solid-state switch that is normally in the “off” position and no voltage is present at the battery terminals. Connecting the switch terminal to ground or pulling it up often turns the battery on.

If this does not work, the pack may need a code for activation. Battery manufacturers keep these proprietary codes a well-guarded secret to which even service personnel have no access. Use a voltmeter to locate the positive and negative battery terminals and establish the polarity. If no voltage is present, a solid-state switch may be in the “off” position and needs activating. Connect the voltmeter to the outer terminals, take a 100-Ohm resistor (other values may also work), tie one end to ground and with the other end touch each terminal while observing the voltmeter. Repeat by tying the resistor to a positive voltage potential.

How To Open Toshiba Laptop Battery

If there is no response, then it is possible that the battery is dead or locked by a code. The 100-Ohm resistor is low enough to engage a digital circuit and high enough to protect the battery against a possible electrical short. Establishing the connection to the battery terminals should now enable charging.

If the charge current stops after 30 seconds, an activation code may be required. Some battery manufacturers add an end-of-battery-life switch that turns the battery off when reaching a certain age or cycle count. They argue that customer satisfaction and safety can only be guaranteed by regularly replacing the battery. Mind you, such a policy also rotates inventory. If at all possible, connect the thermistor during charging and discharging to protect the battery against possible overheating. Use an ohmmeter to locate the internal thermistor. The most common thermistors are 10 Kilo Ohm NTC, which reads 10kΩ at 20C (68F).

NTC stands for negative temperature coefficient, meaning that the resistance decreases with rising temperature. In comparison, a positive temperature coefficient (PTC) causes the resistance to increase. Warming the battery with your hand is sufficient to detect a small change in resistor value when looking for the correct terminal on the battery. After repair, the fuel gauge might not work, is inaccurate or provides wrong information. The battery may need some sort of an initialization/calibration process by fully charging and discharging the pack to reset the flags. A “flag” is a measuring point to mark and record an event.

The circuits of some smart batteries must be kept “alive” during the replacement of the cells. Disconnecting the voltage for only a fraction of a second can erase vital data in the memory. An analogy is open-heart surgery where doctors must keep all organs of the patient alive. The lost data could contain the resistor value of the digitized shunt that is responsible for the coulomb counter and other data. To assure continued operation when changing the cells, supply a secondary voltage of same voltage level through a 100-Ohm resistor to the circuit before disconnection. Remove the outside supply only after the circuit receives voltage again from the new cells. Furthermore, some fuel gauge chips run wires to each cell.

These must be reassembled in the correct sequence beginning with cell one, then two, three and so forth. You will also need to be aware of compliance issues. Unlike other regulated standards, the SMBus allows variations and this can cause problems. The repaired SMBus battery should be checked for compatibility with the charger. Batteries for critical uses, such as heathcare, are typically replaced and not repaired.

See also and. Simple Guidelines when Repairing Battery Packs. Only connect cells that are matched in capacity. Do not mix cells of different chemistries.

Never charge or discharge Li-ion batteries unattended without a working protection circuit. Each cell must be monitored individually with a protection circuit. Include a temperature sensor that disrupts the charge current on high heat. Apply a slow charge to a repaired pack to bring all cells to parity. Pay attention when using an unknown brand. Elevated temperature hints to an anomaly. Li-ion is sensitive to reverse polarization.

Observe correct polarity. Do not charge a Li-ion battery that has physical damage, has bulged or has dwelled at a voltage of less than 1.5V/cell for some time. Check a repaired pack for self-discharge. Intrinsic defects often have high self-discharge. Last updated 2016-01-29. Please Read Regarding Comments.

Ramya, answers: 1 -Can the laptop be used without battery but being plugged in? Of course in the event of power failure it will go off on the moment. 2.If battery is charged fully but stilled being plugged in, what is the risk? Li-ion batteries permanently lose capacity.

The rate of losing capacity is proporcional to temperature. IF they are exposed to hot temperatures they will have shorter lifes. So, best way to prolong battery life is to charge it to full capacity and store it in the fridge when not needed. Its not very practical dough. 3.In certain circumstances of updating, Windows needs th laptop to be plugged in,why is it necessary/ This happens whenever the time expected to complete the operation is very long.

So, if the computer was being run on battery it would be probable it will discharge before the task was done. Dear Purchasing Manager This is Leo from Better Power Electronic Co.,Ltd. Factory directly with best price and qualtiy laptop battery. CE+RoHS certification.

Hello, I was inquiring about the C7000 series in order to wake up a couple Dell laptop batteries that have resisted taking any charge after being away from the laptop for an extended period of time. I was given the following as part of the response: “Testing Dell Laptop batteries, can however, be a challenge as in many cases they have a protection circuit in the batteries which doesn’t allow it to “handshake” or communicate with the analyzer to get the charge going.” 1. Is there any reliable way to get around the handshake issue? How do I know which Dell laptop batteries have that problem?

I understand it was only the older laptop batteries and not the newer ones that are affected. Is that correct?

Thanks, Steve. Hello i have a Toshiba laptop with a camera and mic -dont know what else- My battery has said that it needs replacing, But it charges up fully it has said this before and then a few days later the battery was fine, and the battery was fine just a few hours ago but i cut off the laptop while i went to the movie cut it back on and the battery needed replacing, Does this mean the battery really means replacing or that the computer is messed up or something like that? Please Please Please Answer Me! Hello, I need some help.

My laptop (Acer Aspire 5742G) only works on battery power, and not through the A/C connector, even when the battery is disconnected. I have done multiple checks to confirm this. Would it be possible to connect the A/C power to the battery port directly, since this is the only way to feed power into the Motherboard, and if so, how. I shall give a few ideas I have come up with, any thoughts are welcome: 1. Removing the cells in the battery and connecting the A/C terminals directly to the battery terminals, hence feeding A/C through there. Leaving the battery intact, but insulating off the negative and positive terminals of the battery, then feeding A/C through these terminals onto the motherboard, to “trick” it into thinking a working battery is connected.

Thanks in advance for the help. Why, oh, WHY do 85 percent of the people who post comments seem COMPLETELY incapable of reading and / or thinking??!?!??!!!?? This ENTIRE SITE is dedicated to battery technology people! Damn-near any question you could think of is answered SOMEWHERE here. You see those headings and sub-headings to the left of the page? They take you to other parts of the site dealing with the information suggested in each heading. Put in just enough effort to open up a couple other pages on THIS SAME SITE and you’ll have your answers!

Don’t be so damn lazy you can’t even do that! Of course, daft questions like “where” to get specific parts, replacements, etc. Are NOT going to be found. You realise this is the Internet, no? And that the author(s) of the site probably DON’T live anywhere near wherever you are. So explain to me how you expect him (them) to be able to provide answers like that?

Apologies, but I’ve been going through a number of different pages on this site, and I see the same idiocy repeated painfully on near every one of them. Good luck guys, I don’t mean any harm, I just want you to think - just a little -for yourself, and exercise your clicking finger a little THANKS FOR AN INCREDIBLY COMPREHENSIVE AND INFORMATIVE SITE BTW!!! Hi, is it possible to simply bypass a solid state switch that requires an activation code? What if one solders the positive terminal of the battery pack directly to the positive pin of the connector? In my case I have a 3 cell battery pack from a lenovo netbook, ideapad s10e.

It has a 7pin connector. The first pin is the positive and the last (the 7th) is the negative (ground). The individual cells are all new and fully charged (4,2v each). Being connected in series the voltage of the pack is 12.6v. However, the solid state switch cuts off current to the positive pin. What if I connect it directly to the red wire from the battery?

Thank you for your time! My HP laptop G series battery has hardly ever been used.

My sister has the same laptop and she uses hers all the time, has even had it longer than mine. She keeps her battery charging all the time. She has no issues. Just out of the blue, my battery won’t hold a charge for very long. I read online that you can “jump start” a battery with a USB cable with the positive and negative wires stripped. Basically, you zap the battery.

The online description talks about locating the positive and negative connectors but doesn’t make mention of these laptop batteries like in the pic above. Is there a way to jump start the battery or to do a reconditioning procedure (whatever that may be) to get the battery to hold it’s charge? Right now, it only lasts for about 30 minutes when in the past it lasted for several hours or more. I have fujitsu ah530 laptop i tried to replace the battery cell of my old battery with the same voltage and amphere cells but I failed the battery’s Positive terminal does not have any charge. I arranged another old dead battery from my friend but same results. In both senario the +ve terminal is not having any charge, when placed to laptop it does not start on battery showing error “0% charge plugged in charging consider replacing your battery”. How to on solid state switch so that their would be a charge on +ve terminal and how can I resolve the issue please help me.

I hv a compaq 6710b as with many laptops you can buy them with 6 cell battery of if you add more money, you get 9 cells i was wondering if i could replace the batteries and make it a 9 cell battery my question is wouldn’t it add more volts to the battery if you add 3 more cells to an ordinary 6 cell battery? Anyone any idea about difference in 6 cell and 9 cell, how it is made to work with same laptop? Would i be able to use the same chip board as 6 cell one with 9 cells? My battery v10.8 55wh 6 cell. Can some one give me pinout for HP zt3200 battery model no cs-cnx7000 or equivalent?

The problem currently I have is the following. When the laptop is powered on through mains adapter, charging indicator red light of the laptop comes up for few seconds and the light goes off.

How To Open A Battery

Laptop boots normally. On checking the battery status it shows 0% charge.

I had taken out and opened the battery. One pair of cells were dead and I replaced those cells. Discharged all ceels manually.

Then charged the cells manually upto 3.7 volts. Individual Cell voltages were from 3.69 to 3.71 volts. Put the battery again into laptop but the problem remains. Battery showing 0% charge but it didn’t charge. I have checked the voltages at pins. Several pins show voltages ranging from 2.5 to 14 volts.

However, non of the pin takes any load indicating that the battery is not allowing power to flow out i.e. The output current seems to be limited by the electronic circuit attached to the battery.

Any help would be appreciated. Notebook: Dell Isnpirion mini 12 I bought a replacement battery for this notebook because the original Dell (design capacity 48 Wh) has lost its capacity in the years. New battery: Typ: NDE076 Capacity: 58 Wh or similar (not 48 Wh!!! - this was the original Dell) This replacement battery has been replaced in warranty 3 times in 1,5 years!!! Because somehow after time its controller circuit gave up. That means no charging, no energy, no charge report anymore. After the 3rd replacement i deciced to open it and saw the controller (Atmel mega406).

The cells were charged, somehow the controller went in a state (probably blocked) that i had to reset it. It has a RESET pin That helped and i had to full charge and full discharge to teach the controller again. I think i will have to repeat it if the problem occurs again!

One must know there is a firmware in this controller and this “blocked state” issue can occur due to a firmware/hardware bug. If you have a warranty don’t try this, just claim for a replacement. Hi I have Samsung Series 9 ultrabook NP900 X3B A01UK.

This ran out of charge and the light on the charger was not on. I replaced the charger with an originL Samsung unit the laptop powered up however the charger appeared to fail immediately and the laptop shut down. On unplugging the charger it was quite warm and again the power light is not on even though the fuse has not blown. It appears something in the laptop is causing the charger to fail. Do you have any advice, could this simply be caused by a failed battery or something more seriously wrong with the laptop? Kind Regards Len.

I use an ASUS F200 LA computer. The battery was not charging.

When plugged in, it will display charging, but it won’t leave 0%, and it switches off immediately when it is not on an external source of power, so an engineer helped me in boosting it by charging it through its positive and negative terminals after loosing the battery, then it charged to 58%, but it will still not increase when charged with the laptops charger, and when the power adapter is unplugged, it switches off immediately. Please what can u do. My ASUS F200 LA battery won’t charge, and it won’t power on my system. I had to dissipate the battery of my system sometimes ago. Since then, it has not been charging. When plugged in power, it will say charging, but it won’t increase, and whenever I remove the power cable, it will power off immediately.

Today, a friend assisted me in boosting the battery, by removing the inbuilt battery, and charging it through its positive and negative wires. When we inserted it into the computer, and attempted to power it on without the adapter, it did not power on.

When we inserted the power cable, the system came on as usual, but now it had charged to 58%. Yet it won’t power on without the power plugged into electricity, and it will power off immediately the electricity is disconnected.

What I know is that; The battery cell can be charged directly, but not with the adapter. The system is only working on external power not on battery. Please what can I do to rectify this problem? If battery doesn’t hold the charge then it is considered dead. Dead batteries seem to be charging to even 100% but they don’t have power to keep laptop powered on.

Now when I connect the battery to laptop it says fully charged but when I unplug the AC adaptor the laptop shuts down imidiately like I have no battery on it. I checked all connections and all it’s fine. The plus and minus terminals of the battery have zero volts but the cells have 11.5 volts. I use the resistor to activate the solid-state switch but with no luck. I have to mention that I replaced the cells without keeping “alive” the circuit board. Why is this happening? Is there any way to bypass the board?

Hi, my P755-S5285 Toshiba Satellite Li-Ion laptop battery pack PA3817U-1BRS seems to have died.10.8V 4200mAh. Inside it has 6 x SANYO K UR18650A R2112 cells 1. Can these be safely replaced? What are the best replacement Li-Ion batteries to use to replace the SANYOs?

Is it 3.6V or 3.7V? What mAh capacity would be best to use?

Can I increase the 4200mAh to what amount and how? What do the ‘‘K’’ and ‘‘R2112”’ and ‘P23B’’ etched on the cells’ plastic covers mean? How can one identify and differentiate clearly between the various types of these Li-Ion batteries? Thanks to all your comments and advice. Hi, I mistakenly, connected a reversed polarity charger(19 V) to my ASUS notebook, it shut down instantly.

I removed the wrong charger and connected the correct one and started the notebook, it started normal and run for 1 hour, showing 0% charge,with charging message. After 1 hour it shut-off. I started again, it started for 5 minutes then shuts off. I removed the battery, plugged the charger, it does not run at all. But with battery installed it runs for few minutes then off again.

I tried many times, same thing. I think the notebook only runs on battery now as the 1 hour work was due to a remaining charge in the battery.

I plugged the charger for hours, orange LED indicator is on, but when starts for few minutes it shows 0% charge-charging Wondering what is the expected damage and how can I charge the battery without installing to the notebook? To Nadahm How to recharge the battery?

The answer depends on many factors. Mostly on the tools (hardware = material that you have) and intellectual tools, knowledge) note that my method is not necessarily economical!

How I do, I have a milling machine; I bore a hole at each end of the battery at the center of the cells location By doing this, it enables me to have access to the cells within the battery and measure the voltage Usually it is not sufficient; I bore some holes on the top of the casing (opposite side that is externally exposed on the laptop) That gives me access to each cell. From there I poke wires and recharge each cell individually I charge at 4.0V and 0.5A max rating for each cell. The reason is the cells are not dead equally, and because they are connected in series, the weak ones would receive too high of a charge rate This could result in fire or explosion Google, e cigarette on fire if you want to see what is involved After the charge and equalize operation, the battery assembly is placed in the computer The next step is, does-it communicate? I use a software batterycare to find out If the battery does not communicate, its useless to peruse = scrap If it communicates, one would see the state of chargeand so on However, sometimes (often) there are damaged components on the battery management board Again I cut the casing, without destroying-it!

Very often it is the protection device (a fuse system) that is blown, I repair-it as oppose to replacing the part As you can see this is not economical!
