Packages come in many different and sometimes bizarre-looking arrangements but if in doubt, check the spec sheet and MSDS (Material Safety and Data Sheet) of any chemical or device you intend to work with. Inset the knife along the edge. It will take a while, but be patient. However, this could reduce battery life on newer lithium ion batteries, so for those batteries it’s suggested you only let the battery level drop to 35% to 45% and then charge it back up to 75% to 85%. : There are many ways to construct a battery system for a portabel device or vehicle. You need some basic tools, so here are the essential ones: Flat blade screwdrivers. Multiple cells are either in series or parallel, or a mix of both. That said, you must use an appropriate charger, either for single cells or one that supports multiple cells in a pack such as a balance charger. I am taking apart two battery packs in this tutorial. Taking a look at the arrangement of the batteries, the laptop battery has 6 cells in a series/parallel arrangement, so 3 cells in series to generate the 11.1 volts, and 2 cells in parallel to double the capacity to 4800 mAh. Series connections increase the voltage, and parallel connections increase the capacity of the pack. A sturdy metal one, or strong plastic one for separating cases. I tried many other Google related tips but once again, Instructables came up trumps. Restoring/Recharging Over-discharged LiPo (Lithium Polymer) Batteries! Use the side cutters or the flush cutters to carefully cut the tabs between the cells and avoid shorting across the terminals. All is not lost because you can revive them. Find the seam between the two case halves. Plus, they don't develop a 'memory' or have high self-discharge so you can store them a long time. Thanks for sharing the tip and glad you liked the tutorial. Lithium-ion batteries operate best when they are charged off and on throughout the day. Why? I had planned on it, but never got around to it until today so thanks for reminding me! Plug the battery into your Lithium Ion charger and give it a full charge. You can salvage the very low voltage cells, but you need a special charger that can 'revive' dead batteries, or use some techniques that can bring them back to life. *two bandaged thumbs up*. For cutting tabs or wires, or cutting the battery case open. Lithium-ion cells don't like to be discharged below their over discharge voltage, usually between 2.5 and 2.75 volts at the most. You can run some test cycles on them to see how much life they've lost as well by doing a charge-discharge cycle or two and check the capacity. But a few questions are needed. For example if your battery is rated at 3.7 volts and the voltmeter only shows 1.5 V, it may be in sleep mode. Lithium-ion batteries are sensitive to over and under-discharging. Can’t remember if I used it successfully on batteries on their own. If one cell gets more charge than another one, it can wear out faster or get damaged. I think they are 18500-size lithium-ion cells. Find out how to prolong battery life by using correct charge methods. I learned this the hard way! More on that later! Set the charger to the LiPo/Li-on mode and charge at a low current, like 200 to 300 mA. It's because the chemistry of the lithium cell makes it sensitive to over charging, over- discharging (draining until the voltage gets too low), short circuit, and even over temperature. My Nikon camera stopped charging and wouldn't turn on! The Zanflare has the ability to revive dead batteries and has an analyzer function, but the iMax doesn't. It will give up before you! Multimeter. Works better than a spudger, but more dangerous! Plus, they are less stable (read: dangerous) than the other types and need to have some kind of protection circuitry. After some finaggling you should have the case fully or mostly separated and can behold the goodies inside! Charging and discharging batteries is a chemical reaction, but Li-ion is claimed to be the exception. Windows showed 0-volts on the battery icon (notification area). If you're stuck, resist the urge to use a hammer or break out your Dremel tool with a cutoff wheel. You can check the age of the battery pack, and measure the voltage (if able), or check for date codes on the circuit board inside. A number closer to the original capacity is good, but if your cell discharges rapidly, gets warm or hot, and has low capacity, then it's time to recycle it. Thanks again! One is a generic 6-cell pack for an HP Pavilion Dv 5 to Dv 6-series laptop and a pack from an ancient (2004 vintage) digital camera rated at 7.4 volts and 1500 mAh. I like to start at the corners of the case with the utility knife first. If you still only get a red flashing light and the battery won’t charge, boost the battery some more. 2 years ago. For the record, I've never had to use mine. But maybe that was devices and the thermistor / thermocouple in the tablet etc. "In case you've ever wondered, the name of the battery contains its dimensions. The capacity of the pack is also reduced. The way to avoid this is to handle and charge them correctly. Set the current to something like 200 mA and start charging. If they have significantly self-discharged, then toss 'em, but if they're still holding the charge then chances are you've revived them, but time will tell as you use them whether you are successful. Lithium cells in battery packs are always connected by spot welded tabs that connect the positive and negative terminals and you need to be careful when cutting them. The laptop pack has some pretty decent Moli Energy (now called E-One) brand ICR-18650J cells. The cut edges of the tabs are razor sharp! The internal chemistry is similar to lithium-ion cells. Share it with us! Ask my fingers and hands how I know this 8). Is this what RYOBI recommends? Practice shallow discharges with your device. Multi-cell packs have an added feature called a battery management system with a balance function that monitors and distributes charge current and voltage across each cell, making sure each gets charged with the same amount of current and voltage. Thanks for the information. It's good to have various sizes, but generally 3 mm (1/8") up to 5 mm (or 1/4") are all you need. This is due to the fact that some devices have increased voltage needs more than a single cell can provide, or to add capacity. The "0" is just hanging out. Monitor the voltage until it gets above 2.8 and stop the charging process. ), check, and revive salvaged lithium-ion cells. Unlike NiCad batteries, lithium-ion batteries do not have a charge memory. If the voltage is below 2V, the internal structure of lithium battery will be damaged, and the battery life will be affected. I have an affinity for lithium-ion batteries. It makes sense though since this is the original battery from 14 yeas ago! I think everyone should take something apart with no idea on how or intention to put it back together! This doesn't mean the battery is as good as new. How to Fix Dead Lithium-Ion Batteries That Won’t Hold a Charge Anymore. You can use a sturdy spudger here as a wedge to keep the halves spread open while you work the screwdriver. I'm going to explain how I have constructed one for an Electric Longboard and one for a portable Loadspeaker (aka Boombox). Lithium batteries used to die after a few years (I think oxygenation) even if never used. I had forgotten that you can short out on the metal can of the battery if touching the positive or negative terminals. I measured it after I dissected it and it was a pretty-much-dead 5.6 volts with each cell reading around 1.8 volts. Connect the corresponding terminals on each battery to each other with 14-gauge copper wire. If you're like me, then you're always looking for an excuse to save money, tinker, or deconstruct something that seems interesting. 1 of the 18650's is now back to its full capacity. I have an affinity for lithium-ion batteries. Extracting cells is pretty straightforward. The batteries I have are 4 cell 18650 with built in bmd boards. It will take three or four times longer than previously as the reconditioned drill battery can hold more energy. You should start getting large creases in the case. OEM batteries are usually glued/welded and cheaper ones are glued or clipped in. Take a voltage reading with your voltmeter. I’ve put lithium batteries in the freezer to get them to charge again. The safety consideration comes if they are short-circuited, over charged, or under charged, or over discharged, the most common type of lithium battery heats up, swells, and can explode, or cause a fire from getting so hot, which we don't want.

Use the glue gun to fill in the space and to attach the other two legs to the battery holder so it will stand firm. Now what? While it's okay to keep the cells connected, you will want to separate them for charging and analyzing. Knowing these simple tips for properly charging your lithium-ion batteries will take a long way. If you aren't getting anywhere, go back to the knife and repeat the first step. Turn on the charger and allow it to charge. Avoid thicker blades as they are too big to fit into small spaces. Strap 6 or more together, and you have a lot of stored energy. In most cases I rarely if ever use the corded tools they replaced, despite this there does seem to be a major week point, the batteries. So please read on to learn how to recondition NiCad Batteries. 3 months ago, Wow, I like what you've doneI think I'll start something like this as well, Reply Ni-cad batteries lose charging ability due to memory loss- if you charge a Ni-cad with 20% left, you lose the 20% over time and can only ever recharge to 80% capacity. I'm in the process of rejuvenating a couple of 18650 Samsung Vape batteries. If they read 0 volts, then they have entered a sort of hibernation state and are probably not worth keeping as even if you revive them, they will have been damaged. How do you fix a lithium ion battery that won’t charge? I cut the battery open and it had 9 cells (18650 Li-Ion). Below that and the cell goes to "sleep" or is so dead it won't take a charge anymore, and if you do manage to get charge in it, the capacity will be so low that it's unusable. I never even gave my iMax Pro Balance Charger a thought until i read this page. The problem with salvaging batteries is you don't know how well they were cared for or how old they are. I checked the data sheet and they are 2400 mAh capacity and rated at 4000 mA discharge current maximum, 4.2 volts full charge and 3.75 volts nominal charge, and 3 volts discharged. Great suggestion. You’ll need to completely drain the battery for this to work, so once it reaches zero percent, keep turning it back on until it doesn’t even have enough power to boot. Did you make this project? 2. Lithium-ion batteries may go into sleep mode if you drain the battery too much.
