And this video I'm going to show you how to safely open laptop's battery pack without damage in the case and internal cells, and some ideas for a parent and old cells use this 70-year-old HP battery was used only a few times, but the battery controller decided that it's time to buy a new one and disabled the battery. This may happen, even though the cells are still in good condition, or at least some of them. Alright. For this project you need a cutter or a knife with thin blade and a flat screwdriver. The first thing you need to do is careful with Pierce. They seem to don't go too deep, just about two millimeters and then turn the blade down and slowly pry around.
This may take a bit of force, especially at the corners original GP. Batteries are very well gluten. You have to be patient and careful anyway, it's not easy to damage 18 650 cells compared to pouch type cells, HP and Dell battery cases are made of very flexible plastic and, as a result, accent breaks crack resistance, as you can see at this batch arcades in absolutely great condition, and you can do these parts back together with regular superglue. Okay inside we have six standard, 1816, lithium-ion cells and smart battery controller, which has not only safety or communication with your laptop functions, but it also counts charge/discharge cycles and at some pre-programmed point simply blocks your battery pack. If you simply replace these cells, your battery pack is not going to work.
Moreover, you must disconnect- and this controller, in a very specific order, usually starting from positive terminal, otherwise controller will block itself and send signal to burn they self protector fuse. And, finally, you have to buy some specific equipment for reprogramming the chip that stores all the history of your battery use and unfortunately, it's the only way to reset its memory back to new condition. I'd recommend you buy not original battery for 15 bucks from AliExpress, which is very easy to open, and their controllers never block itself, so you can easily upgrade it with high quality cells or, if you pay more, you get the same quality battery as the original one or even better. It lasts longer and even feels heavier okay in case, if you just want to get to these cells, the best thing you can do with them is to make a power. Bank I have already reviewed some power band cases for one two and six cells.
The link will be at the end of this video and in description below this three sell. Carbon case costs only two dollars with free shipping and there's also a model with four cells. The link in description below both are made of aluminum and can deliver up to one amp of current, very simple schematics, with charge controller and DC converter based, and a single chip, on/off button and a faulty battery status indicator using pliers or tweezers. Remove the ribbon cable. If you don't have a multimeter, you can test every single cell simply by charging and using them one by one and then select three cells that last longer make sure to insert cells correctly.
Here's positive terminal and the negative one I now put all the parts back together. This power band can charge my phone up to 80%, which is not bad for a seven-year-old cells and, as you can see, claimed one amp output is real.
