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!

I have a laptop asus k53sm. Which cells shall i use to repair its battery and how can i open it. I do not see any clue to open it ? Thank you
After a visual inspection to make sure there are no burns anywhere, check to make sure the voltage of the battery is within spec. Also, check to make sure it's holding a charge by checking its voltage with a multimeter right after you charge it. Another thing you can do is feel the battery to see if any particular spot is producing more heat than other areas of the battery pack. If after doing those things you feel like your battery might be bad, then you will have to tear it down enough to be able to measure the voltage of each cell group. Find the group or groups that have a lower voltage than the rest of the cells and remove it from the pack. After that, those cells just need to be replaced.

When building a battery pack you have two main options for a BMS either a common port or separate port BMS. In this article, we discuss the main differences between the two types and offer our opinion on which is best for certain applications.
Every time your battery falls below the voltage range that it was designed to work at, there is permanent damage done to the battery cells. This, itself, is not dangerous but it is very bad for the battery.
I have a PowerBook g4. The power port on My dc in power board where my power cord plugs in has gone bad. Apple doesn't make the part anymore so now I'm stuck with a computer that can't power up. I saw that they sell an external battery charger for all laptops. Is it possible to use my existing power cord and hook it up to my battery to charge it? If yes can you describe in detail how to do so?
However, if you have refill caps on the top of your battery and if you are sure that you do not have an AGM or GEL battery, you can follow these steps to recondition your car battery:
Make sure that you use NiCd batteries with a typical capacity between 450mAh and 800mAh.
I've seen an atrouceous comment here advising to discharge the battery completely
You can begin by going to Apple Support and finding a local Apple service provider near you. Once scheduled, you can drop by the service provider. Depending on the case, they might suggest sending it to Apple Repair Center—the downside is that it may take some time before your device gets returned to you.

Tip the battery on its edge and allow approximately half the battery acid to run out of each cell and into a plastic container. Clean the battery with your paintbrush dipped in a baking soda solution as described in Step 2. Rinse your battery with plain water, making certain none of the water gets into any of the cells.
My laptop battery has it terminals shaking. Wanted to ask if the battery is damaged or not.
