If you want a cheaper battery wouldn't it be simpler and safer to replace the cells in an old Lenovo battery than to buy one of these dubious copies? That way the charge electronics are all correct and you can also control that the cells are good quality. There are even places that will do that for you if you're worried about poor soldering or other issues with doing this kind of swap.
- xnzakg 11y agoHe did mention that possibility in part 1. The reason he didn't do it is because it's hard to open the original battery without damaging the case.
- userbinator 11y agoThe monitoring circuits in some batteries will permanently disable them if the cells are disconnected, and need a special programmer to reset them the way they came from the factory.
- tim333 11y ago>wouldn't it be simpler and safer to replace the cells Dunno about safe but I've bought maybe 5 unofficial replacement li ion batteries for thinkpads, 2 for the iphone and will probably get one for my macbook. It takes about 1 min - go on ebay click buy, arrives in the post. It's hard to get much simpler than that until this recent lock down stuff. I've had no problems except the cheap knock offs don't generally last quite as long as the originals did when new.
