I just got a pretty good deal on an old ThinkPad (think 10 years old now) to use as a beater for screwing with ArchLinux and hopefully to find a real use for. It’s in great shape like it was never really used, but big shock, the battery is at 50% effective capacity and what’s there disappears in less than an hour.
Would you bother buying a battery replacement for it? On one hand I want it to actually be usable on the go because that was sort of the point. On the other, while replacement batteries exist, I’m worried that they’re already very old themselves and already “expired”. Would you take the chance? I don’t want to let this thing go to waste when it’s still perfectly usable, in fact it’s pretty fast.
What kind of terrible advice is this?
Absolutely do not start ripping apart your old laptop battery to replace cells if you don’t know what you’re doing. Depending on the battery size and type, you might also not have many cells at all to replace.
You would be better off buying a cheap replacement battery, especially if it’s already 10 years old. Any cells that aren’t bad today will likely be very soon.
Telling people to pop open a Li-Ion battery is asking for a fire. This is why I wish Beehaw supported down votes. Dangerous advice like this is exactly what down voting should be for.
