Tangential but as an effort to go green- I'm considering not buying new Led acid batteries for my UPS and reusing the old ones from my old laptop. Does anybody know if this can be done?
- TheSpiceIsLife 7y agoFair chance old laptop batteries are going to be well and truely past their serviceable life. Lead acid batteries are highly recyclable, and more easily recycled than lithium ion cells anyway.
- 22dingdongdung 7y agoBy old I mean used not old-by-age. I usually buy a new laptop every 3 years
- TheSpiceIsLife 7y agoHave you looked in to what’s required to balance-charge the cells? I’ve seen some blog and YouTube videos where people have repurposed 18650 lithium ion cells. There’s a bit to it, but it’s doable.
- pmorici 7y agoNot going to work and probably not safe. The nominal voltages of different battery chemistries are often different and you can’t use lithium ion chargers interchangeably with lead acid chargers. They make LFP batteries that are backwards compatible but those aren’t used in laptops.
