"Fully empty your battery before charging it up again, it increases the lifespan of the battery."

This was true before lithium-ion batteries became the norm. But for lithium-ion batteries, the opposite holds.

Remembering which of my devices are old method charging and which are new method is a pain.

I have several camping lamps from like 20 years ago that I almost threw out because they weren't holding charge anymore, before I remembered to be fully draining the batteries and recharging them once a month. They work like new now practically.

What's the opposite of "full empty your battery before charging it again?"

[-] Atemu@lemmy.ml 22 points 3 days ago

Don't let it uncharge fully. You ideally want to stay in the 30-70% range as much as possible.

[-] SkaveRat@discuss.tchncs.de 5 points 2 days ago

From time to time you want to let the battery go from 100% to shutting off, so the charging circuit can calibrate the reported capacity

Also, charging it to full is much better than letting it die until it’s empty.

I’ve also heard 40-80%

Thanks Jaime!

Well that one is still true if somehow you still have Ni-Cd batteries in your life.
