[Giz] How To Take Care Of Your Li-ion Battery

post #1 of 36
Thread Starter 
Quote:
Lithium-ion batteries! They’re in your phone, your laptop and pretty much every consumer electronic device that uses rechargeable batteries these days. How should you take care of them? Old wives tales of charging batteries don’t apply here, so forget everything you thought you knew. According to Ars Technica, this is how you should use your Li-ion battery:

• Do not let it run out completely all the time. Full discharge puts a lot of strain on the battery
• Do not keep a Li-ion battery fully charged all the time, either. If you don’t use your battery it might suffer from capacity loss
• Keep your battery in cooler temperatures. Hot hot heat is not good for it
• If you’re gonna store your battery, leave 40%-50% charge in and store it in a cool place (i.e. fridge).

Figured I'd post this since this was the topic of much debate here not long ago.

+1 to what they are suggesting. Also, NEVER put Ii-ion batteries in the freezer. that will completely kill them.

People never believe me when I tell them they shouldn't empty/fill their handphone/laptop batteries.

Interesting.
I usually leave my Li-Ion crap plugged in whenever possible, haven't noticed a huge degradation in life from keeping it 100% charged.. My laptop from 2006 still gets around ~70% of the battery life on the original and it's been plugged in sometimes for months at a time.

Usually its also a bad idea to charge a battery to full, the battery monitoring circuit is not perfect and may over charge. Most battery chargers will slightly under charge anyways.

Ive read for the longest time that never should you completely let your battery drain BUT at the same time never leave your device fully charged either. T

he electrons and what not die out fast either way over time, and it all dries up. You should, once a month, let the battery die out to about 10-20% and then let it charge to 100% + an additional 30 minutes or so. Then continue with use and never let it drop below 50% or so until the next month. I've been following that rule like a freakin life commandment.

Running @ 333mhz and watching youtube videos on my psp killed my battery. Ran completely down and wouldn't recharge. So i made a bomb.
