How to Prolong Laptop Battery Life September 2, 2008
Posted by Da in Misc.trackback
I recently observed the death of a DELL laptop’s battery. Fearing the same may happen to my laptop, I did a little bit research and record them here. (Most of the content below are adapted from wikipedia)
Basically, nowadays most (if not all) laptops use Li-ion batteries, which does NOT have the memory effect, but discharges itself at a rate of 5% per month, and it seems that this would result a permanent loss of capacity. So to slow down (and not to speed up) this self-discharging effect, we need to:
1. recharge the battery early, unless it won’t be used for a long time. (avoid frequent full recharges)
2. keep the battery cool. The higher the temperature, the faster they self-discharges
3. do not store batteries for long periods plugged into or attached to any power source. This includes AC adapters and laptop docking stations that are plugged in.
For more information, please see the article about Li-ion Battery at Wikipedia and its references. DELL provides an FAQ here too.
Useful. Thank you!
the death of a DELL laptop battery? that’s not very accurate.. it’s still alive.. and running.. just “reaching the end of its usable life”.. =)
