View Full Version : [all variants] feeding the lions: laptop batteries

January 21st, 2009, 11:29 AM
According to Wikipedia (article Lithium-ion battery, sec 7) these Li-ions degrade much more slowly if only charged to 40%. Therefore it seems desirable if one could switch the charger between 2 states:

1: when at home, with ready access to power: charger to switch off when it reaches 40%.

2: but when you are going to travel: charge battery full.

Please has anybody done this? is the charger controlled by hardware or software? Thank you.
