Hello,
Alot of what I know may be an Old Ives Tale. I do not think it really
makes a difference as to the temperature (other than items should not be
about to burst into flames). I heard it is best to fully charge a battery
before using it again. It is not the best but somewhat okay if you have to
stop charging that you continue charging again later on without discharging
the battery inbetween. I also try to let the battery go down to 5 to 10
percent then I recharge it.
Having the machine on usually slows down charging. I think it is due to
part
of the current from the power supply being used to power the computer
instead
of charging the battery.
Talk to five laptop users about batteries and you will get seven different
opinions!

Subject: "Optimal" Battery Charging Technique?
All~
Does it matter, when you're charging the battery, whether or not:
1) the battery pack is hot/warm/cool/cold?
2) the AC adapter is hot/warm/cool/cold?
3) the battery is charged with the machine turned on, or off?
I always charge cold batteries using cold AC adapters with the system off,
usually overnight. And I never use the battery before it's done fully
charging.
Just wondering if this is a waste of time & effort.
Thanks, kj
