Dell battery question

Dell battery question
My battery wear level is now 2% after about 2 months and I've only recharge n discharge it about 7 or 8 times , is that normal?
I've always charge my battery after it falls to 1% ,is that the correct way to do it?
cause I've heard that rechargable battery must be emptied before recharge if not it'll ruin the battery life :confused:

Re: Dell battery question
do you put the battery in hot temperature?
Answer:
Re: Dell battery question
no ,not really ;about 35-40 C
Answer:
Re: Dell battery question
if you charge it 100 percent and at that temperature in a year it loses about 35 percent charge. If you do charge it a hundred percent use it to get it around 40% and in about a year you will only lose 15% because at the temp you are at it loses more charge.

Re: Dell battery question
the temperature i mentioned is when I use it to play games , I always charge my laptop while it is OFF so technically there's no heat at all

Re: Dell battery question
This is interesting, I just asked this in another post earlier last week: What's the best way to charge the battery? when the computer is off?
Also: I'm getting mixed results on new batteries: I have a d620 arriving tomorrow, should I charge the battery once for 7 hours (on or off?) or start using the PC right away?

Re: Dell battery question
When I first receive my E1505 I use my battery until 1% then I recharge but now I'm confused by this issues and if I don't figure out the right way to solve it my battery is going to be useless in 2 years (wear level 50%=minus 1.5 hours of battery life)

Re: Dell battery question
what i find to work is charge my battery and blow a fan at it because when you charge the battery the battery gets hot. When the battery is not being used get the percent down to 40 and put it by a van or a cooling vent so that its temp is low

Here's a good read on lithium batteries: http://www.batteryuniversity.com/parttwo-34.htm
Don't deliberately do deep discharges other than to recalibrate the fuel gauge. 2% after two months is very normal if you leave the battery in your notebook. Lithium-ion batteries have shelf lives, even if you don't used the battery it'll deteriorate.
