I have a Dell Inspiron noticed my battery life was really bad, but I keep it plugged in most of the time. It got to the point that it went from 100% to 0% in 10-15 minutes. Well it was out of warranty so I bought an OEM one from eBay.

Well now it doing the same thing (<6 months later). What is it about my laptop that kills batteries? Is it the batteries, will a more expensive one work better?

My wife's laptop is a year older than mine and the battery last ~2 hrs easy.

Any advice?
 
Leaving it plugged in most of the time while running on A/C can shorten the life of the battery because it is constantly recharging in dribs and drabs. If you use your laptop a lot under such conditions, it is sometimes better to completely remove the battery. BTW - is it a li-ION or NiMH battery?
 
he is right my laptop battery is now weak they say it is normal but recommanded me to get new one I leave my laptop plugged in 24 hours and 7 days after unplugged for 4 months while i was gone exile. oh by the way my laptop is only a year old now
 
I was thinking this in the car before checking back here, it makes sense. NiMH only have so many charges in them, so if the constant charging/discharging while plugged in couts towards it's life then I was killing it. I typically leave my wife's unplugged hence her is battery last longer. So I assume this is not reversible, I need a new battery (again) and need to be careful on how I treat it? Thanks.
 
Just leave your battery out if you are using your lappy plugged in on your desk most of the time.

I stick my battery back in every fortnight or so, and run it till the power meter says its critical, then put it back on mains to recharge.
My Dell lasted a little over three years doing that, and still had the legs to run a full length DVD plus change before it went flat. Guy I sold it to is still on the same battery after 2 years. It's getting tired now, but doesn't owe either of use anything.
 
NiMH is an older battery technology. When you get a new battery that is NiMH, the best practice is to completely charge it, then completely drain it, called "Cycling" the battery, you should do this a couple times or even a few times right when you get the battery, that will ensure no bubbles form in the cells and cause a lesser battery life. As maintenance, you should also be sure to cycle the battery one or two times a month thereafter. The best way to do this is to just unplug it and walk away while its still on, then when you come back a couple hours later and its off, you know the battery is dead and you can plug it back in to start the second half of the cycle. When cycling, just make sure to set your power options so that the computer will not stand by or hibernate at any particular battery life percentage, you want it to stay on until the battery literally cannot supply any more power to the machine.
