I finally came into the posession of a battery that will fit my old laptop From what I gather, it has never been charged before.
But it has been in storage for about 4 years.

Are there any tricks or care tips that i should follow in order to best bring it to full charge so that i can squeeze as much life out of it as i can?

translation - i want to jew out my laptop battery

honestly i would think just letting it charge up for a while before turning on the laptop would be good, and everytime you have your computer plugged for long periods of time in take out the battery. I told a friend about my shitty battery and she said after she got a new one the guy told her to take out the battery when its plugged in...she said it had definitely helped her battery life of the newer one

IF it's a nickel cadmium or nickel metal hydride pack, then your chances of good, full battery life are pretty damn good. I'd just do an initial overnight charge (maybe even 15 to 18 hours) and cycle a time or two.

If it's a lithium ion pack, then it's pretty much a crapshoot. They pretty much begin to degrade as soon as they're made, regardless of charge state.

Anyway, leaving a lithium ion pack plugged in while you're on the cord (as in, the battery's good and charged, and you are running offa wall power) is a surefire way to premature death. They don't like to be continually topped off.

^ That's why it's a good idea to change your settings so it doesn't charge it to 100% but only 95% or so (at least while it's plugged in for long periods of time.) Just doing that can give you a huge increase in the life of your battery.

<danamania> so I gave it the electronic equivalent of a kick in the head, by shorting the +/- terminals for 5 minutes
<gelfie> don't they have stickers on them that say they could explode or catch fire by doing that?
<danamania> yeah but it's ok, I took them off first."

i thought i was the only one who took out his battery when it was charged...people always made fun of me (for this among other things), but the batteries of my last two laptops have kept nearly their full runtime over the course of two years each
