A Friend and I were discussing laptops, in particular Apple Powerbooks. He recently acquired a Powerbook from his work, plus he has an old G4 under his desk, used as a server. He usually has insightful comments, so we often have conversations about this and that new geek gadget. During the discussion we started talking about battery life and the best way to charge. I purchased a R30 for my brother two years ago with an additional Ultrabay battery. It still often gets 8+ hours of hard office-type use running WinXP. Every comment I’ve read and my experience has show that IBM hardware kit just works. This should be the inspiring goal for any laptop battery system. Although following the “Conservation of Greatness” rule, I’ve been told the IBM’s service often sucks. Luckily I’ve never had to deal with them.
Anyway we started discussing batteries, and how to best care for your battery. Based on a page I’d read several years ago I’d always been of the opinion with Lithium Ion batteries, that constant charging is a good thing to do. This page had stated that Li-Ion batteries have a finite number of ‘deep’ discharge cycles. Thus it was better to keep the battery charge to preventing the ‘deep’ discharge cycles occurring.
Richard’s opinion was the opposite of this:
“Nah I got into talking with a laptop guy on this one, and it’s the continuous connected to the mains stuff that destroys them. Doesn’t matter the battery type, if it’s continuously trickle charged it will die.”
I figured it was time to do some goggling.
