View Full Version : Need an advice in Laptop battery care

24-12-2008, 02:45 AM
Hello Wise Friends,

I have gotten a nice Toshiba Satellite p305-S8832 with a 4000mAh Lithium Ion battery pack that usually lasts 2.5 hours.

My question has to do with the fact that the most of the time I use my lap top as Desktop replacement at home and plugged to an UPS. I removed the battery. What would be the best way to keep my battery in good shape, should I simply store it with some little charge?, should I use it normally once in a while? I know that Toshiba laptops have not smart charging system and the battery might be damaged if it is overcharged.

I will appreciate your so kind and wise advice. Merry Christmas and a Happy New Year to each and every one of you.

Keep it plugged in with the battery, but every 2 months or so discharge it right down to 0%.

Merry Christmas to you too emmerc! :)

Lithium Ion btys should NOT be discharged to 0%. This will kill a Li ion bty. In any event, they contain circuitry to control charge and discharge levels. If they didn't, there would be many go up in violent flames. They are darned dangerous things hence the tight control necessary.

You should get Toshiba's recommendation but partial charge and occasional recharge would likely be fine. Don't forget the power of Google!
