Losing my mind with Battery problems

[xkelly]

Hi,

I have a T21. Battery Max Miser has been showing my main battery health in the yellow. I've tried recycling it by bringing it up to a full charge (Lion), then draining it completely. All shut down times disabled and such. When I recharged, I checked the health. It was the same. So I bought a brand new main battery. The battery health on the new batter also read as yellow. I just recycled it and now it's RED! I have an ultrabay battery that is in the green with out any problem. What is going on here? Any help would be appreciated.

Thanks.

You may have found this out by now through reading other posts, but recycling/fully discharging Lion batteries actually degrades battery health. I'm guessing that this is what happened. Unlike older NC batteries, for Lion batteries, multiple shallow discharges are usually better than a deep discharge.

Thanks for your reply, William. I didn't know that about Lion. It was the MaxMiser Help where I got the tip to do a full drain. I won't be doing that again anytime soon.

Since the battery came out of the box yellow, the online seller is sending me another, no questions. I just have to return the first one. Pretty fair. I hope this one is green.
