T2? Battery - FRU 02K6627 vs FRU 02k6626

[stevech]

Does anybody happen to know what is the difference (if any), between the 2 battery FRUs?

I picked up a used T21 recently, it came with 3 batteries, the seller pointed out that the one battery he uses all the time is good, but the other two have not been used for a long time, and are status unknown.

Sure enough, I have one good battery, and two that do not hardly hold any charge. All three are in cosmetically impecable shape. The 2 things that I notice are the working battery is an FRU 02k6626, the two that do not hold charges are both FRU 02k6627. Also, the two non working one do not have the little silver sticker on the side (VOID WARRANTY IF REMOVED).

I did not pay extra for these battery, but am curious, and as they look brand new, I am hoping there may be a way to rejuvenate them.
