I've noticed that there are at least two different types of BST-37 batteries. The older ones (R1A) say "Made in Korea Finished in China" while the newer ones (R1B) say "Made in China Finished in China".
The older ones charge to 100% and stay fully charged much longer than the newer ones. The later drop to 98-97% as soon as you unplug the charger.
Has anyone else notice this ?

i have exactly the same as the 2nd battery although R1A(different serial numbers of course), Made in China Finished in China with 05w28 date...after 7months of use i still manage 100% from charging and still maintains 4-5days of use before charging again. The best battery i have ever had in a mobile phone(next to the t39m's). The first one looks rather strange, it seems that it's covered with sticker(the back) as i recall seeing alot of the 2nd one that's plainly out of metal.
