Well, it didn't blow up, but I think something is wrong with it or it's bogus. The first time I charged up the 1600mAH battery it only charged for about an hour and a half - it didn't really worry me cause I assumed it already had a partial charge. I played my DSL for maybe 4 hours (off and on) and red light... The DSL shut down about 30 minutes later while playing... I charged the battery and again it only charged for about an hour and a half... I unpluged it and repluged it and it stopped charging after a minute, so it must be full?
Anyhow, you're not supposed to get optimal use of a lion battery till you charge/discharge it 3 or so times, but it shouldn't be this bad. I iether have a defective one or it's junk. My original battery lasts way longer. I'm gonna proceed with a return/exchange and try another battery. I'm also gonna mail the manufacturer and see what they say.
I'll let you guys know and for now I put back in my original battery...
