wow heres a twist in the story. After hearing about ur different batch numbers i went and double checked mine. Turns out that most of them are batch 025...i found a few batch 018 and heres the kicker..one batch 001, which expired in 2001. I guess i looked at 1 amp in the beggining and assumed that they were all the same. And theres no telling how many batch 001's ive used or even how many my training partner has in his possession or used. Thats pretty ****ed up to sell someone expired gear.

Lesson learned though...check EVERYTHING.
