RE: Duralite vs Powerflite?
I wouldn't be so quick to buy Duralite.
I invested over $1000 for the Duralite batteries, which turn out to be, used ones with expiration date under the shrink rap. Then they came with the Duralite Plus. Who is to say that they are not the same scheme? They where willing to give you some replacement value, why not replace them all with the new ones if you lied the first time.
