[RE-wrenches] FullRiver battery question

[Ray]

I don't see why it wouldn't have similar performance to other Fullriver 
products.  The problem I've had in the past, when I found that "perfect" 
battery model on the spec sheet, is that the distributor usually doesn't 
stock it, and then it either is too pricey, or too long a lead time to 
be practical.
