Deep cycle batteries

[dilbert]

Dilbert:
They say 2-3 years..

If yu wanna know if it takes a charge, take it to the nearest auto shop (any of the small shops connected to gas stations) and take the battery over there and ask them if it holds a charge...I've done it with a bunch of batteries and it's been free everytime....

I took it to two auto parts stores and they told me that they couldn't test deep cycle batteries. Napa was closed, I may give them a try next. It seems to be holding a charge fine now though...I may give it one more try on the water.
