Thermoil ?

[whisker]

Wondering if anyone uses this stuff in their deep cycles? Is it any good?
Welcome to Thermoil Inc.!
AND...does anyone use Optima closed cells....are they worth the extra $$$?

I'd be interested also. I know the guys at A-1 Marketing, the distributor for this area, I'll give them a call and see what I can find out.

I recommend either the yellow top or the blue top. The only difference I see is the stainless posts for boat implements, but you can put your own on a yellow top. I have the yellow, and love it. 2 1/2 hours and they are a lot lighter than most batteries, which is a plus.
