I had the starting battery come up dead on me yesterday when I went
out on the river. I will replace it of course, but I figured I
wanted to replace my trolling motor batteries at the same time.

My partner for ABA (Hammer) uses a battery in his boat that is
lighter than a regular battery for its size. I think it is made by
Interstate. Does anybody know what battery that is?

Now, the hard question. Does anybody know of a better battery that is
lighter for the capacity?

I do not like Interstate. I used to use their gell cells for my alarm
company, and they were the worst batteries with the highest failure
rate of any battery I have used. I have also had a pretty high
failure rate / short service life with their batteries in my service
trucks.

What about these Bob?
