Subject: Batteries: Optima vs Gp 41...was Re: Group-41 deep cycle gel-cel battery -payback
Ron Lussier posted the specs to the Optima a couple of days ago, and the
full article is on his website at:
http://www.vanagon.com/beethoven/ele
ctrical.html
I tried to compare the two lists of specs side by side, but was not able to
interpret fully. It does seem that the Gp 41 is 1" shorter than the
Optima, so no cutting *might* be required to fit it in under the driver's
seat. I found the Optima battery online at a couple of places. Best price
was a plce called desertrat.com in Arizona [800.528.3402], $167.95 including
S/H delivered to CA.
Their website, http://desertrat.com/optimbat/optima.htm
has a good discussion w/ pictures of the Optima. The price is actually
$129.99. Shipping might differ to other places, and we are talking about
46.1 lbs.
Ron's post also had info wrt a trickle-charging system he used. He
suggested grinding off the top posts on the Optima, but James' suggestion
sounds like a good way to go.
FYI. I have no idea what might be the relative strengths/weaknesses of the
gel system vs the spiral wound technology.
Either of these could be a big help, and I appreciate everyone's input. The
timing is great, as I wanted to get some kind of auxiliary battery in place
in the next month, before a 12-day trip I have planned.
Love this list!
