I am purchasing a new Group 27 deep cycle battery and will be checking out
the place Bassy suggested. Our boat does not have a high electrical demand
(depth finder, marine radio, stereo) when not running.

What are some of the specs I should be looking for to show it is a decent
battery?

TIA!

I'm interested too!
My demands are even less, as I don't have electric start to worry about.
I'd need navigation/cabin lights, depth sounder & later, a hard wired
VHF. (will use handheld for this year) I also want to be able to
run/re-charge my GPS and handheld VHF from a cigar type lighter outlet.

One good measure of quality is weight. The heavier the better.

Are the weights of batteries normally included in the specs?

I would guess that by more weight you are referring to heavier lead
plates....correct? How does that translate into more cranking amps or
ability to hold a charge and deliver power over an extended period?

Thanks!

I don't know. You could pick up a few. The weight differences are really
noticible.

If you want cranking amps you want more plates. Deep cycle batteries have
fewer/thicker plates. I'm not really sure how ampere hours come about. I
would guess that physical size matters in that case.

Pull up one of the battery maker web sites if you want an education on
batteries. I would recommend "Surrette Battery Company".

I don't plan on carrying a scale with me when I look for batteries. ;-)

I am sure there have to be some significant specs I can compare such as
cranking amps and ................

Does anyone else out there know?

I bought the top of the line Group 27 deep cycle ($79) last week from the
place Bassy recommended (Batteries Plus). It weighs a ton, especially
compared to the Group 24 starting battery I purchased earlier this year from
West Marine.

I guess weight is indeed a factor with quality.

Thanks for your help Jim.

You are welcome. Happy boating this season.

Check out a Group 31. Often they will fit in the same box and give you
more amphours for the same or a little more money. I have found good
batteries and deal at Sam's Club/Walmart.
