Get a Group 31 Odyssey AGM battery. No maintenance, incredible
cranking power and much smaller size. I replaced 8D's on my Detroits
with these and the engine just spins.

For those that get Powerboat Reports, they recently tested some Group
27 / 341 size AGM/Gell Batteries.
They really liked those made by Mastervolt and Trojan.

Lee,
It seems one has to be a subscriber to read this report. Any chance you
could post a summary of the top three of four batteries they liked and
why, by brand and model number?
Trojan makes several models and when we looked up the new 6V AGM golf
cart battery we were surprised to see that it is listed as a mixed duty
(starting/medium discharge), as opposed to a traction battery.
Our T-105s have given up the ghost and we are toying with the idea of
replacing them with AGMs. We'd put in Optima in a minute, but they are
hellishly expensive down under.
Cheers,
Maurice & Louise-Ann

PBR did a deep-cycle test, by drawing the batteries down with a bank of
light bulbs big enough to add up to their "20-hour" amp rate. Those
that lasted the longest were highest rated.
They liked the new Trojan group 27 AGM as their best buy, and the
Mastervolt group 31 AGM. They put Lifeline group 27 AGM in third place.
They didn't get as good results with the Deka g27 AGM (which rather
surprises me, as my house bank g31 Deka AGM's have performed wonderfully).
They were much impressed with the Trojan's reserve capacity as tested.
It looked really good for a group 27 (although its weight is more like a
group 31). They said if they were building a high-capacity multiple
battery bank for the longest cycle life, Mastervolt would be their
hands-down choice.
For some reason they had a mix of group 27 and group 31 AGM's in their
test, and 27 and 31 Gel's as well. When I've researched batteries, I've
found that the characteristics of a particular manufacturer's g27 and
g31 batteries are often more different than the size difference alone
would suggest. Seems to me a test of like sizes would make more sense.
In adition to six 27 or 31 AGM's, and three 27 or 31 gels, they also
threw an Optima yellow-top into the test. Because of its low AH
capacity per pound, the yellow-top isn't really very comparable to the
other deep cycle batteries in the test. Both blue-top and yellow-top
"deep cycle" Optimas might be better described as "dual purpose". I
sure wouldn't choose an Optima for a real deep cycle application, though
I've been quite pleased with their starting batteries.
PBR also said that Optima red-tops were for starting, yellow-tops for
automotive deep cycle, and blue-tops for marine deep cycle. In fact,
blues come in both deep cycle and starting varietes.
Maybe the Trojan 6V GC AGM is thought of as "mixed duty" because its
specs on their web site indicate much higher cranking amps than other 6V
GC's I've seen. Their AH rating (200) is pretty deep-cycle-ish, but a
bit lower than that of the flooded T105's (225).

Richard,
Thanks a bunch...most useful.
Re the Optimas, I agree they are good start batteries. I also think
they are ideal for thrusters. My liking for them in deep cycle use is
based on those installed in a friend's sailboat. He put in some of the
original optima STARTING batteries (dealer did not recommend going for
the deep cycle ones due to price). When we last saw him, these
batteries were still going strong despite several years of deep cycle
use on a daily basis (he's sailing around the world in a small
sailboat). He abuses those batteries and when I talked to him they were
showing no sign of degradation.
Cheers,
Maurice
