In the Spring of 2006, we bought two Group 27 deep cycle batteries from
Walmart.....approx. $85 each.....they lasted two seasons....wouldn't
hold a charge.
In the Spring of 2008, we bought two Group 27 deep cycle batteries from
a dedicated battery shop here......they were Great Northern
batteries....I believe made in the USA.
When we were taking the Walmart batteries off the boat and replacing
with the Great Northern, I weighed each battery on a bathroom
scale.....the Walmart battery weighed approx. 40 lbs each.......the
Great Northern battery weighed 55 lbs each.
The Great Northern batteries have now seen 7 seasons and appear to be
fine even after I abused them (two seasons ago I let the electrolyte get
so low as to expose the top of the lead plates for some time). Topped
them up with distilled water and charged them for about 6 hours at 6
amps and then another 20 hours at 2 amps. That brought the 'specific
gravity' back up to approx. 1.65. Until we see any signs that these
batteries can't hold a charge, they will stay on the boat.
As a back up, we carry a rechargeable Canadian Tire portable 12 V - 120
V battery with an inverter in case our Group 27's fail to start the
engine. The Canadian Tire battery weighs approx. 11 lbs.

I have 3 Scams Club deep cycle batteries, This is my 6th year and they are
still fine, but I think like you say I will replace next spring on general
principles. This year they (Sam's) say Duracell I think. But they are
probably still Johnson Control. Like someone said, weight is probably a key
element. Along with lead, of course.

Wal,
What you say is perfectly true, but...
There are deminishingly few battery manufacturers in the US because of the
impacts of environmental and OSHA regulations. And for the past decade or so
Walmart batteries have been made by Globe Battery Div of Johnson Controls.
They also make batteries for Interstate, NAPA, and the Sears Die Hard, among
others.
Walmart and Sam's Club offer very good pricing, the lowest in my area, and
good quality. The 115AH group 27 deep cycle batteries in my 38 were
installed in 2006 and are still going strong. ( the batteries in my 25 were
bought in 2003 and may need to be replaced soon on general principles) They
were rated at 25AH more than the 27 deep cycles from West Marine, and cost
less than half as much. Plus they had a 5 year warranty instead of 12
months.
My experience with deep cycle batteries from Walmart has been very good, and
I have no qualms about recommending them.

And I don't want to sound cynical, but WalMart doesn't manufacture
anything. With the purchasing power that they have, they can dictate terms
to any supplier. And they do. The battery that you get from WalMart or
Sam's Club this year can be entirely different from the battery you'll get
next year. It might look the same and have the same label...

Consumer Reports rated the Walmart batteries very highly.
