AGM Battery Question

All Golf batteries are made to deep cycle while you cruise the 18 holes.
No starting involved.

Are 6 volt, deep cycle - non marine flooded batteries really available?

I havne't done an exhaustive search yet, but will do so by Spring. Right now my rig is sitting outside without any house batteries. The chassis battery is doing OK, but it's an easier thing to replace.

The answer is yes. Most RVers use 6 volt flooded golf cart batteries.

Here's a good article on AGMs. They need a different charger than an ordinary 12 V charger to make them last. The chargers I have used on AC batteries were expensive so I don't care for the batteries Though they are great in Airplanes and boats. Deep cycle marine batteries have a better clearance between the lead plates and the bottom of the battery. When a lead acid battery becomes discharged both electrodes undergo chemical changes to form lead sulphate and eventually the battery dies from buildup on the floor or bottom of the battery which causes it to touch the lead plates.

Yes. Almost every manufacturer makes them.

I have 3 Concord marine deep cycle 8D AGM batteries in the motorhome. 158 lbs. each.
Take a look at Interstate. The SCS series is marine deep cycle, used for trolling motors. The BCI series is marine deep cycle/starting.

Do a search for trolling motor batteries. Almost every manufacturer makes them. Some are designated as marine, some are not.

Cabelas sells bateries that are labeled marine/RV. Not sure who they are made by, never checked.

Did you read my second post? Thought I explained the two types quite clearly. Deep cycle and deep cycle/staritng. Two different animals.

Not all marine deep cycles are dual purpose. They are engineered for totaly different purposes.
One is a "true" deep cycle engineered for trolling motor use and is used by most tournament or avid fishermen.
The marine deep cycle/starting battery is used not only as a starting battery, but power the electronics, ie. fish locators, lights, depth sounders, live well pumps etc.
The internal construction of a marine battery is quite different than a standard deep cycle and is not needed in an RV, plus they are more expensive.

Harold, I both agree and disagree.
The Trolling battery is a true deep cycle, it is labeled Trolling OR Deep cycle

The Marine/Deep cycle is the Dual Purpose primarily starting battery

I HAVE LOOKED for trolling batteries, yet to find 'em.

I have however found Deep Cycle FLA's in many sizes. Including a couple you do not want to put in your motor home (Cause they are too heavy)

Sure, golf cart batteries for example.

Thanks for all of the replies.
Now I have a better idea about what to look for when replacing house batteries.
