Replacement Batteries

[Pka5528]

Plans are to buy two batteries for my 2007 Outlaw. I have read on the post about 6 volt Concorde brand batteries. Is this the best way to go? I purchased the Outlaw earlier this year and have know idea how old the batteries are. Any advice?

I do not know about Concord batteries...
I would have your current batteries checked. They might be good for several years.

I like the 6v golf cart batteries. I have a Napa brand that seemed to be cheeper than some of the others. For house batteries, getting deep cycle is the most important factor. You should only use them to about 50%, so get twice as much amp hours as you will need.

Concorde are premium batteries...see: Lifeline Batteries - Marine & RV Deep Cycle AGM Batteries
They make models for aviation and military applications...see: Concorde Battery - Aircraft Batteries

You can't do much better than that, and I would expect they are pricey.

But first, are you asking if 2, 6Volts are better than 1-2, 12volt batteries for the house battery bank?

The answer is YES. And the Outlaw's house battery tray is made for 2 standard size 6volt deep cycle RV/Boat/Golf Cart batteries. I got my last new one at Costco.

Best luck

First there are basically 3 classes of battery
Starting, Marine/Deep cycle (Also a starting) True Deep Cycle/Golf Car (What you want)

Now. Thanks to golf car companies like EZ-GO and Yahama it is getting easier to find 12 volt GOLF CAR batteries (DEEP CYCLE)

But it is still a fact that for 6 volt golf car battery is the single most produced deep cycle battery out there. and thus the lowest cost per amp hour.

I bought my last two 6V Golf cart batteries at Costco two years ago @ $80 each. So far they have been good.

1. There are both combo deep/cycle starting batteries AND pure deep cycle batteries available in 12volt. You do NOT have to go to 6V to get true deep cycle as previously stated.
2. I do NOT recommend going to a dual 6V battery plan IF you are only going to use 2 batteries for the simple reason of redundancy. If you add 2 12V group 27 or 31 batteries you have similar amp hours to the dual 6V battery set up.
But if ONE 6V battery fails...you are without a house battery system. If one 12V battery fails...you still have one to use. I AM a fan of 6V batteries when used in groups of 4 as they provide a lot of amp hours for the $$.
3. There is NO reason to go to the extra expense (more than 2x) of AGM concorde lifelines vs. standard wet deep cycle batteries unless your use pattern and convenience desires outweighs the price differential.
4. No reason to throw away your existing batteries until they are near the end of life. Suggest you fully charge them overnight. Then disconnect them from the coach (remove negative wire) and wait 12-24 hours. Don't shortcut this step!! Then put a volt meter on them. If the voltmeter reads 12.5-12.7 you are in good shape...spend your $$ elsewhere for now. 12.3-12.4 ....getting weak...showing age but still serviceable. 12.2 or less...time for new ones.
Alternatively, if you have wet cell batteries now, you can get a turkey baster and take direct readings from each cell several hours after last charge.

Hydrometer reading of <1.210 specific gravity means replace. Test each cell.

I had interstate deep cell and start batteries in my MH for 11 years with no issues. I replaced them due to age and brought interstates again.

Just put in 2 Everstart Maxx Group Size 29 Marine Deep Cycle Batteries to replace my Coach batts. Bought from Walmart for $99.97 ea.
