Battery Advice

Time to buy coach batteries from Les Schwab here in the northwest.

Here are the options,two Group 27's @ 120ah a piece which would make 240ah.The cost 110.00 a piece.

Two golf cart batteries @220ah a piece which would make 220ah in series with the option of adding two more later the cost 96.00 a piece

Thanks

Hi ftv37,
For coach batteries, go with the golf car batteries in series.

Second vote for the golf cart batteries

But they should be not more than $65.00 each
Try Costco - Les Schwab is great for tires but their prices on Batteries is too high for the very same thing you will find at Costco up here in the North west

Unless the G-27's are true deep cycle, I second the first reply, go with the Golf Car batteries.

NOTE: when you put a pair of six volt GC batteries in series,, Treat the pair as ONE SINGLE 12 volt battery.. For all operations (Save lugging it to/from the motor home) it is ONE SINGLE 12 volt battery.

You buying them online? Where is to buy batteries for best price

Those gp 27 12V batteries must be a cheap version. WalMart has 12V deep-cycle batteries with 190AH.

how much?

The problem with the Group 24 or 27 batteries is that most are not true Deep Cycle in the true sense. For that reason the Golf Cart Bats are probably the best choice as they are truely designed for heavy duty use.

I found some interstate batteries I may go with.

That can't be the 20 hr rate, must be the reserve capacity

[adehaan86]

What's that mean?

There always a chance I'm wrong. I think WM calls it a Maxx deep cycle battery G29. I can't even find batteries on the WM website.FWIW, Exide makes a 12V deep-cycle battery especially for off-grid solar systems that has a 200AH rating.

Yep...two 6 volt batteries in series doubles the volts; however the amps are that of a single battery....220 a/h here.

2 pairs of 6 volts in series/parallel would get your 12 volts and double the amp hours as the parallel doubles your amps to 440 a/h.

All of this is based upon using 2 or 4 220 a/h batteries. Good luck!

Remember to have your charger set at 14.8 for either trojan or interstate non-AGM batteries to ensure you're getting a full charge.

I have 4 WalMart Maxx 29 batteries. They are labeled "marine - deep cycle". I have used them for two years. My advice, stay away from WalMart batteries. They are not "deep cycle" and two have lasted longer than the warrienty. I'll be changing to 4 6v golf cart types probably Trojans or Interstate this summer. With Walmart - you do not get value for what you spend and you are your own warrienty.
