Coach batteries

[rfsod48]

I need to replace my coach batteries. 95% of the time we are hooked up to shore power. Currently we have 6 6v batteries which are wet cell. With our limited use would it be best to stick with this type of battery or would it be better to go to AGM type?

I was thinking the same. 95% of my nights are connected to shore power and two 6 VDC batteries are more than adequate. I'm wondering if the count includes engine start batteries also which would be more in keeping with a typical configuration. 2 chassis, 4 coach. I would stick with wet cell. AGM are very good batteries but unless your travels have you off the grid, a lot, the added cost would be better used for fuel and CG fees.

From what you described, 2 - 6 volt batteries would be more than adequate for your needs. Unless by chance you have an all electric refrigerator??? Having said that, 4 - 6 volt batteries would be more than adequate...that is what the majority of MH's have.

When going down the road, your batteries are being charged continuously by your engine alternator.
Decent AGM's will cost about $200 each and are probably not needed unless you like the zero maintenance aspect. If you still want to use AGM's, as suggested, go with four instead of six batteries.

Normally we only use battery power in rest stops or going down the road. So you feel it would be feasible to go to 4 6v instead of 6.

The AGM vs wet cell has less to do with capacity than with the trade-off of no maintenance vs cost.

And, if you don't dry camp, there is no need for that large a battery bank-- irrespective of whether you go with wet cell or AGM.

Said another way, 4 golf cart batteries (around 440 amp-hrs @ 12 VDC)would be ample for the way you use your coach. Save the money and weight.

I forgot to include that we have a 2005 Fleetwood Bounder with Catipillar C7.
