Coach Batteries: Do I Need More Than One?

Recommended Posts

When we bought our motorhome (used) from a dealer, it came with only one coach battery. We have been told that we should get the two other batteries because that is what it has room for, and if we don't, then things will not work as they should.

Any help with this question will be appreciated.

As long as the battery (or batteries) are kept charged (12.2 VDC is as low as you want to run them), it does not matter.

More batteries allow you to run your coach 12 VDC house systems longer before having to recharge them. If you stay plugged in when not driving, not an issue.

If you dry camp, more batteries (more amp-hrs) is very important.

Deep cycle is good for house batteries but a pair of 6V batteries is not necessary if you have 1 - 12V battery that suits your current needs.
