Coach Battery

I didn't have space for two. Just bought a deep cycle at batteries+ for about $200 based on what I'd understood from previous conversations here. I think it was this one: https://www.batteriesplus.com/productdetails/sli24magmdc

Looking at the brochure for your coach I see they refer to "the battery". I would be curious to see the actual battery area and see if there was room to have another batter carrier installed and then throw 2 Trojan 6 volt deep cycles in there. I upgraded to them and the difference is remarkable.

Cruisee,

If there is any way you can fit a pair of GC2s in that house battery space, do that.

If you aren't sure, find some boxes and packing tape and make some. We did a lot of boat electrics before the depression, and I used to keep a pair of cardboard (much lighter than the real thing) in the coach just to used for show to owners.

The other thing to be aware of is that 12V real deep cycle batteries are both rare and expensive. Marine batteries are not. CCA and CA can have little to do with actual capacity. If there is no Amp-Hour number available, look at the Reserve Capacity. That is the number of minutes you can leave the headlights on and still hole to start. This is a real number.

The larger cold cranking amps may also indicate more amp. hours. I do pay attention to cold cranking amps, as my house battery also starts my generator.

CCA is important for chassis batteries - amp hours is what you focus on for the coach battery.

Some Class C RV mfg provide a single class 24 battery which maybe insufficient depending on how you use your RV. Many add a second battery. You can always get a bigger battery upgrading to type 27 or type 31 battery if space is available. Once again the focus is amp hours which might be 80 in type 24 increasing to 125 in type 31. Some replace the 12 volt batteries with two six volt deep cycle batteries which might provide 225 amp hours. In my case space (height) was an issue so my Class C has two type 24 which I purchase at Costco.

Do you have room for two batteries? If so, two 6 volt golf cart batteries wired in series to give 12 volts will serve you much better. There are virtually no 12 volt wet cell batteries that are truly deep cycle. Don’t go by CCA when selecting a deep cycle battery. Amp Hours is what you want to use as comparison. Frankly I’m surprised there is only one coach batttery in an RV your size.
