I've seen some battery questions floating around here But haven't seen too much on the difference
between 6volt and 12volt house batteries.
I have 4 huge house batteries that I believe are 12volts each.
They are dated 3/08 SO I assume that I'm going to need to change them sooner then later.
When hooked to shore power OR driving down the road they (house batteries) do get charged.
I have to assume that the PO used campgrounds and didn't use the inverter very much most of the time.
I assume that's why he didn't replace them before I bought it, as the coach batteries are dated 5/15 so replaced recently.
My questions are:
Is there an advantage to using 6 volt vs. 12volt other then the weight savings you might get?
If I have 4 huge 12 volt batteries would I need 8 6volt batteries to replace the 4 I have now?
Is there a cost savings buying 6volts vs. 12volts?
Are AGM batteries worth the cost when the wet cell batteries have worked for the 15 years this coach has been alive?
Are the CCA's the same?
IF (at this time) I don't use the inverter - because I'm hooked to shore power OR can run the generator -
Do I really need to change the batteries that I have? They are NOT dead. I checked the water level on the 2 that I could get to
and they were at the proper levels and didn't need any added to them. There is a ground wire? hooked up that wouldn't
let me pull the tray out farther to check the other 2 and I didn't have tools to remove the wire, at that time so I assume
they might be OK too.
I had the vehicle hooked to shore power for about 5-6 weeks straight and just after Christmas I unplugged it to give them
a break from constantly charging. I plan to go back out (the MH is sitting outside in my backyard) soon and plug it back it as temps
here are in the teen's for highs and single digits overnight, so I assume charging them will help keep them from freezing, right?
Also I flipped the disconnect switch for the house so no energy should be being used - but left the chassis batteries on so the step
will still work if I want to get inside it. SO If the switch is flipped do the house batteries still get charged when on shore power?
Would any of the answers you plan on giving change if adding solar panels in the future was a possibility?
It's too early (for me) to tell if I will be doing that to this coach down the road or not. I doubt it would be before 3-5 years are up.
Thanks for any info you can send my way.
