Starting Batteries (Engine only!)

[Pete Masterson]

The engine batteries require maximum CCA when starting. The rest of the time, they don't provide much juice to the system. You should get regular type with high CCA rating batteries for the three type 31A 12v engine batteries. If you want the convenience of minimum maintenance, then AGM batteries would be preferred. If you don't mind doing regular battery water checks, then the Sam's CLub commercial type battery ought to work OK. At the moment, I can't tell you exactly what I have as the previous owner purchased them -- but they're Deka brand AGM, with 1000 CCA (more or less). They are not specifically a deep cycle battery. Deep cycle design reduces the relative CCA and what you need to start the Series 60 is plenty of CCA.

Personally, I prefer the easy (no) maintenance of AGM design batteries. I'd be inclined to get Sam's Club or Costco batteries for the reasonable price. Costco sells compatible batteries in both AGM and regular wet cells.

GROUP Question:

What batteries ("Deep Cycle" or "Regular Type/ with high CCA rating")

are best for "Start Engine/ assignment duty" would one go with when 

replacing all three (3)battery units.  <snip>

Would the Sam's Club "COMMERCIAL" type battery (@ $87.24 per battery 

cost)= "31A 12V @ 950 CCA" work just as well and replace them often 

as needed or would one invest into the "AGM type Deep Cycle" type 

batteries for the over all perforamce and longivity due to the 

various storage assignments of the coach and various charging issues 

(cyles, engine charging, shore power/inverter-charger, etc.)?????

WHAT WOULD YOU GO WITH when needing replacements?  I am sure 

the "ThermOil Battery Technology" was applied to the batteries to 

keep the corrision issue down in the battery compartment area vs. the 

AGM type batteries as used in "House battery Service"...
