Could anyone tell me if a deep cycle battery MCA 750 compares to a car battery of 825CA?

 

Will 2 2 deep cycles do as a good job as 2 car batteries?

 

I own an RV with a Cummins 400HP.

Are these to be used as starting (chassis) or house (where deep cycle is important)?

They will be used as chassis batteries.

 

 I know that deep cycles are made for house batteries but if I install deep cycle 750mca will they turn the engine as well as 800ca auto batteries.

All other things being equal, 800 CA batteries (assume at least a pair) will be slightly better than 750 CA batteries.

 

But, Cummins is your source for battery requirements to start our ISL.

 

Much of the equation will depend on what the coldest temperatures you will encounter (and need to start the engine). Another question will be if you will have a block heater available under these lower temperatures.

Again the question-- for engine starting batteries (chassis batteries) or house batteries (where deep cycle are superior)?
