Deep cycle or starter battery charging issues
I recenty moved from a class B to a small fiver. My old van had one deep cycle battery and I installed an isolator. This set up was good for several nights of light usage before I had to run the van t...

Thanks for all the great info.
I'm still trying to drill down to a better understanding with regards to MY :?specific desires....if they are acheivable.
On our first, and latest, trip with the new rig I figured my old deep cycle (and yes iit WAS a marine/starter battery) pooched so I got the ONLY deep cycle in the small town I was in to replace it. This is a new group 27 885 CCA marine/starter deepcycle.
This with a full charge only lasted a couple nights. My problem with accepting this is the years of performance experience with my old Class B that would let me dry camp for as much as a week between charges in conditions much the same as we had this fall with the fiver, namely 3-4 hours of lights, 1-2 furnace cycles in the morning, very little water pump usage per day. I can't see how the bigger fridge (running on propane) with electronic control (the old fridge did not use any 12 volt power at all) and a propane detector could make that much difference.
Also I'm concerned with the charge rate I can use to charge the batteries. The greater the charge amps the less time to recharge BUT I was told deep cycle batteries are best charged slowly.
I gather from the above posts that if I have more batteries given a set amount of useage they will each draw down less and therefore can be charged to full capacity faster, BUT if I use the same charger in both situations, given it has a set output, won't the resulting charge time be the same?????
Thank everyone for the help.
