First dry camping trip, Magnum question

Folks,
Have a MSW 2000Watt Magnum setup in my AC Revolution. Has 4 new costco GC batteries.

I was suprised how long it took for my Genny to recharge my batteries in morning/evening. Notice my bulk charge rate was ~80A. Then with research that may actually be too high! That 1/10*C is the preferred rate for wet cells. That would equate to 44A?

How do folks have their Magnum's set up? I assumed I could run my gen for an hour to charge batteries but that wouldn't get them even close to charged, and if I depleted them to 50% then at 44A charge current it could take 5 hours?!?!?!!?!?!!!!!!

We run our res. fridge and fans at night....

Thanks for help/advice,
Chris

Your best bet is to call Magnum....tell them what batteries you have and they will walk you through the settings. Our previous coach and current coach only take about two hours to bring back to full charge after refer and TV watching.

If you have a res fridge, you can make it overnight with it completely shut off. These things are great at holding temperature

Go to www.magnumenergy.com
Look up the owners manual for your unit.
If the batteries are at 50% SOC 21.2 volts it will take at least 4hrs. to bring then to a full float charged state.
