battery problems

September 26, 2012, 12:46:29 am

I have a 1993 cc Magna. My husband and I bought it 1 year before he died and I have maintained it as best as I could. It drives like a dream and it is a beauty inside for her age. I keep it hooked up to power year round. my problem is the batteries boil over. in 2010 i replaced them all. in 2011 they said i had a bad battery so I replaced that one. Now they tell me the problem is i have another bad battery. I have stated to them the problem and that it must be the motor home that is causing the batteries to go bad. I have to replace the fluid and clean off the batteries once a month. It has gotten so bad that i have had to start it every 2 weeks to charge the batteries, even though it is hooked up to power all the time. Anyone with any advise, i sure would appreciate the help.

I'm not familiar with your coach, but I'll take a stab at it. I think boiling batteries is caused by overcharging by the converter side of the inverter/converter. This could merrily be a wrong setting on your inverter/converter control panel. Many coaches do not charge the engine battery when plugged in, so assuming yours doesn't, then the overcharged/boiling batteries must be your house batteries.
The overcharging issue must be isolated before spending money on more house batteries.
For the engine battery not being charged while plugged in, you might have a defective "echo" charger or no engine battery charger was installed by CC? This is not the same charger as the one for the house batteries. If there is an echo-type charger on your coach for your engine batteries, then try getting it fixed. It could be just a fuse. If not, there are after market echo-type chargers that can be installed.
