Hello:
Over the past weekend I replaced our two house batteries (two 6-volt golf cart GC2). It looks like we got about 8 years out of the old ones, with light use. When I say light use, the batteries are usually kept at full capacity as we are either on the road or on shore power, not much rough camping. I thought with such light use we may have been able to get 10-12 years out of them.
While talking to the dealer where I bought the new batteries, he said that often times they only last a few years and that RVs by nature can be bad for batteries in that they tend to sit for a long time in storage (even if hooked up to a smart charger). I have read on this issue as well, and that it is good to "exercise" the battery occasionally, by draining it down to close to 50% of its capacity then charging back up. We have the Progressive Dynamics smart charger that is used when we are on shore power, and when in storage I hook up an external BatteryMinder with the desulfation mode. But I was curious if anybody knows of an external charger that can occasionally drain and recharge it when it's in storage and do the desulfation all in one. I've been looking and so far haven't found something for RV or automotive use.
I will post back if I find anything, just curious if anybody had looked in to this before.
