I have a 1000 amp hour 12 volt AGM battery
bank on my boat made up four 8D Lifelines
. They are 8 years old now and beginning to lose some capacity. They've not been worked hard, very seldom discharged below 12.3 and, due to the recession, have spent most of their time at float (13.2-13.3). Now I'm advised I need to replace them, a two to two point five boat unit expense.
These batterys have never been equalized because I've always assumed one does not equalize AGM's (can't add water). Some say a good equalization
would extend their life for a year or so.
So, I called Lifeline. They RECOMMEND equalization
@ 15.5 volts. No amperage value given. About five hours ballpark.
That's a lot of non specific information to my way of thinking.
So I asked if they had a recommendation on a brand of charger
to use to get a constant 15.5 volts for five hours. "Use your inverter/charger's equalization mode" I was told. Well, I burned up a perfectly good pair of golf cart (flooded) batterys once using an inverter/charger so I'm a bit hesitant.
I use Outbacks for my inverter/chargers (stacked units), and I think they are good equipment
but I'd still rather have a dedicated charger
. Anybody know where I can get one.....or am I just being paranoid.
Any advice would be appreciated.
