Does anybody have a recommendation on a good battery charger for maintaining high amp hour 12 volt AGM batteries?
I have 4 x 153 AH 12v AGM batteries that I want to put a maintenance charge on the while I finish building my solar system.
I just bought them, but they have been sitting idle for a few weeks and never put in service. The manual says they loose about 3% charge per month and should be charged with at least 20 amps.
I looked at the Optima1200 charger but from what I saw in the specs they were only rated for up to 130 AH batteries.
Ideally I would like to find a charger that the output voltage can be set manually so I can match it up to the manufactures specs rather than using a general all purpose setting. A digital readout would be nice too.
