Confusion on battery charging
I am confused about the best practices for charging batteries. For 7 years I had 300 AH of Lifeline AGM batteries, 270 watts of solar and a simple charging system. My old camper has a 110 volt c...

I looked up the MegaWatt unit. It is just a cheap 120 to 12 volt charge controller. I think I would spend more and get an automatic 3 stage charger. Anyway I am traveling and do not have that option.
I fail to see what is unreasonable about using solar panels. I think I should be able to fully charge my batteries when I am at 90% charge and have sufficient amperage to maintain the absorption charge for close to an entire day. That would be no different than setting the MegaWatt or other charger to absorption and powering it with a generator all day.
It just seems that something is wrong when a full day of charging on almost full batteries never achieves the standard for a full charge.
