If using a portable charger, aim for anything over 10 amps but running a generator, it will be costly. A 40 amp charger would be better.pianotuna wrote:
How were you deciding the battery was fully charged?
The 12V charger on 2 amps for overnight left battery at 13.1 V
The battery (swapped over ) will crank my big truck no problem.
Battery was new July 2017 and was kept charged although on my 3-4 day trip it discharged each day, so we ran the portable generator all day to recharge that battery ( disconnected ) to bring battery back. Soon as hooked up to terminals heavy discharge. Again this battery maintained since July 2017
Kept on a floating charger , So my guess is battery good -
You have multiple problems that I can see. Perhaps a large draw on the battery but also, an inefficient charging regimen.
If you are only adding in 20 amp hours/day, you will constantly have a severely discharged battery and that will lead to a loss of capacity, quickly. A typical lead acid battery should only be drawn down to half of it's capacity. A marine hybrid battery will withstand a dozen of these cycles with a small capacity loss. A conventional lead acid car battery won't withstand a dozen and will be worthless. A good deep cycle battery may withstand more than a dozen full discharges but will still lose capacity.
