Doing some research and admittedly I’m not very smart about this stuff, but I’m trying. I also looked at previous posts, but I didn’t see anything so here goes.
I have 4 lead acid 85AH batteries with a Progressive Dynamics converter/charger model PD9270 13.6 amps output.
I’ve read/heard you should change your controller to output 14.6 volts to completely charge the battery which I understand.
Now I have also have read that you can use one like I have, but it will only charge to 80%-85%, but may charge higher over a very long period of time. It also stated it would make the batter last even longer.
Looking for thoughts on this. Keep in mind, I’m not wanting to do major changes to the motorhome. Just wanting better batteries before my trip to Alaska. The 400AH lithium battery at 80% is far more then what I have now.
