This page aims to distill the knowledge contained in HandyBob's RV battery charging puzzle 2 page.
Particularly useful and pithy statements are quoted directly.
HandyBob and his wife are fulltimers in a 5th wheel and have no generator. He prefers quiet and and wants folks to stop using generators, or at least use them more considerately.
“Batteries are not sponges that soak up amps. They are a lot more like tires that need to be filled up with air pressure. You need volts (pressure) to get the amps (volume) to go into the battery… Batteries self regulate the amps they will accept depending on level of charge and voltage. The amps going in will drop as the battery fills, and if the voltage is not high enough the battery will not be charged all the way up before the amps taper off.” – HandyBob
