As batteries age and are used, the plates inside become coated with sulphation.
When this develops, they lose capacity to crank the generator even though they may show over 13 volts while plugged into shore power or after charging with a car charger. Our two T-105 6-volt golf cart batteries lasted around 10 years, I replaced them with equivalent cheaper US brand batteries and replaced the original converter/charger with a modern Progressive Dynamics 45 amp multi-level charger which won't overcharge batteries and boil out electrolyte.
RV batteries that are not kept charged and electrolyte levels checked and maintained don't last as long as those that are.
