He also said he knows driving every few weeks isn't always enough, which is absolutely true, as it can take hours to refill a cold lead acid battery so you slowly go downhill on charge.
With a healthy fully charged battery that is absolutely NOT true.
The self-discharge loss should be so small that a reasonable vehicle charging system can make up for 3 weeks worth in about 15 minutes......or less.
And trusting the onboard converter/controller to take care of the batteries over a long period of non-use is a mixed bag too. Some (many?) float them too high and tend to boil off the water, just like a cheap trickle charger. That kind tends to recover the charge slowly too. A good 2 or 3 stage controller, OTOH, will charge rapidly AND maintain the charge properly without excessive electrolyte loss.....like a smart tender type charger.
Specifics are needed. Generalities are almost always false and misleading.
