Hold, last til morning when sun starts charging again. It generally depletes at night. But occasionally I have to put a charge on it to avoid over discharge. But my question was answered. Dont keep fully charged. Let drain at night n what I thought. No charger on it all the time for battery...
I have 225w panels connected. I get maybe 15 to 20 ah solar. But I still drain battery occasionally so I wondered as easy n fast as the charger is, does keeping battery charger connected defeating the good.
