Hi,
The battery is three years old. Yes, I checked the battery water and all cells were full. This is a 2007 camper but the newest one I've had til now was a 1987 so I was not aware that shore power would charge my battery. HOWEVER, I disconnected the power cord from the battery charger and used it for my "shore power". IF the battery was bad, do you think that might have caused the problem?
The battery did have enough charge to power my 12v lights but not enough to power my new LED replacement bulbs.
Thanks for any incite.
