I have a 2014 Hawk with the original 12v AGM lead-acid battery that FWC installed in the camper when new. The charging system is the stock system with the battery monitor that FWC used at that time. I keep the camper plugged into shore power at all times when the camper is not in use.
On a recent trip the battery monitor showed 2/3 charge when in past it had always showed full charge. When I returned home I checked the battery with volt meter and measured resting voltage at 12.1v and with the water pump running and the 3-way refrigerator on the 12v source I measured 11.8v.
My question - is it time to replace the nine-year old battery? If so, what type and where is a good place to purchase one?
To be clear, I understand that there are a number of improvements I can make to the basic FWC installed electrical system. However, I don't use much power and typically drive the truck every day when camping which recharges the battery. The current system has always met my needs and I figure if it ain't broke, don't fix it.
Appreciate everyone's input.
