Acceptable Battery Voltage with Charger?
Question:
My Grand Banks 42 is on shore power but the charge only ever goes to 12.8 VDC. Is this correct or should it be higher?
Answer:
With a smart battery charger, your batteries should be seeing a higher voltage than 12.8 VDC. At float, assuming the charger is NOT temperature-compensated and set to flooded, the voltage should be 13.3 VDC.
