Using a multimeter across the battery terminal is a great way to determine if they are being charged. The normal fully charged DC VOLTAGE of 12.6-7VDC will show an increase of 13.2. or 13.6VDC when being charged. Certainly takes the guessing out of the procedure using a multimeter...
We watch our batteries like a hawk when using them and when in storage as they are just too expensive for me to not do this...
