What is the make and model of your charging system? 13.9 VDC is about right on the charging voltage, but not if that is constant. It should taper down to barely 13 VDC when the batteries are fully charged. If they are dropping down that fast then either they are failing OR you have a drain on them. If you have a small digital meter (and it appears you do) then we can test for this. Most places that sell batteries can load test them for you. Batteries usually last about 3 years on most RV applications. Get back to me with this information and I can assist you further here. All follow ups are included in our fee. No time limit.
