Battery Wont Keep Charging With 110 v

Question: We plugged the RV into a 110v outlet but the battery still looses the power. The battery doesn't keep its charge.

Robbie: It could be for a number of reasons:

If the batteries are hot they could be shorted and won't take a charge. They could have been dry of water or over 5 years old.

Check your Battery Condition Monitor when you're plugged into 110V and see if its showing charge. Take a reading at your battery terminals and it should be reading over 13 volts when charging. If not over 13 volts you may have a converter problem.

Remember one bad cell can cause the problem your having. Pick up a battery cell tester (Hydrometer) at any auto supply store (about $6) and check the water in each cell of the battery. Regardless of the reading they should all be reading the same after being charged 24 hrs. To totally charge a deep cycle battery takes 72 hrs. So your reading after 24 hrs of charging, if they were low when you started, would be about 1/3 in each cell.
