Noticed yesterday after my Travel Trailer battery would not charge on the trickle charger for more than 3 days, the battery is over 10 years old. How often should the battery be changed, I am thinking of running 3 batteries in series. Any further thoughts.

Sounds like you need RV electric 101: 12v side of life.

Replace them with 2 - 6 volt Golf Cart in series. Much better performance. 10 years is a long time for a battery to last even if you are anal about topping them up. 5-7 years is even good service. Time to change.

6V in series will give you 12 volts. 6V parallel gives you 6 volts.12V in series will give you 24V.

Thanks, thought I had that backwards, however, the wife is not going to allow me to put 2 6v batteries on to get only 12v :(

:h

Your TT is designed for 12V (lights, control boards for refrig, water heater & furnace, fans etc. I'm not sure what you mean by ONLY 12V
