Batteries not holding charge ???
I have 2 year old deep cycle Interstate batteries, usually they hold a charge for about 2 months but recently its much shorter than before. Is there a way to check the RV charging system? When I plug ...

If you let them go two months at a time without charging, it's close to miraculous they last two years. Conventional flooded cell lead-acid batteries can lose about 15% of their charge in a month at 80F. leaving battery in a discharged state cause sulfation to become irreversible.
