More Battery Problems

Thanks Folks your all right on. I didn't know until I took the batteries into my battery guy! First of all he told me the average battery life was 3-1/2 to 4-1/2 years. He looked at my two coach batteries and they were both 9-1/2 years old. Completely wore out, bad cell, and the top of one of the coach batteries the battery case was broken. I cleaned the battery case up with water and baking soda and dried everything. I then installed 2 new Deep Cycle RV batteries and had my son come over with his voltage meter and one new battery read 14.4 the other 14.5 I also had him check my chassis battery and it was 14.5. The only thing I didn't like was paying $250.00 out the door for both batteries. I will keep an eye on the batteries for awhile.
