Any specific time to replace Batteries?
I know you should replace tires between 5 to 7 yrs, definitely before the 10 yr mark. So does anyone change their rigs batteries by a certain time? Ours are about 5 or 6 yrs old now. We live full tim...

The deeper the discharge the shorter the life.
The longer between full 100% recharges the shorter the life.
Add solar charging and life span may improve dramatically.
good quick summary and excellent advice.
I'll add that most RV user's won't ever come close to being limited by the rated cycle life on a good 6V GC or real 12V deep discharge. Don't discharge GC below about 25 percent SOC, 12V below 50 percent.
True GC deep discharge are good for over 500 cycles to very deep discharge, 12V trojan deep discharge similar life but only to 50 percent. How many of us will ever discharge that many times to those levels?
But the key is to get them charged back up to a TRUE 100 percent full charge within a few days or week at the longest. watching water level, equalizing when needed.
Now if you have a marine battery, I believe cycle life is considerably less. they still have thinner plates for starting current and being a combo battery, likely lower cycle life.
