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...

It really depends on how you maintain them. My two Sam's Club 6v GC batteries are 10 years old and I dry camp 95 percent of the time. I usually don't stay more than 3-4 days in anyone spot and have minimal 12v requirements so they may be at 70 or 80 percent SOC. Once maybe twice a year I stay for a week and they are at 50 percent SOC. I always charge to full within a week. Also equalize and desulfate several time a year. My Walmart starting battery was just replaced and was 10 years old also, I charged it along with my house batteries but it was a sealed battery so I could not equalize it. My first set were Trojan 105's which only lasted 4 years because I did not know at the time how to maintain them. I never got more than about 4 years out of my cars because the just get charged by the alternator. If you fulltime your 12v requirements will be much higher.
