How to extend the life of my old 6v batteries

I have a set of 4 T-105 Trojan batteries that, so far, seem to be holding up. I originally installed them when we were boondocking more but for the last 4 years they have been stressed very little. I keep the water checked regularly and my multistage charger is constantly working, as I keep the trailer in storage with AC available.

Just wondering if there is anything else that will help extend their life. When I bought them they were around $70 each but now they appear to cost more than twice that amount, so I need to care for these as well as possible.

  • My original set of Trojan batteries lasted for more than 13 years. When my RV was 13 years old, I gave that set to another person, who kept using them, I have no idea how long.

    Keeping them topped off with water is critical. So is keeping them full, and recharging them soon after they have been discharged.

    Some say that EDTA is good for batteries, I found a advertiser at HomePower.com Magazine, and they sell enough for a set of golf cart batteries for about $13.
