12 year life. That is a long auto AGM battery life. How were you able to extend the usable life that long ?Fullriver full throttle are also good batteries, they look exactly like the odesseys. 12 years ago I bought a 27ah fullriver for 40 dollars (old stock) and it still installed in my van as a start battery. They make fullsize batteries also.
I used a pair of Lifelien batteries in a Offroad pop-up camper for a few years. They are very heavy !They worked well. Sold the camper with the batteries and all electrical equipment. I have not heard back from the buyer. They must have worked out for him.Lifeline makes some good AGMs with above average specs as well..
