How many years, or days of off grid camping do folks get out of a battery?
I think you're asking about life of the battery. Renogy reviews seem ok, but I don't have first hand experience. Some on this forum report many years of use out of various lead-acid battery types (of which AGM's are one).
In general, all batteries have a recharge cycle-life that can be from hundreds to thousands of times. While any particular brand or even a particular sample from that brand will vary, the depth-of-discharge is the main factor in overall battery life.
The deeper you take it down, the more harm. You want to stay at 50% discharge or less to avoid significant damage that will lessen the cycle-life. Also, charge the battery back up as quickly as you can. Best not to let it sit at a significant discharge level for very long. They like to be stored "topped up".
