VMAX SLR85 12 Volt 85Ah AGM Deep Cycle Group 24 Battery 1.15kWh

We bought this battery for our travel trailer and used it for a year and 7 months before it died to the point where it cannot be reconditioned with the battery charger. I would have expected a full 2 years and maybe 3 years with fingers crossed. But I understand since we used it for boondocking with a solar panel and spent i.e. recently November through March on BLM longterm visitor area so it had done several daily cycles in hot temps. Would I buy the battery again, no. Do I regret my purchase, no.

I ordered one of these about a year and a half ago. It worked wonderfully up until the elements caught up to it and it nearly exploded. I would say it's not weatherproof and my prior deep cycles that were about half the cost lasted about 4 years each.
