These aren't your grandfathers basic batteries, though........... they'll handle a lot more than the battery that came in your 1995 Chevy truck ever would. That's one reason you see charging voltages upwards of 14.7 volts - enough to ruin standard batteries after a couple of years of that.My observations. The aux battery is undersized IMO. It is expected to augment ESS running accessories. It has low reserve capacity so it takes a beating. It’s a motorcycle battery. When you take a battery and cycle it hard, and fast charge it, it won’t last long. It’s small lol. This is why I think we’re seeing early failures. I think the best thing is to disable ESS and if your Jeep sits long periods, keep a battery tender on it so the aux battery isn’t expected to recover from a mostly discharged state. Treat your Jeep like a motorcycle
(standard batteries charge at 13.7-14.2 and more will not help them live a long life)
