Pump Sentry and Duralast Batteries

Hi everyone. We have a high water table and our pumps run pretty much all year round on a consistent basis. We splurged a few years ago and installed one of those triple systems and it has been pretty good, however we've never really lost significant power to rely on it much. Wanting to go over kill, I purchased the Pump Sentry (the largest version), to back up the main pump. After a couple years my first battery (Duracell) was blinking the replace battery buttoned on the Sentry. So, time to replace the battery (Even though I still think it should have lasted longer than 3 years)

I went ahead and purchased two, group 27 duralast deep cycle/marine batteries from AutoZone. Anybody use these before? Or does anybody have any better recommendations? I would have preferred AGM batteries, but we were facing a monster storm and I really wanted to make sure the batteries were set. I linked the two together around 8pm and they were fully charged by 6am.

Anyhow, looking for feedback on this battery or if I should just return them and get something different. They were only about $100 per battery. They are listed at 85 amp hours, however I see some but not much out there that says they are rated around 100. At 85 amp hours, the two would continue to power the main pump for around two full days, which I believe is more than enough time.

I say keep the batteries. After all, you purchased them, installed them and essentially are using them. It would be unethical to return them at this point now that the storm has passed.
