Well. 3 years and 3 months and my Bosch AGM battery finally died. But note that it was actually built 3 years prior to purchase (ugh - didn't notice until after I installed).
Telltale signs over the last 2-3 weeks were slight hesitation upon starting and my dashcam voltage cutoff monitor (Blackvue Power Magic Pro) was cutting power to the dashcam right away (indicating < 12v).
Got 11.1 volts last night and then not surprisingly it finally didn't start this morning.
Got a free replacement (has a nice 4 year warranty) at Pep Boys. Though interestingly it no longer shows the Bosch AGM Group 24 battery as compatible.

^^^^When I sold my ISF back in July, it had a Bosch AGM battery that endured four hot Arizona summers. It was still going strong. My experience does not correlate with yours.
I don't like Costco batteries, I am a member, because they generally do not stock all sizes and will kludge the wrong size to make it fit.

I’ve had my RR racing battery on my DD ISF in SoCal desert temps of 125 degrees for 3 years now with not a single problem. Not only that but I never charge it and sometimes have the car sit for a week and no issues with the battery.

Battery is probably going to die soon, electrical meter reads 11V with ignition on - use to be 12V, looking to get it replaced, can anyone provide feedback on Exide Edge AGM?

And yes, I realize that the stereo is mostly powered by the alternator when the car is running. However, high powered stereos can draw from the battery intermittently at low RPM.

Bosch's website gives two S6 part numbers S6-78DT and S6521B, and ambiguously lists them at group 24 in the header page and group 34 in the details page.
Pep Boys' website cannot confirm ISF fitment for what they call the 24-710BAGM, but shows a crop of other group 24 batteries with similar dimensions and terminal orientation as fitting. Wondering about trying 34-770BAGM. More CCA's than 24-710BAGM but 1.0in shorter, 0.3in wider, about the same length.

Costco batteries are great... you may or may not have to take your own measurements to get the right battery, but the warranty is by far better than any other battery on the market. Let's just say I haven't "paid" for a battery in 12 years.
