The only thing they do is to resist vibration better than normal batteries do and why they are used for off-road and rough service. The warranties on them are not as high as the normal ones can go and they do not last as long real world either, I used to sell them. Optima were the worst and way before they went to another country. The O'Reilly brand ones (Johnson Controls) are not even true gel batteries and cannot be mounted in any position like true AGM can, they still use liquid electrolyte rather than the gel type AGM uses and why the latter resist vibration better. 3 years for AGM is about right while top shelf Motorcraft liquid acid will go way longer (5-6 year on 7 warranty) although nobody goes as long as the long warranty says, well, maybe a few.
I found that you got better value with lesser warranty as they come closer to fulfilling the total period than the longer ones which more commonly do not. I currently run 2 year warranty ones and on 3 years two cars now and what they typically do. With 2 years I make money on the batteries (close to $70 each) and extra changes take 5 minutes each. Part of that savings is due to generalization of the battery instead of using the exact size and configuration of the OEM one most would use there. If you learn to read the cars and check batt volts every so often then you can pretty much tell when the battery is close to expiring, I have on the last several I've changed and not stranded once. When the battery drops to 12.2 volts at surface charge dissipated it's time to get a new one.
The AGM battery people that came into the stores to instruct us how to sell didn't care a whole lot about me grilling them about why they wanted us to tell (lie to,actually) the public about how much longer AGM batteries lasted with the warranties being as short as they were. When I pointed out that commonly the AGMs did not last as long as upper end conventional ones did they tried to shut me up by changing the subject. Another fun day in auto parts, I was continually stepping on toes left and right there.
Yours and do as you will with it...............
Pretty sad, what was the manufacturer's date on that battery if you don't mind me asking?KoiMaxx wrote: ↑Sun Feb 16, 2020 12:08 pmMine just crapped out today, wouldn't even crank more than 60rpm. Thing is only around 26 months, and I don't have any custom electronics installed. It sometimes gets below -4 here, but thankfully car is in a garage. Just really miffed about it since there was an event I really wanted to go to but had to cancel. Thanks Nissan!
How often do you drive this car? My wife and daughter each drive a Chevy Cruze. My daughter's is 8 years old with the original battery. Every time I test it, CCAs exceed sticker specs. Same battery in my wife's 1 year newer car showed a big drop in CCAs at 5 years. I had to replace it. But that car sits for days at a time, especially in the winter. I now try and run it more often with the new battery. When I tested the CCAs on my 2018 Rogue, CCAs were less than sticker specs since new. Same on two other Rogues I tested. Not happy that it is under spec, but it has not dropped any lower in the past year.KoiMaxx wrote: ↑Sun Feb 16, 2020 12:08 pmMine just crapped out today, wouldn't even crank more than 60rpm.

Funny you ask, it doesn't seem to have one unless it's pretty small and located exactly under the battery bracket. It's the original battery so I'd assume sometime in 2016-17?
It's my daily driver. I drive around 20miles in the city on weekdays and sometimes go out on weekends so i would think it's running long enough for the battery to charge. I connected my smart charger to it and it automatically went to reconditioning mode. It takes around 4-5 hours for one cycle, and the battery was around 12.16V when i checked with a multimeter after around an hour.tedc wrote: ↑Sun Feb 16, 2020 2:04 pmHow often do you drive this car?

Yeah, I'm seriously thinking of demanding a replacement since it should still be under warranty. It would net me at least another two years before I'd need to pony up for a new battery.
