My Panasonic was 3 years old last month from the delivery date, I forgot the dome light a few times while at the gym this winter, battery didn't mind, I'm curious to see how long it lasts with the 2017+ charging system. The Panasonic in my old RAV4 I replaced after 12 years, it was still starting the truck below -20C.

After draining it completely like 3-4 times this fall by forgetting the dome light overnight again and again, even after being put on a battery charger each time and not just driven, the stock panasonic finally gave up and couldn't muster the amps to crank over a -25C block of ice of an engine. Strange, my NOCO 3000A jump starter didn't struggle...
I've claimed in the past that AGM batteries weren't ideal for a 2017+ since they spike the charging voltage high intermittently and AGM has a lower charging voltage than flooded. Though in the the years since, the amount of cars using AGM batteries and start/stop systems has increased a lot and those cars constantly alternating between high charge and discharge rates and their almost universal use of AGM hint at me that I was probably making too much of it. So I went with a beefy Napa-branded East-Penn 9A35/85 with 600CCA/100RC/50Ah.
