I've had no problems at all with the 12v battery in my 2015 FFH, which is now 3 1/2 years and 50K miles old. Are there warning signs before the 12v battery dies and the car won't start? How long do these 12v batteries usually last? Or is there any "usually"?

Coming up on 5 years on my 2013. 65K miles. I assume the first indication I will get will be when I desperately need to go somewhere and the car will be dead. I am thinking about replacing anyways as 5 years appears to be a pretty good like on an OEM battery.

My battery took a dump at 5 years also. Does anyone know of an AGM type battery to replace the OEM one?

I believe Murphy installed an AGM in his FFE but he had to cut/modify the battery tray to fit it in. I have searched and have not found an AGM that fits the FFH.

If your car is driven daily, I don't think there is any big warning of a battery needing replacement. These cars don't need much to "turn on", so starting them isn't a problem. I think the biggest thing people notice is 1 of the following:
1. weird electrical issues. ie power window or door lock issues.
2. car goes in to battery saver mode on shutdown
3. battery just never seems to charge fully even after driving for an extended period.
