Apologies if the intent of my questions was not clear. I was trying to determine a probable cause of your rapid battery drain issue.

 

Mine also lasted 4 years on my 2020 110 S 4 cylinder with 68K miles. It started to show more frequent "start the vehicle to charge the battery warning" events. I purchased the replacement at Wal-Mart.

I just successfully replaced it, once I watched the video by from Simon and removed the seat. The seat was very easy to remove with a female star socket size E12.

I tried (half-heartedly) to pull the battery out from beneath the seat, as many of you report is possible. Candidly, I do not know how you folks were successful in yanking the battery from beneath the seat. I could not figure out how to do it without risking punching a hole in the battery or the vehicle.

I have had no troubles with the new battery -- and I have not registered it electronically with the car nor taken it to my dealer (which is several hours away). I very seldomly forget to turn off the auto stop/start-feature, so I think I have probably not run a lot of deep charge/discharge cycles through the AGM maintenance system (or so I suspect and hope)?

Enjoy !!
