June 2019, 12yr old Motorcraft battery becoming unreliable, even with maintainer hooked up. Finally had to replace with new battery (from Costco).
I would like to know who makes Motorcraft batteries ?!!!
The original battery in my 1998 E150 lasted 12+ years. No battery tender, but it was a daily driver. I did clean the outside once or twice a year. Even though it was considered "maintenance free", I pried the caps off and topped off each cell at the same time
(very little water required).
The second battery did not last as long. Probably because I left the interior lights on 3 or 4 time and it was no longer a true daily driver any more
(couple of times a week).
20 yo vehicle on 3rd battery ! :C
With COVID-19, it gets driven once every 2+ weeks. It starts, but I don't know about next winter.
