My battery failed me on Chrismass day in 1996. I was 250 miles from home in a small village, north of Quebec City.
The only battery available locally was from a remote service station, was not of the exact size but fitted in the tray.
It was a NAPA battery.
It is still in the car and had not caused me any problem in almost 6 years.
Why pay for a high price MB battery???
