Back in January 2003, I fitted a brand new Century NS40 ZLMF battery to my 1969 MGB which has been going perfectly ever since. I never once touched or looked at it over the last eleven years, but I decided it was time to change it just in case.
I checked with Century about the best battery for an old vehicle and they said it needed a lead antimony alloy battery. When I checked on what battery I had installed in my B, I found it was a sealed alkaline unit which in theory is not suited to vehicles like mine. But the “wrong” battery has lasted 11 years in my B and is sealed for life, so I decided to install the “wrong” battery again.
I did a test on the old battery when I removed it and found it was still in perfect condition! The battery is in front of my desk at Megatyre and is available free of charge to any local school kid in need of a “new” battery for their car…..
So I guess my MGB is ok for batteries until 2025! That really is exceptional longevity.
