How long does your Optima battery last?

TOP said
14 years on one and 7 on the second. Both pre Mexico . Still using both. Going to find a good US made replacement soon.

Both batteries still in cars the orange top must be 16 now and 9 on the red. Just started using battery tender this year. Think i should put a new battery in trunk for a spare. Bought a 6 volt for an old tractor i have lasted 2 years.
