My experience says 5-6 years, but I'm just now changing my mom's battery, and it's over 8 years old.
Anyone have a battery last longer than that?
Just curious...
i bought a battery for my 85 TA when i first bought it, i then swapped that battery into my gn right when i bought that, the battery lasted about 5-6 years total, it was a sears diehard.
