Lead acid batteries

I had the OE battery in my 2000 4WD Dakota last 6years, then just quit. The replacement Autozone premium battery lasted 6 years, then just quit. Have another AZ battery, see how it does. Still have the original front wheel bearings with 228K on it.

My wife has a 79 Firebird she bought new. The OE battery lasted 11 years.

I have a Cub Cadet I bought used in 93. Have had widely varying results on battery life, some only 2-3 years, some 7-8 years.
