Original battery lasted 5 tears and replaced it 2007 with Gold. Lasted 5 years and again replaced 2012 with Gold. The last GOLD batter only lasted 3 years using a the same trickle charger designed to keep batteries fresh.
Had the last one for 5 years and it was great, worth the money.
I use my tractor 1 to 2 times a week all year long.
Good old die hard came through again! Price a little steep but you get what you pay for!
