Great deal on Titan riding mower/tractor batteries at Home Depot! I have a 22hp John Deere riding mower. Battery went dead after three years. I hadn't used it for several weeks, and battery was dead when I did. Jumped it a couple times and charged it, thinking it was just low on power. But the charge didn't hold. Take your old battery with you. Otherwise there's a $12.00 core deposit, refunded when you return old battery.
