Hard to believe but i bought one of these 15 years ago to be used in my big block 66 corvette. The car was driven monthly and briefly charged occasionally. The longest lasting battery we have ever had. I just replaced the battery recently only because it would not hold an extended charge but would still start the car with a jump.

Would Recommend

Should turn a hot 440 over
