$59 for a tractor battery, $199 for an optima. Guess that is why I have a tractor battery. I think it's 6 years old now, still going strong. If I get another 4 years out of it I'll not be surprised. 99% of battery performance and life is in how you treat it. Never let it go dead, don't overcharge it, keep the water level up, run a trickle charger on it periodically. I have a voltage regulator on my generator so that makes a big difference in life too. Abuse an optima and you'll ruin it too. I have nothing against optimas, they are a premium battery. I really don't own much that's premium I guess.
