The battery in my '63 is mounted up front in the normal position. It's a "Super Start Premium" purchased at the local farm store.

This is the second brand new one I've had go bad and someone mentioned it could be how and where I have it mounted. His "theory" was that the lead plates could be coming loose because of the launch at the track.

I might also mention I grab this battery on occasion to use with the winch on my flatbed. I usually recharge it right away after using it either by running the car around or using a battery charger. Never let it sit discharged for any period of time.

Ideas on what's killing these?
