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?


G-Forces. Causes the plates to move and possibly come into contact with each other or come loose.

Conventional lead-acid batteries should be mounted crossways to the C/L of the car. So the plates are parallel to the direction of travel. AGMs
don't care

If the results don't match the theory, change the theory.
