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?


'63 Dodge 330

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.

If you are buying batteries from a farm store they likely also sell lead acid batteries that have epoxied plates and that will resolve the issue as well. Many tractor batteries have epoxied plates in them from the bouncing they endure from farm use. For instance all John Deere batteries are epoxied. Magna Power is another brand that uses all epoxy plates in batteries. Deka also makes many batteries that have epoxied cells. But yes what you are being told is true. Automotive batteries generally have "floating" cells in them and can touch and short out the battery.

I never heard of auto lead acid wet batteries not having physical separators between plates. and any contact would only be the result of a rather violent force, say tire shake?


Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
