Hi Tim,
To prolong the life of the battery, you need to find a way to secure it because excessive vibration will cause the active materials on the pates to flake off more rapidly. You might try some non-skid floor treatment under the battery and retighten the hold down brackets. The battery should not get hot enough to cause a problem with the form unless there is a dead short or a charging system malfuction.
Kindest regards,
