Drivers who work nights often start their cars in the coldest hours. Tighten the hold-down clamp so the battery cannot rock on bumpy roads. Electrical gremlins after a battery swap are often just a loose clamp.

Care tips for spiral-cell AGM batteries
The coiled plates are held under pressure, which makes the cell very rigid. Hot rods with relocated batteries often go spiral for the shape alone. Leave the vents of a spiral battery alone; there is nothing to service inside.
