??? Wet cell Truck Batterys

Test Cells

Test Cell Groups

Test Cell Groups together

A battery load tester at a shop or store so equipped would be next for me.

The individual cells.
The battery.
Then the battery group.

All need verification.
Smallest to largest array.

Placed under load is the fastest way of finding out if “good” batteries really are just that.

The battery charger used to maintain them need also be of a quality and design to maximize lifespan. A PD-465 is a minimum.

Battery insulation and ventilation also a concern. Electric warming needs research. It’s not just for Arctic conditions.
