Project Farm has tested car batteries along with the chargers, testers and restoration products that keep them alive. Every one of those matchups is indexed here, ranked as the test found it, with links to our write-up and the source video.
The tests measure cranking amps and reserve capacity for batteries, charge speed and recovery for chargers, accuracy for testers, and whether restoration products actually revive a tired battery. Products below are listed in the order they finished.
