This wasn’t the outright best performer, but no other product here can beat this battery’s trade-off between output and price. The impressive spec of 45 AH and 450 cranking amps achieved five starts after 24 hours in the freezer, a strong performance in the part discharged cranking test, and just over four hours of keeping our test bulb illuminated.
