This hand-held tester identifies charging and starting problems on 6 or 12 volt systems. Full 75 amp load test. The voltage is also reduced to 13.2 volts which is below the 13.8 volt gassing point of a battery which can cook the water out and kill the battery.
Operation is fully automatic and it also has reverse polarity protection.
The decrease in charge time probably means little of nothing to the average individual, but to the shop owners it can be the difference between a happy or unhappy customer. For the collector, it is essential. For use with liquid filled batteries. Quick connect alligator clip connections. More than just a battery charger, the optimate precisely assesses, charges, maintains and even recovers deep-discharged batteries.
