Duracell 4 amp battery charger and maintainer instructions

Recharging a battery with a typical charge amp of around 4-8 amperes will take about 10-24 hours to charge fully. However, if you just want to boost your battery enough to start the engine, it would take about 2-4 hours—or, if possible, you can use another vehicle to jumpstart your battery.

Prolong your battery's life with proper charging and maintenance. The Duracell 4 Amp Charger/Maintainer can take depleted batteries from dead-to-start in just 2 hours.
