22 DR ALL-TERRAIN FIELD and BRUSH MOWER Safety & Operating Instructions
Proper care can extend the life of a battery. Follow these recommendations to ensure your
battery’s best performance and long life:
■ Do not allow the battery charge to get too low. If the machine is not used, the battery
should be charged every 4 – 6 weeks.
■ Store an unused battery in a dry area that does not freeze.
■ Do not charge an already charged battery. In theory, our battery cannot be
overcharged with a trickle charger; however, when a battery is fully charged and the
charger is still on, it generates heat that could be harmful to the battery. A fully charged
battery will read 12V-13.2V with a voltmeter.
■ Do not continue to crank your engine when the battery charge is low.
Charging the Battery If the battery loses its charge, you'll need to use a trickle charger (like the DR® Battery
Charger) to recharge it. The charger should have an output of 12 volts at no more than 6-8
amps.
■ At 1 amp the battery may need to be charged for as long as 48 hours.
■ At 2 amps, the battery may need to be charged for as long as 24 hours.
■ At 6-8 amps the battery will be charged in 2 to 3 hours.
Note: Using the recoil starter and then running the engine will not recharge a dead or
significantly discharged battery.
WARNING! At 6-8 amps a battery can overcharge, overheat and
potentially leak acid. Do not leave the battery unattended while
charging.
