Battery Care (Electric-Start Models)
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, charge the battery every 4 – 6
weeks. Operate the engine for at least 45 minutes to maintain proper battery charge.
•
Store an unused battery in a dry area that does not freeze.
•
Do not charge an already charged battery. In theory, you cannot overcharge our battery 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
Operate the Trimmer engine for at least 45 minutes to maintain proper battery charge. If the battery loses
its charge, you will 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 2 amps.
•
At 1 amp, the battery may need charging for as long as 48 hours.
•
At 2 amps, the battery may need charging for as long as 24 hours.
NOTE: Using the recoil starter and then running the engine will not recharge a dead or significantly discharged
battery.
To connect a battery charger to your DR TRIMMER/MOWER, follow the steps listed below.
1. Detach the two battery wires going to the battery on your DR TRIMMER/ MOWER.
2. Attach the black (-) battery charger wire to the battery negative (-) terminal, and attach the red (+)
battery charger wire to the battery positive (+) terminal.
3. Plug the battery charger into an outlet.
WHEN YOU ARE FINISHED CHARGING THE BATTERY, DISCONNECT THE CHARGER FROM THE
OUTLET FIRST, THEN DISCONNECT THE BATTERY CHARGER WIRES FROM THE BATTERY. IF YOU
LEAVE THE BATTERY CHARGER WIRES CONNECTED TO THE BATTERY, THE BATTERY WILL DISCHARGE
ITSELF BACK INTO THE CHARGER.
