Proper care can lengthen 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 can not 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 with a low battery.
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 much as 48 hours.
· At 2 amps the battery may need to be charged for as much as 24 hours.
· At 6-8 amps the battery will be charged in 2 to 3 hours.
Caution: At 6-8 amps a battery can overcharge.
Note: Using the recoil starter (ATM10E Briggs & Stratton model only) and then running the engine
will not recharge a dead battery.
