What is the voltage of my riding mower battery?
WARNING! Before performing maintenance on any unit, always disconnect and ground the spark plug wire.
WARNING! Batteries give off an explosive gas while charging. Charge the battery in a well ventilated area and keep away from an open flame or pilot light as on a water heater, space heater, furnace, clothes dryer or other gas appliances.
Although these batteries vary in size and shape, all batteries on our riding mowers operate at a nominal 12-volts.
It is recommended to charge the battery before the first use as well as anytime the battery is not used or stored for more than a month. During down time, like before the unit was purchased or when in storage, a battery can become dormant. Although the riding mowers do have a self charging system, the battery will not rejuvenate electrolytes from the down time. This will cause a shortened life for the battery. Normally charge the battery between 2 to 6 amps per hour. Do not charge any battery at more than 6 amps per hour.
If you have a serviceable battery and you charge it at a lower amp rate, use a hydrometer to test the acid. The hydrometer should read a minimum of 1.260 before putting the battery back into service. Note: These batteries are sensitive to dormant time and cold temperatures.
Take special care to the battery for any down time that is expected to last for more than a month, or experience colder temperatures...
NOTE: Make sure to remove the battery from the unit and store in a warm dry location.
NOTE: Charge the battery before storing and before putting it back into service.
NOTE: Consider charging the battery during this storage period if it lasts longer than 2 months. If further assistance is needed, please click the 'service' link at the to of this page to find a local service dealer.
