SERVICE Charging the Battery Test and, if necessary, recharge the battery after the mower has been stored for a period of time. A voltmeter or load tester reading of 12.4 volts (DC) or lower across the battery terminals indicates that the battery needs to be charged.

Recommended charge rate is 4A/14.7V. • If your battery charger is automatic, charge the battery until the charger indicates that charging is complete. If the charger is not automatic, charge for no fewer than eight (8) hours. MODELS WITH AGM BATTERY • An AGM battery charger should be used. Recommended charge rate is 1.1A/14.8V. IMPORTANT! Do NOT use an automotive charger. • If your battery charger is automatic, charge the battery until the charger indicates that charging is complete. If the charger is not automatic, charge for no fewer than eight (8) hours. Jump Starting WARNING Failure to use this starting procedure can cause sparking, and the gases in the battery to explode. 1. Connect one end of the red cable to the disabled mower battery's positive terminal; then connect the other end of that cable to the booster battery's positive terminal. 2. Connect one end of the black cable to the booster battery's negative terminal; then connect the other end of that cable to the frame of the disabled mower, as far from the battery as possible. 3. Start the disabled mower following the normal starting instructions previously provided; then disconnect the jumper cables in the exact reverse order of their connection. 4.
