These types of batteries areclassified as non spillable wet electric storagebatteries and may be shipped as such. (Figure 13)Overcharging and undercharging can both decreasebattery life. Undercharging is more detrimental to abattery and decreases battery life more quickly thanovercharging. When using the charger supplied withthe battery, charge for 12 16 hours after everymowing to maintain optimum battery Constant Volt Charger is recommended forHawker a general rule of thumb, charge the battery to105 110% of the capacity used on the discharge. Toguarantee a complete and adequate recharge, ampere hours (Ah) should be returned tothe battery for every 1 Ah that is is the major cause of battery deterioration.

2 Forevery 13 180 F increase above 770 F ambienttemperature, the expected life of the battery goesdown by 50%. As the temperature rises,electrochemical activity within the battery increasesand the life is sealed lead batteries are batteries of this type must be recycled inaccordance with local recycling the battery s Open Circuit Voltage drops Volts or below, it should be charged. If theOpen Circuit Voltage is allowed to drop to and V, permanent damage may occur tothe battery. If the voltage drops below V, then thebattery may not be able to be types of batteries use a gas recombinationprinciple. During the charging cycle, Oxygen andHydrogen are formed.

But, some Hydrogen willescape, especially in an overcharge situation.

If battery has just beencharged, voltage may be artificially inflated andshould be allowed to rest for at least 4 hours inorder for voltage to Check open circuit voltage (OVC) at theconnector. A fully charged battery should havea minimum OVC of volts. If reading fallsbelow this number, charge overnight with aknown reliable charger. (See NOTE below)3. Repeat Step #1 above, then re check OVC. Ifvoltage has not recovered at all from originalreading, replace battery. If voltage has increased,try to start the mower. An older battery may notreach volts, but still may start the mowerwith no Whether the battery is placed back into service orreplaced, advise the end user that the batteryshould always be charged after use.

5 Although itmay still start the mower, the energy used to startit needs to be replenished to keep the battery ata high state of ON Known reliable Charger : This refersto any charger that has a minimum ampsavailable and charges at a constant voltage ofbetween and volts. If the charger s outputis less than volts, it will not fully recharge thebattery. For constant volt chargers, there is nocurrent limit. A 6 amp or 10 amp charger or evenmore is acceptable to use, but a minimum of 1 ampis required if the battery is discharged quite a 14: BATTERY REMOVAL & INSTALLATIOND isconnectWiringHarnessPush QuickRelease &RemoveFIGURE 15: BATTERY CHARGINGTo WallOutletTo BatteryLeadFOR MORE INFORMATION ON BATTERIES,CONTACT:HAWKER ENERGY PRODUCTS North Ridgeview DriveWarrensburg, MO 64093 9301, USAT elephone:(660) 429 2165 Fax:(660) 429 6397 LAWN & GARDEN PRODUCTELECTRICALS 1612109 TRACTOR BATTERY INFORMATIONGENERAL INFORMATIONWARNING: Batteries produce explosivegases.

KEEP VENT CAPS TIGHT AND NOT OPEN FLUSH COVER the Batteries Charging StateThere are two (2) types of wet cell batteries. (1)Maintenance Free and (2) Serviceable Batterieswhich have removable vent caps.(1) Maintenance Free Batteries are only free fromservicing in that you do not need to add water. Yet,the amount of acid or electrolyte may deplete due toexcessive heat or improper regulator settings.

7 Use aVoltmeter to check the Charging Status of thebattery. Re charge if necessary. Never open thesetypes of batteries.(2) Serviceable Batteries require maintenanceservice each year. To check to see if this type ofbattery is good, measure the Open Circuit Voltagewith a Voltmeter or take a Specific Gravity reading ofthe Electrolyte with a Hydrometer. If the circuitreading is below volts or the Specific Gravityreading is below SG, charge the battery. If theelectrolyte levels are too low for a Hydrometerreading add water to the : If water is added to a battery, make sureyou run the engine to charge the battery so theacid and water will mix. This is especiallyimportant in cold weather as the water in thebattery can the battery cells with clear, odorless drinkingwater. Distilled water is preferred, especially if thewater in your area has a high iron content. Fill eachcell until the level is to the bottom of the vent well in(Figure 17).

10 One reason is the battery does not have sufficient charge (refer to pages 54 55 for charginginformation). Another reason is a problem with the wiring Harness/Operator Presence SYSTEM (refer to pages56 64 for troubleshooting INFORMATION ). Finally, the last possible reason is a bad solenoid. The test procedurebelow will determine if the solenoid is good or the solenoid, disconnect the cable lead thatruns from the solenoid to the a mutli meter, check the battery forsufficient charge. It should read between open circuit voltage. If the reading isless than , then charge the battery beforeproceeding. For the solenoid to work properly,it needs a minimum of during the battery has sufficient charge, then checkthe solenoid s coil resistance. To check theresistance, disconnect the lead that goes to theprimary terminal. Check the resistancebetween the primary terminal and the base ofthe solenoid. If there is no resistance betweenthose two points, then the coil of the solenoid iseither burnt or one or both coil leads are this point, the solenoid should be there is resistance between the coils, then seeif the solenoid will click.
