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.

2 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.

3 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 .

4 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. The Oxygen, up to a point, isrecombined to form water at the negative 13: battery FOR 20 & 22 Hydrogen gas generation is reduced by the use ofthe pure lead tin material. But, some Hydrogen willescape, especially in an overcharge situation. So,DO NOT CHARGE in a closed container. Our batterycover is not considered a sealed the terminals of the battery are short circuited, anextremely high instantaneous current will begenerated.

DO NOT SHORT CIRCUIT THEBATTERIES ACROSS THE NEGATIVE ANDPOSITIVE of different capacities, age, or make shouldnot be mixed within the same battery should be charged prior to storage andcharged again before being put back into use. Thebattery may be stored with the unit. These batteriesare rated to 400 F and at that temperature it willretain its charge much better than at & GARDEN PRODUCTELECTRICAL108S 161220 & 22 battery INFORMATION continuedREMOVAL/NORMAL RECHARGING1.

The charger will drain the TEST PROCEDURE (COURTESY OFHAWKER ENERGY PRODUCTS INC.)Procedure:1. disconnect battery from charger, wire harness,or any other circuit.

7 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 .

8 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. 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.

9 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.
