|
Allowing batteries to stand for an extended period of time without recharging them will result in reduced performance and service life. To preserve optimum battery performance and life, recharge batteries in storage when the open circuit voltage drops to 12.4 volts.
Note: To prevent damage due to freezing, battery should be fully charged before putting away for winter storage.
Charge batteries in an open well ventilated area, away from spark and flames. Unplug charger before connecting or disconnecting from battery. Wear protective clothing and use insulated tools.
Danger
Charging or jump starting the battery may produce explosive gases. Battery gases can explode causing serious injury.
-
Keep sparks, flames, or cigarettes away from battery.
-
Ventilate when charging or using battery in an enclosed space.
-
Make sure venting path of battery is always open once battery is filled with acid.
-
Always shield eyes and face from battery.
Danger
Battery electrolyte contains sulfuric acid, which is poisonous and can cause severe burns. Swallowing electrolyte can be fatal or if it touches skin can cause severe burns.
-
Wear safety glasses to shield eyes, and rubber gloves to protect skin and clothing when handling electrolyte.
-
Do Not swallow electrolyte.
-
In the event of an accident, flush with water and call a doctor immediately.
Caution
If the ignition is in the “ON” position there is potential for sparks and engagement of components. Sparks could cause an explosion or moving parts could accidentally engage causing personal injury.
Be sure ignition switch is in the “OFF” position before charging the battery.
-
Check the voltage of the battery with a digital voltmeter or with the message display. If the voltage is less than 12.4 volts, the battery may need to be charged.
Important: In order to prevent damage to the battery, use an automatic 12 volt smart charger approved for use with AGM type batteries with an output of 3.5 amps or less. Toro recommends the use of battery charger P/N 135-7024. Make sure the negative battery cable is disconnected before charging and that the charger is set to the correct mode for 12V AGM batteries.
-
Connect the negative battery cable.
Note: If the positive cable is also disconnected, connect the positive (red) cable to the positive battery terminal first, then the negative (black) cable to the negative battery terminal. Slip insulator boot over the positive terminal.
Note: If time does not permit charging the battery, or if charging equipment is not available, connect the negative battery cables and run the vehicle continuously for 20 to 30 minutes to sufficiently charge the battery.
Recommended Jump Starting Procedure
-
Check the weak battery for terminal corrosion (white, green, or blue “snow”), it must be cleaned off prior to jump starting. Clean and tighten connections as necessary.
Caution
Corrosion or loose connections can cause unwanted electrical voltage spikes at anytime during the jump starting procedure.
Do Not attempt to jump start with loose or corroded battery terminals or damage to the engine may occur.
Danger
Jump starting a weak battery that is cracked, frozen, has low electrolyte level, or an open/shorted battery cell, can cause an explosion resulting in serious personal injury.
Do Not jump start a weak battery if these conditions exist.
-
Make sure the booster is a good and fully charged lead acid battery at 12.6 volts or greater. Use properly sized jumper cables (4 to 6 AWG) with short lengths to reduce voltage drop between systems. Make sure the cables are color coded or labeled for the correct polarity.
Caution
Connecting the jumper cables incorrectly (wrong polarity) can immediately damage the electrical system.
Be certain of battery terminal polarity and jumper cable polarity when hooking up batteries.
Note: The following instructions are adapted from the SAE J1494 Rev. Dec. 2001 – Battery Booster Cables – Surface Vehicle Recommended Practice (SAE – Society of Automotive Engineers).
