Check Battery Charge - Exmark STARIS E Series Operator's Manual

Check Battery Charge

Service Interval: As required
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 When the
ignition is set to the accessory mode, the module will
display the battery voltage. 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. Exmark 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.
Recommended Jump
Starting Procedure
Service Interval: As required
1. 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.
