Dry Battery Service
DANGER
Activating a battery can be dangerous.
The battery should be taken to a reliable
service station, battery store, or power
equipment dealer where a trained techni-
cian can activate the battery safely. DO
NOT attempt to activate the battery unless
you are experienced in battery service
work. The following activation and charg-
ing instructions are provided for use by a
trained battery technician.
DANGER
Battery electrolyte is a poisonous and cor-
rosive sulfuric acid solution.
●
Avoid spillage and contact with skin,
eyes, and clothing - causes severe
burns.
●
To prevent accidents, wear safety gog-
gles and rubber gloves when working
with electrolyte.
●
Neutralize acid spills with baking soda
and water solution.
To fill (activate) battery with electrolyte (if battery
has been shipped dry):
1. Remove the battery cover plate and battery
clamp, disconnect the battery cables and lift
the battery out of the tray.
IMPORTANT:
Battery must be removed from
the mower before filling with electrolyte.
IMPORTANT:
Obtain and use only battery
grade sulfuric acid electrolyte with a 1.265
spe cific gravity to activate the battery.
DO
NOT
use water or any other liquid during initial
activation.
2. Remove the filler caps and carefully fill each
cell until the electrolyte is just above the
plates.
3.
After the battery is filled with electrolyte, re-
place the filler caps and charge the battery.

Battery Charging
DANGER
BATTERIES PRODUCE EXPLOSIVE GASES
●
Charge the battery in a well-ventilated
area, so that gases produced while
charg ing can dissipate.
●
Keep sparks, flames, and smoking ma
-
terials away from the battery at all
times.
●
Make sure the battery cap vents are
open (check manifold vent on each
cap).
●
Make sure the battery charger is un-
plugged before connecting or discon-
necting cables to the battery.
IMPORTANT:
Always disconnect the negative (-)
battery terminal before charging. Failure to do so
can result in damage to the ECU.
1. Charge the battery at 15 amps for 10 minutes.
DO NOT
exceed 20 amps maximum recom-
mended charging rate. Charge until specific
gravity is at least 1.250. Total charging time
should not exceed one (1) hour.
2. After charging the battery, adjust the electro-
lyte level to the bottom of the vent wells [1/4 to
1/2 in. (6 to 13 mm) above the plates].
IMPORTANT: DO NOT
overfill the battery.
Electrolyte will overflow through the vented
caps onto parts of the machine and
WILL
result in severe corrosion.
3.
Install the battery.
