Methods of Che
cking Battery Condition
4.5. BATTERY SERVICE
4.5.1. NEW BATTERY PREPARATION
1. Remove battery from carton.
2. Place battery in a well ventilated area on a level non-
concrete surface.
3. Remove battery cell caps. Fill cells as required with
electrolyte (purchased separately) to proper level. Fill to
3/16” above cell plates. Filling battery with electrolyte
will bring the battery to 80% charged state.
4. With cell c aps removed, connec t battery charger to
battery terminals; RED to positive (+) and BLACK to
negative (-) terminal.
IMPORTANT: 3/16” above cell plates is the recommended
level. However do not try to measure this dimension. Never
place anything in battery other than specified electrolyte.
5. Slow charge the battery at 1 amp for 2 hours to
bring the battery to full charge.
6. After charging, check level of electr olyte and add as
needed to bring level to 3/16” above cell plates.
7. Reinstall cell caps.
8. Install battery into power unit.
9. Connect positive (+) cable (red) first, from wiring
harness to the positive terminal (+) on battery using
bolt and nut provided in hardware bag. Connect
negative (-) cable (black) last, to negative terminal (-)
on battery using bolt and nut. Apply a small amount of
grease over terminals to prevent corrosion.
WARNING
DO NOT over fill battery with electrolyte. Shield the
positive terminal with terminal cover locat ed on battery
harness. This prevents metal from touching the
positive terminal, which could cause sparks. The
electrolyte (acid) produces a highly explosive gas. Keep
all sparks, flame and fire away from area when charging
battery or when handling electrolyte or battery.
Electrolyte (acid) is a highly corrosive liqui d. Wear eye
protection. Wash affected areas immediately after
having eye or skin contact with electrolyte (acid).
Battery acid is corrosive. Rinse empty acid containers
with water and mutilate before discarding. If acid is
spilled on battery, bench, or clothing, etc., Flush with
clear water and neutralize with baking soda. Never
attempt to charge battery while installed on the walk
behind. Never use “BOOST” chargers on the battery .
4.5.4. BATTERY TESTING
4.5.2. BATTERY SERVICE
1. Remove battery.
2. Place battery in a well ventilated area on a level
surface.
3. Using distilled water, refill cells as r equired to cover
cell plates of which can also be visualized through the
plastic battery case.
4. W ith cell caps rem oved, connect battery charger to
battery terminals. Red to positive (+) terminal and
black to negative (-) terminal.
5. Slow charge battery at 1 amp for 10 hours.
6. If battery will not accept charge or is partially
charged after 10 hours of charging at 1 amp, replace
with new battery.
4.5.3. BATTERY STORAGE
If W alk Behind is to be stor ed out of s eason on its rear
bumper, it is recommended the battery be removed,
charged and stored.
1. Remove battery.
2. Perform battery serv ice.
3. Bring battery to full charge, if required.
4. Store battery in an area away from the Walk Behind
on a wood surface. DO NOT STORE BATT ERY ON A
CONCRETE SURFACE.
4.5.4. BATTERY TESTING
There are two types of battery tests: Unloaded and
Loaded. The unloaded test is the procedure that will be
discussed. It’s the sim plest and most comm only used.
An unloaded test is made on a battery without
discharging current. To perform unloaded testing,
check charge condition using either a hydrometer or
voltmeter.
1. Using a voltmeter, voltage readings appear instantly
to show the state of charge. Remember to hook the
positive lead to the battery’s positive terminal, and the
negative lead to the negative terminal.
2. A hydrometer m easures the spec ific gravity of each
cell. The specific gravity tells the degree of charge;
generally, a specific gravity of about 1.265 to 1.280
indicates full charge. A reading of 1.230 to 1.260
indicates the battery should be charged. The char t on
the next page shows the charge level as m easured by
syringe float hydrometer, digital voltmeter and five ball
hydrometer.
State of Charge Syringe Hydrometer Digital Voltmeter Five Ball Hydrometer
100% Charged w/ Sulfate Stop 1.280 12.80v Five Balls Floating
100% Charged 1.265 12.60v Four Balls Floating
75% Charged 1.210 12.40v Three Balls Floating
50% Charged 1.160 12.10v Two Balls Floating
25% Charged 1.120 11.90v One Ball Floating
