5.7.4. 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
simplest and most commonly 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 measures the specific
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
before testing. The Battery Condition Chart
shows the charge level as measured by
syringe float hydrometer, digital voltmeter
and five ball hydrometer.

5.7.5. 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
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 caps removed, connect battery
charger to battery terminals; RED to positive
(+) and BLACK to negative (-) terminal.
IMPORTANT: 3/16" above cell plates is the recommended
level. DO NOT place anything in battery other than specified
electrolyte.
WARNING
DO NOT OVERFILL!

DO NOT attempt to service or charge the battery
while it is installed in the machine. DO NOT use
"BOOST" chargers on the battery.
5. Slow charge the battery at 1 amp for 2
hours to bring the battery to full charge.
6. After charging, check level of electrolyte
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.
10. Install battery retainer and positive
terminal cover.
Shield the positive terminal with terminal cover
located on battery harness. This prevents metal from
touching the positive terminal, which could cause
sparks. Cables must be connected to battery
terminals in the proper position. RED (Positive) cable
must go to the ( + ) terminal. BLACK (Negative) cable
must go to the ( - ) terminal.
