Subsection 04 (CHARGING SYSTEM)
WARNING
Battery electrolyte is caustic. To prevent
spillage, ensure battery cell caps are suffi-
ciently tight to properly seal each cell.
Battery Electrolyte Level
Check electrolyte level in each cell, add distilled
water up to the upper fill level line.
NOTICE
Add only distilled water in an acti-
vated battery.
Battery Testing
There are 3 types of battery tests.
TEST
METHOD
COMMENT
Voltage
test (load
applied)
A dynamic voltage test with a load
applied gives an accurate indication
of the condition of the battery.
This
is the most recommended method.
Voltage test
(no load)
A static voltage test is carried out
without discharging current. It is
the simplest and most commonly
used but the most likely to give false
results.
Battery
electrolyte
reading
Gives an accurate indication of the
charge condition of each cell.
Battery Voltage Test (Load Applied)
Use a load testing device such as the
ELECTRO
SPECIALTIES BATTERY LOAD TESTER (P/N 710)
. It
has a 500 A carbon pile adjustable load.
Follow battery load tester instructions.
Apply a load of 3 times the ampere-hour rating
of the battery for 14 seconds, then check battery
voltage.
BATTERY VOLTAGE TEST (LOAD APPLIED)
TIME TO MEASURE
INTO TEST
VOLTAGE
14 seconds 10.5 Vdc min.
If battery voltage has dropped below specifica-
tion, the battery storage capacity has decreased
appreciably and the battery should be replaced.
Battery Voltage Test (No Load)
NOTE: Be aware that the voltage test can indi-
cate that the battery is in good condition even
though the battery does not have enough stored
energy to crank the engine. A load test gives a
more accurate indication of the condition of the
battery.
If the battery has just received a charge, allow it to
rest for 1-2 hours before taking a voltage reading.
Set multimeter to Vdc and measure voltage at bat-
tery terminals.
FULLY CHARGED BATTERY VOLTAGE (NO LOAD)
12.6 Vdc minimum
Battery Electrolyte Reading
NOTE: Do not top up cell electrolyte level with
distilled water prior to taking an electrolyte read-
ing.
Check charge condition of each cell using a hy-
drometer.
NOTE: A hydrometer measures the charge of a
battery in terms of specific gravity of the elec-
trolyte.

1. Hydrometer
Most hydrometers give a true reading at 21°C
(70°F).
In order to obtain the correct value, adjust the ini-
tial reading by adding or substracting the number
indicated in the following table.
