 NOTE: If battery posts, cable
ends, or the battery case has a
build-up of white/green powder
residue, apply water and baking
soda to neutralize acid; then flush
off with warm soapy water.
3. Using a wire brush, clean the bat-
tery posts and cable ends removing
all corrosive buildup. Replace
damaged cables or cable ends.
CAUTION
Do not remove seal strip.
! WARNING
Battery acid is harmful if it contacts
eyes, skin, or clothing. Care must be
taken whenever handling a battery.
4. Using a multimeter, test the battery
voltage. The meter must read at
least 12.5 DC Volts for a fully
charged battery.
 NOTE: At this point, if the meter
reads as specified, the battery may
be returned to service (see step 8).
5. If the meter reads less than speci-
fied voltage, charge the battery
using the following guidelines.
A. When using an automatic bat-
tery charger, always follow the
charger manufacturer's instruc-
tions.
B. When using a constant-current
battery charger, use the follow-
ing Battery Charging Chart.
CAUTION
Never exceed the standard charging
rate.
! WARNING
An overheated battery could explode
causing severe injury or death.
Always monitor charging times and
charge rates carefully. Stop charging
if the battery becomes very warm to
the touch. Allow it to cool before
resuming charging.
Battery Charging Chart
(Constant-Current Charger)
Battery Charge
Voltage (DC) State
12.5 or more 100%
12.2-12.4 75%-99%
12.0-12.2 50%-74%
11.0-11.9 25%-49%
11.5 or less 0-24%
 NOTE: If the battery voltage is
11.5 DC Volts or less, some char-
gers may "cut off" and fail to
charge. If this occurs, connect a
fully charged booster battery in
parallel (positive to positive and
negative to negative) for a short
period of time with the charger
connected. After 10-15 minutes,
disconnect the booster battery
leaving the charger connected and
the charger should continue to
charge. If the charger "cuts off,"
replace the battery.
6. After charging the battery for the
specified time, remove the battery
charger and allow the battery to sit
for 1-2 hours.
7. Connect the multimeter and test
the battery voltage. The meter
should read at least 12.5 DC Volts.
If the voltage is as specified, the
battery is ready for service.
 NOTE: If voltage in step 7 is
below specifications, charge the
battery an additional 1-5 hours;
then retest.
