BATTERY INSPECTION
M!XEl8N
BATTERY VISUAL INSPECTION (1)
The battery contains a visual test indicator which gives blue
signal when an adequate charge level exists, and white signal
when charging is required.
BATTERY VISUAL INSPECTION (2)
Make sure ignition switch is in Off position and all battery feed
accessories are Off.
1. Disconnect ground cable from battery before disconnecting
(+) cable.
2. Remove battery from vehicle.
Caution
Care should be taken in the event battery case is
cracked or leaking to protect hands from the electro-
lyte. A suitable pair of rubber gloves (not the house-
hold type) should be worn when removing battery by
hand.
3. Inspect battery carrier for damage caused by loss of acid
from battery. If acid damage is present, it will be necessary
to clean area with a solution of clean warm water and
baking soda. Scrub area with a stiff bristle brush and wipe
off with a cloth moistened with ammonia or baking soda in
water.
4. Clean top of battery with same solutions as described in
Step (3).
5. Inspect battery case and cover for cracks. If cracks are
present, battery must be replaced.
6. Clean the battery post with a suitable battery post cleaning
tool.
7. Clean the inside surfaces of the terminal clamps with a
suitable battery terminal cleaning tool. Replace damaged or
frayed cables and broken terminals clamps.
8. Install the battery in vehicle.
9. Connect (+) and (-) cables to battery in the order of
mention.
IO. Tighten the clamp nut securely.

Note
The temperature is an ambient temperature of the battery

BA-ITERY CHARGING
MYEICL
Caution
When batteries are being charged, an explosive
gas forms beneath the cover of each cell. Do not
smoke near batteries on charge or which have
recently been charged.
Do not break live circuits at the terminals of the
batteries on charge. A spark will occur where the
live circuit is broken.
Keep all open flames away from the battery.
Battery electrolyte temperature may temporarily be
allowed to rise to 55OC (131 OF). Increase of
electrolyte temperature above 55OC (131 “F) is
harmful to the battery, causing deformation of battery
cell, decrease in life of battery, etc.
CHARGE RATE
If the test indicator is white, the battery should be
charged as outlined below.
OPEN CIRCUIT VOLTAGE TEST (3)
1. Turn headlights on for 15 seconds.
2. Turn headlights off for 2 minutes to allow battery
voltage to stabilize.
3. Disconnect cables.
4. Read open circuit voltage.
5. If the open circuit voltage is under 12.4 volts,
charge the battery. (See BATTERY CHARGING)
LOAD TEST (4)
1. Connect a load tester to the battery.
2. Load the battery at 15 amps for 15 seconds to
remove surface charge.
3. Load the battery at the recommended discharge
rate. (See LOAD TEST RATE CHART)
4. Read voltage after 15 seconds and then remove
the load.
5. If the voltage is not maintained at the minimum
voltage in the LOAD TEST CHART throughout the
test, the battery should be replaced.
TSB Revision
When the dot appears or when maximum charge
shown below is reached, charging should be
stopped.
NOTE
When the charging is performed at 5 amps,
charging is virtually loo:! three hours after the
indicator’s indication changes from white to blue.
Use fast charging only in an emergency.
If the indicator does not turn to blue even after the
battery is charged, the battery should be replaced;
do not overcharge.
