Battery: Testing and Inspection
1. CHECK BATTERY ELECTROLYTE LEVEL
Check the electrolyte quantity of each cell.
Maintenance-Free Battery;
If under the lower level, replace the battery (or add distilled water if possible). Check the charging system.
Except Maintenance-Free Battery:
If under the lower level, add distilled water.
2. Except Maintenance-Free Battery:
CHECK BATTERY SPECIFIC GRAVITY
Check the specific gravity of each cell.
Standard specific gravity: 1.25-1.29 at 20 °C (68 °F)
If the specific gravity is less than specification, charge the battery.
3. Maintenance-Free Battery:
CHECK BATTERY VOLTAGE
Measure the battery voltage between the negative (-) and positive (+) terminals of the battery.
Standard voltage: 12.5 - 12.9 Volt at 20 °C (68 °F)
HINT:
- Before measuring the voltage, turn the ignition switch OFF and turn off the electrical systems (headlight, blower motor, rear defogger etc.) to remove the surface charge.
- If the vehicle has been running, wait 20 minutes or more after the vehicle stops before measuring the battery voltage.
If the voltage is less than specification, charge the battery.
HINT: Check the indicator as shown in the illustration.
4. CHECK BATTERY TERMINALS AND FUSES
a. Check that the battery terminals are not loose or corroded.
b. Check the fuses for continuity.
