Sub Battery
- CHECK BATTERY (USE CONSULT)
Check the battery, using CONSULT. Refer to DIAGNOSIS PROCEDURE .
Is the check result normal?
YES
GO TO STEP 2.
NO
Replace battery. Refer to REMOVAL AND INSTALLATION .
- CHECK BATTERY (USE EXP-800 NI OR GR8-1200 NI)
Check the battery, using EXP-800 NI OR GR8-1200 NI.
Is the check result normal?
YES
INSPECTION END (The battery is normal.)
NO
Replace battery. Refer to REMOVAL AND INSTALLATION .
BATTERY DIAGNOSIS WITH EXP-800 NI OR GR8-1200 NI
To diagnose and confirm the condition of the battery, use the following special service tools:
- EXP-800 NI Battery and electrical diagnostic analyzer
- GR8-1200 NI Multitasking battery and electrical diagnostic station
Refer to the applicable instruction information for proper battery diagnosis procedures.
For gas leakage, remove the 12V battery from the vehicle to charge in a well-ventilated area.
BATTERY DIAGNOSIS WITH EXP-800 NI OR GR8-1200 NI
Check the Battery Indicator
Check the indicator placed at the top of battery to judge the battery state. If the battery state is "CHARGING NECESSARY" charge the battery according to "Charging The Battery".
If indicator is hard to check, remove battery from vehicle.
Charging The Battery
- For gas leakage, remove the battery from the vehicle to charge in a well-ventilated area.
- There are two charging methods: Quick charging and standard charging.
"Standard charging" is used for recovering the state of charge.
"Quick charging" restores the battery to the state capable of engine start and the READY state.
- Never "quick charge" a fully discharged battery.
- Keep the battery away from open flame while it is being charged.
- When connecting the charger, connect the leads first, then turn on the charger. Never turn on the charger first, as this may cause a spark.
- While charging the battery, maintain 12V battery temperature as follows:
Standard charging: 45 °C (113 °F) or less
Quick charging: 55 °C (131 °F) or less
- Maintain charging voltage at 15 V or less during battery charge.
| Approximate charge condition | Charge current (A) | Charge time (h) |
|---|---|---|
| Fully charged | 5 | 2 |
| 3/4 charged | 2.5 | |
| 1/2 charged | 5 | |
| 1/4 charged | 7.5 | |
| Almost discharged | 9 | |
| Completely discharged | 10 |
| Approximate charge condition | Charge current (A) | Charge time (h) |
|---|---|---|
| Fully charged | - | - |
| 3/4 charged | 13 | 0.5 |
| 1/2 charged | 26 | |
| 1/4 charged | ||
| Almost discharged | ||
| Completely discharged | - | - |
- The battery indicator shows "OK" at the completion of battery charging.
- The ammeter reading on your battery charger will automatically decrease as the battery charges. This indicates that the voltage of the battery is increasing normally as the state of charge improves. The charging amps indicated above refer to initial charge rate.
