Battery — removal and installation (Opel Omega B)

Removal

1. The battery is located on the left side of the engine compartment.

2. Disconnect the negative terminal wire.



3. Remove the fuse jumper cover if necessary and disconnect the positive battery terminal.

4. Loosen the bolt and remove the battery retaining clamp. Remove the battery from the vehicle.

Installation

Installation is carried out in the reverse order of removal. Lubricate the battery terminals with technical petroleum jelly before connecting the wires.

Regular battery and low maintenance battery

Examination

It is recommended to check the specific gravity of the electrolyte every three months to determine the battery charge.

	Air temperature above 25°C	Air temperature below 25°C
The battery is fully charged	1,210 – 1,230	1,270 – 1,290
The battery is charged to 70%	1,170 – 1,190	1,230 – 1,250
The battery is discharged	1,050 – 1,070	1,110 – 1,130

Check the specific gravity of the electrolyte in each section of the battery. If the specific gravity of the electrolyte between sections differs by more than 0.040, the battery must be replaced.

Maintenance free battery

Examination

The battery does not require topping up the electrolyte or checking its density. An indicator is used to check the battery condition.

Regular battery and low maintenance battery

Charger

When charging the battery, the electrolyte temperature should not exceed 37.8°C.

1. The charging current should be 3.5–4 Amperes. Charging should be continued until the specific gravity of the electrolyte increases over 4 hours.

2. You can also use a battery charger to continuously charge the battery with a charging current of 1.5 amps. This charger can be left on overnight.

Maintenance free battery

Charger

Charging this type of battery takes longer than charging conventional batteries. Charging should be done at a voltage of 13.9-14.9 volts, the charging current should not exceed 25 amperes.
