Battery — Removal, Installation and Maintenance (Opel Frontera A)

The installed 12 V battery with a capacity of either Ah or, optionally, Ah consists of six cans containing positive and negative plates, which are immersed in a solution of sulfuric acid. The battery's job is to generate current to start the car, for ignition, for lighting, and for other electrical consumers.

Battery Care

The following maintenance should be performed from time to time to ensure that the battery lasts longer and maintains its maximum capacity.

1. Always keep the battery and surrounding parts clean. The surface of the battery must always be dry, otherwise surface leakage currents may occur between individual cells, causing the battery to discharge itself.

2. In cold weather, do not leave the battery uncharged, otherwise it will freeze. Weakly charged batteries freeze before charged ones.

3. The battery does not require maintenance, i.e. adding electrolyte and measuring its density is not required. There is a pointer on the top of the battery. The color change of the indicator gives an idea of the battery level. If the indicator shows green, the battery is charged and the car can be driven. As the battery discharges, the color of the indicator darkens and gradually turns black, indicating the need for charging.

If the indicator color disappears completely or turns yellow, this indicates a decrease in the electrolyte level as a result of its evaporation or prolonged use. This type of battery cannot be used. The battery needs to be replaced.



When installing another battery that requires service, the following is necessary to maintain it in good working order:

1. Clean the outer surfaces of the battery and wipe them dry, as this protects it from leakage currents between individual sections. Leakage currents lead to self-discharge of the battery (it is also recommended to carry out this procedure for maintenance-free batteries).



2. The electrolyte level should be between the marks on the outside of the battery case (illustration). The battery should be topped up with distilled water only.

Do not leave the battery in a discharged state, as it may freeze. A discharged battery freezes faster than a charged one (this also applies to maintenance-free batteries).

Removal and installation the battery

1. The battery is located in the engine compartment and is mounted on the console as shown in the illustration.

Disconnect the ground cable (1) from the battery. A wrench is used for this.

2. Disconnect the positive cable from the battery.

3. Loosen the nuts of the long bolts securing the bar and remove the bar.

4. Remove the battery from the engine compartment. Handle the battery with care.

The battery is installed in the reverse order of removal. First the positive cable is connected, then the negative cable.

When installing the battery, first clean the contacts and then lubricate them with special grease.
