Caution: Performing battery health and maintenance checks requires some special precautions. Remember that the hydrogen released by the electrolyte is a highly explosive gas. Do not smoke, and do not approach the work area with an open flame or a lit cigarette! Do not forget that the actual electrolyte is dilute sulfuric acid, which, if it gets into the eyes or on open areas of the body, can cause severe chemical burns. The electrolyte can also easily damage the fabric of clothing and the paintwork of body panels!
Caution: When disconnecting the battery, always disconnect the negative cable from the battery first - connect it last! Read the instructions and recommendations in chapter 5.
1. The vehicle-mounted 12-volt battery is placed under the hood in the left front of the engine compartment and consists of six cans that contain positive and negative plates (lamellas), immersed in a solution of sulfuric acid. The main task of the battery is to provide the current needed to start the engine, ignite/activate the glow plugs and for lighting, as well as to provide power to other on-board or auxiliary electrical consumers.
2. Modern batteries with minimal care requirements (see below) and under normal conditions do not require additional maintenance and are designed, on average, for 4 years.
3. When installing additional electrical and electronic equipment on the vehicle, the load on the battery may increase and a larger battery may be required - consult an Opel Dealership about the possibility of using such a battery.
Attention: The battery charging system is designed for strictly defined capacity values! Installing a battery with both too large and insufficient capacity will lead to premature failure of the battery - strictly follow the recommendations of specialists, if necessary, make the appropriate adjustments at Opel's service station.
4. If you do not plan to use the car for 30 or more days, disconnect the negative cable from the battery in order to prevent its premature discharge, and in winter, at very low outside temperatures, it is recommended to remove the battery and store it in a room with positive (but not high, up to +10°С) temperature.
Note: After connecting the battery, you must enter the security code of the infotainment system, reset the chronometer and set the date on the information display, and, if equipped, synchronize the power windows and sunroof (see chapter «Controls and methods of operation»).
5. Of particular importance for ensuring the reliability of starting the engine and long-term trouble-free operation of the battery is the quality of the contact of the battery terminals with the connecting wires. Every time you look under the hood of the car, check the reliability and completeness of their contact, fully tighten the fasteners.
6. A conscientious attitude to the implementation of routine preventive maintenance of the battery is the only guarantee of a quick and trouble-free engine start. Before you start servicing the battery, make sure you have all the necessary materials and tools at hand to guarantee the safety of work (see resist. illustration), try to use only non-sparking tools.
7. Before starting work, be sure to turn off the engine and turn off all consumers of electricity. Disconnect the negative cable from the battery. When performing battery maintenance, wear safety goggles and gloves and keep children away from the work area.
