Note. The information below should be considered as a guide only. When using the battery, follow the manufacturer's instructions.
1. When leaving the factory, all models are equipped with maintenance-free batteries. Under normal operating conditions, such batteries do not require any attention throughout their life.
2. If the condition of the battery is suspicious, remove the battery as described in paragraph 4 and check the electrolyte level in the jars, which is visible through the transparent battery case. The level should be the same in all cans, about 5 mm above the top edge of the plates. If necessary, the electrolyte level can be increased by adding distilled water to the jars (not acid!).
3. The state of the battery in the first approximation can be estimated by measuring the density of the electrolyte.
4. Measure the density of the electrolyte in each jar and compare the results with the values shown in the following table. Please note that the electrolyte density given below is for a temperature of +15°C. If during the measurement the temperature differs from the indicated temperature, then for every 10°C above 15°C add 0.007 to the measured value, and for every 10°C below 15°C subtract 0.007.
5. The density of the electrolyte in all banks should be approximately the same. If in some bank the density of the electrolyte differs from the others by 0.04 or more, then this means that there is an electrolyte leak, or a malfunction of the battery's working plates. In both cases, the battery is defective and needs to be replaced.
6. If the difference in electrolyte density across the banks is within acceptable limits, but the battery is discharged, it should simply be charged in accordance with the manufacturer's instructions
7. You can also check the condition of the battery with a voltmeter. Connect a voltmeter to the battery terminals. A fully charged battery must have a voltage of at least 12.5 V. This test will give a correct result if the battery has not been charged for the past six hours. If this is not the case, turn on the high beams for 30 seconds, then turn off the headlights and wait a few more minutes. After that, you can start checking. All electrical consumers on the vehicle must be turned off. Therefore, first check that all doors and the trunk lid are securely closed.
8. If the voltage at the battery terminals is between 12.2 and 12.4 V, then the battery is partially discharged. Voltage below 12.2.V indicates a complete discharge.
9. If the battery needs to be charged with an external charger, find the terminals for connecting this device in the rear right corner of the engine compartment and connect the charger wires to these terminals (pic. 3.9, a, b). If you are using an external quick charge device or if you are not sure. If you know the type of charger, remove the battery from the vehicle and charge it according to the manufacturer's instructions.
