Under normal use, the battery does not require recharging from external sources. Only during long periods of inactivity does the battery require recharging every 6 weeks. Recharging may also be required when using the car mainly for short trips in the dark. Otherwise, the need to recharge the battery indicates a fault in the battery or a fault in the charging circuit.
When charging with low current (for example, using a low-power charger), there is generally no need to disconnect the on-board electrical system connecting wires, but the ignition should be switched off and the bonnet left open. In any case, the charger manufacturer's instructions should be followed.
Before boost charging, which means charging with a high current, both wires connecting the battery to the on-board electrical system should be disconnected from the battery.
With any charging method, the temperature of the electrolyte in the battery should not exceed 38°C. If the battery becomes hot or vigorous gas evolution begins in the electrolyte, charging should be stopped.
Charging should be done with a constant current equal to 1/20 of the battery capacity.
The end of charging is indicated by the intensive release of gases from the battery and the fact that the density of the electrolyte does not change over the last 3 hours of charging.
Operation in winter conditions
In winter, the battery is under particularly heavy load. In addition, at low temperatures, the battery only gives a part of the power it has at positive temperatures when starting the engine. Therefore, we recommend checking the density of the battery electrolyte before the start of the winter season and recharging it if necessary.
If the car is not used for several weeks during very severe frosts, the battery should be removed and stored in a heated room so that it does not freeze and, as a result, is not destroyed.
If the battery was disconnected from the vehicle's electrical system and then reconnected to it.
After disconnecting the battery from the vehicle's electrical system, keep in mind that:
- all data from the trip computer's memory device is erased;
- all data from the driver's seat memory device is erased;
- watches with hands stop, watches with digital indication are out of order;
- the factory installed receiver is blocked;
- the automatic window lift and lower system with electric windows does not work.
After connecting the battery to the vehicle's electrical system, you must reset the clock.
Next, you need to restore the automatic operation of the full raising and lowering of the windows.
In addition, the driver's seat memory must be reinitialized, otherwise the adjustments will not be remembered.
The factory-installed radio can only be made operational by entering the appropriate code - see the "Radio User's Guide".
