Before performing any procedure that involves disconnecting/connecting the battery, refer to the electrical section of this manual entitled "Disconnecting/Connecting the Battery". For additional information, refer to the chapter: Specifications (414-01 Battery, Battery Mounting and Cables, Specifications).
A discharged battery may be caused by a short circuit in the electrical circuit. If the battery is discharged, it is likely that there is always an electrical circuit in the car that is under voltage even with all electrical circuits off. This can cause sparking when connecting the jumper cables.
Although it is not recommended to start the engine using connecting wires (jumpers), we still recognize that sometimes this may be the only practical way to get the car moving. Before attempting to start the engine with connecting wires (jumpers), please read the electrical equipment section of this Manual entitled "Starting the engine with connecting wires (jumpers)".
After starting the faulty engine, using connecting wires (jumpers), it is necessary to check the serviceability of the battery as soon as possible and charge it by removing it from the car.
If you want to restore a dead battery, do not rely on the alternator. It will take more than eight hours of continuous driving without any other additional load on the battery to charge the battery from the alternator.
Always ensure that the connecting wires are suitable for the intended purpose.
The auxiliary battery voltage should always be the same as the vehicle battery voltage (meaning nominal characteristics). The batteries should be connected in parallel.
Switched electrical circuits must be disconnected before connecting the connecting wires. This reduces the risk of sparking during final connection.
