Yes, but you can only turn on one battery.
The battery of a 24 volt truck is made up of two 12 volt batteries connected in series, in this way the nominal voltage reaches 24 volts, however, if the battery is not broken but only loses. power, then both batteries are exhausted at the same time, so using a 12 volt battery to start the fire will have little effect.
If one of the batteries malfunctions and the voltage is too low, a 12 volt battery can be used to turn on a single power battery to start the vehicle.
Detailed informationPrecautions for starting a fire in a vehicle:
1. The battery connection wire used should be thick wire. The current when starting the car is very important. the wire is too thin, it will cause the wire to overheat.
2. When building a fire, make sure the positive poles and bornconnections match. Do not connect the positive and negative poles backwards. cause damage to the electronic components of the vehicle, or even the disposal of the battery.
3. After starting the car, the power generated by the car's generator is not enough to fully charge the battery. The vehicle must be charged with a charger to avoid repeating this problem the next time it is started. .
Do not use 220 V to directly connect the battery. Direct connection will damage the battery.
When the car battery is discharged, you can use the following methods to start the car.
1. Trolley starting is the most well-known and effective emergency starting method, but it is a last resort and cannot be used frequently. Because it will cause certain damage to the engine and clutch, automatic vehicless should especially avoid using this method to start.
2. In order to avoid not being able to charge when the battery is dead, you can use a cable connection to start. First connect the positive terminal of the discharged battery to the positive terminal of the emergency vehicle battery. , then connect the negative terminal of the emergency vehicle battery. The terminal is connected to a metal part (ground wire) inside the dead car engine. Once the jumper cable is connected, you can start the emergency vehicle's engine and slightly increase the engine speed. After about 5 minutes, you can emergency charge the discharged battery.
3. Battery life is typically 2-3 years. After this period, car owners should pay special attention to the daily maintenance of the battery and replace it in time if necessary to avoid danger.
Detailed information:
The battery is more afraid of low temperatures. Temperature environment, the battery power capacity is much lower than the capacity at room temperature. Therefore, we should check and maintain in time, and pay attention to the following points in daily life:
1. Avoid parking the car in an open-air parking lot for a long time. for a long time, the battery should be removed and removed to prevent damage from freezing.
2. The car engine is not easy to start in winter. The car starting time should not exceed 5 seconds each time, and the interval between restarts should not be less than 15 seconds. If the fire still does not start after several starts, you need to check the circuit, ignition coil or oil circuit and other reasons. Avoidstart several times without interruption, as this may cause the battery to drain due to excessive discharge.
3. The car battery should be charged frequently. If the battery is not used for a long time, it will discharge slowly until it is discarded. Therefore, the car must be started from time to time. to charge the battery.
4. Clean the battery terminals from time to time and apply special grease to protect the wiring harness. Always check accessories and connection lines on the battery.
5. It is prohibited to use car electrical appliances after the car is turned off. Using the battery alone when the engine is not generating electricity will damage it.
