A 24 volt battery cannot be started when it is lower than 12 volts, because when the vehicle starts, there is a large current for an instant, and the starting voltage needs to be higher than the minimum voltage when the computer is working. If the battery is below 12 volts, it is in a state of power loss, and a large current can not be sent out in an instant, and the voltage is lower than the minimum voltage of the computer when it is started, so that the vehicle cannot be started.
If the battery fails to start, and the engine cannot be started and the battery cannot be charged, temporary measures can be taken to deal with it. If you want to know whether the battery is losing power, you can see whether it is on on the car dashboard. You can also use the batteries on other vehicles to start the car, as long as you ask other vehicles for help, and then connect the batteries on the two cars with the negative pole and the positive pole to the positive pole.
How to use car battery longer
1. When driving the vehicle, the battery will be charged, and the owner who needs to park for too long should start the engine regularly to avoid the battery loss due to the long-term parking of the vehicle;
2. Clean the terminal on the battery every once in a while, and apply special grease to protect the wiring harness, and check the accessories and connection lines of the battery regularly;
3. Try not to use on-board electrical appliances after the car is turned off. The battery is used alone when the engine is not generating electricity, which will easily cause the battery to lose power.
