The car battery is dead. What signal does the dashboard show?

The car battery is dead, and the battery indicator light on the dashboard is always on.

There will be a battery-like symbol on the dashboard, with a plus sign on one side and a minus sign on the other. When the vehicle is running, it will charge the battery. If the symbol of low battery power appears during long-term driving, it means that the battery has been damaged or cannot be recharged, and it is necessary to check and replace the battery in time.

Ways to avoid battery dead:

1, don't forget to turn off the lights and car appliances. Turning off the lights in the car before parking is a common mistake made by many novice drivers, especially the headlights of the car consume a lot of electricity, especially the batteries that have been used for a long time, which may be dead at any time, so try not to use CD, cigarette lighter and other electrical equipment when the car is not started, and use less various on-board appliances when driving.

Turn off the air conditioner before turning off the fire. Many car owners are used to not turning off the air conditioner or letting the air conditioner automatically start with the start of the vehicle, which will directly drive the air conditioning system after the vehicle is ignited, increasing the working intensity of the air conditioning system, and the instantaneous power load of the vehicle is too high, which is a loss to the battery for a long time.

3. Don't start the vehicle frequently. Do not start the engine for more than 3 seconds at a time. If the first startup fails, don't restart it repeatedly, and the interval between restarting it should be more than 5 seconds.
