How to Check How Much Power is Left in a Car Battery?
1 Answers
Here are the methods to check the power level of a car battery: 1. You can directly press the horn; if the horn is not as loud as before, it indicates insufficient battery power. 2. You can turn on the headlights for inspection; if the light is bright white, the battery is normal, but if the light is dim and reddish, it means the power is low. 3. Additionally, there is a battery warning light on the dashboard; if this light stays on, it means the battery power is insufficient and needs to be replaced promptly. 4. You can also observe the feedback when starting the car; if the car struggles to start, it is likely due to a weak battery.
