How do you know the battery is broken?
The battery is one of the core components of automobiles, electric vehicles and other equipment. Once it fails, it may directly affect the normal use of the equipment. So, how to tell if the battery is broken? The following is a summary of battery failures in hot topics across the Internet in the past 10 days to help you quickly identify battery problems.
1. Common symptoms of battery failure

When there is a problem with the battery, it usually shows the following symptoms:
| Symptoms | possible reasons |
|---|---|
| Difficulty starting | The battery is insufficient or aging |
| Dashboard lights dim | Battery voltage is unstable |
| Battery bulges or leaks | Internal battery damage |
| Vehicle stalls frequently | Battery power supply is unstable |
| Charging speed slows down | Battery capacity decreased |
2. How to detect whether the battery is damaged
If you suspect there is a problem with the battery, you can check it by the following methods:
| Detection method | Operation steps |
|---|---|
| voltage test | Use a multimeter to measure the battery voltage. The normal value should be around 12.6V. |
| load test | Observe whether the voltage drops suddenly when starting the vehicle. If it is lower than 9.6V, there may be a problem. |
| Appearance inspection | Check whether the battery is bulging, leaking or corroded |
| Charging test | The battery cannot be maintained after charging, indicating that the battery is aging. |
3. Countermeasures for battery failure
If the battery is confirmed to be damaged, you can take the following measures:
| Question type | solution |
|---|---|
| Low battery | Try charging or powering up |
| Battery aging | Replace with new battery |
| Battery leaking | Stop using and replace immediately |
| Wiring corrosion | Clean the electrodes and apply anti-corrosion agent |
4. How to extend the service life of the battery
In order to avoid premature battery damage, the following maintenance measures can be taken:
| Maintenance method | Specific operations |
|---|---|
| Charge regularly | When the device is not used for a long time, charge it once a month |
| Avoid over-discharge | Charge in time when the battery is less than 20% |
| keep clean | Clean the battery surface and electrodes regularly |
| Check charging system | Make sure the charger or generator is working properly |
5. Precautions for battery replacement
If you need to replace the battery, please pay attention to the following points:
| Things to note | Description |
|---|---|
| Choose a matching model | Make sure the new battery matches the equipment parameters |
| Professional installation | Best to have it replaced by a professional |
| Recycle old batteries | Batteries are hazardous waste and need to be recycled professionally |
| Check circuit | Check the vehicle circuit after replacement |
Through the above methods, you can quickly determine whether the battery is faulty and take corresponding solutions. Regular inspection and maintenance of batteries can effectively extend their service life and avoid inconvenience caused by battery problems.
