The service life of a car battery is 3 years commonly when the car is maintained routinely, the union of automobile maintenance technician makes an inspection, tell the owner whether to need to change. But specific circumstance still depends on the driving habit of the car owner and decide, also have a new car less than a year, the battery is deficient of, this also has a very big concern with driving habit.
When encountering the following situations, the owners of small partners will pay attention to your car battery will need to be replaced oh ~
1. The car has difficulty starting
In the absence of other factors, if the car is suddenly difficult to start, it may be the battery is about to fail, but if it is winter may be the so-called cold-start difficulty.
2. The lights dimmed when the car was idling.
For example, when you are at a red light or stop temporarily, your car's headlights suddenly go dark. This is because the charging power of the engine drops when the engine is idle. If the battery can't be used at this time, and other devices in the car need to be powered at the same time, the headlights of the car will consume a large amount of power, and the power supply will be insufficient, resulting in dimming of the lights.
3. Battery failure light is on
When the battery failure light on, that is to remind the owner, should go to the repair shop for battery maintenance test.
4. The abnormal sound occurs during startup
Because the discharge capacity of the battery is weak, the startup machine will appear bad operation and squeak, this situation is particularly obvious at low temperatures, because the weather is cold, the battery activity will be reduced, and the weather will be improved or disappear after the warm, so many car owners do not care.
5. Battery observation hole
There is an observation hole on the maintainable battery, the lamp of the observation hole shows whether the battery works well, green is good, black needs to replace the battery, but some car owners will also reflect that the lamp is not reliable, is clearly green can not start the car, the observation hole as a simple reference.
6. The surface of the battery appears to bulge and leak
This situation is mainly to see whether there are a bulge and leakage of the battery if found such a situation, please timely replacement, if not replaced, there will be a safety risk, remember to be replaced.
In addition to the normal working voltage of 12 v battery, when start charging generator, voltage will rise to about 13 to 14 v, a lot of cars with voltage check function, focus on starting voltage change before and after, to identify the battery is good or bad, if the vehicle is not start was less than 12 v or start after less than 13 v, that we should consider the battery problem.
