When we can ensure that automotive engine battery is fail?

1, more difficult than usual to start: if the new car stage, no other factors, suddenly found that the start-up difficulties, may be China automotive truck car engine battery and battery box is about to be scrapped for a precursor. Start-up noise: because China automotive truck car engine battery and battery box discharge capacity is weak, the starter is not running well and squeaking, battery manufacturers introduce this situation is particularly obvious at low temperatures, because the weather is cold, battery activity will be reduced, and after the weather warms up such a situation will improve or disappear, so many car owners do not care.

2, before and after the start of voltage changes: the normal battery voltage of about 12V, and after start-up due to generator charging, the voltage will be increased to about 13-14V, many vehicles with voltage detection function, pay attention to the start-up voltage is also a good means to judge battery life, the vehicle is not started below 12V or less than 13V after start-up, should consider whether China automotive truck car engine battery and battery box has a problem. Battery fault warning light on: fault light on, it is recommended that the owner go to 4S or repair shop to check the replacement.

3, idle when the headlights suddenly dim: such as red lights or temporary parking, headlights suddenly dim. This is because at idle speed, the charging power of the engine decreases, if China automotive truck car engine battery and battery box is not powered at this time, but also to power the electric equipment in the car, then the power rationing of the headlights outside the car will be greatly reduced. Battery drum bag, leakage: mainly to see whether China automotive truck car engine battery and battery box leakage or drum bag situation, if such a situation should be replaced in a timely manner, such a situation brings not only China automotive truck car engine battery and battery box life problem, or even have a certain security risk.
