The service life of a car battery is generally 3 years，During the conventional maintenance of the car，Auto Maintenance Technician Union for inspection，Tell the car owner if you need to change。But the specific situation still depends on the owner's driving habit，There are also new cars less than a year，The battery is lost for electricity，This also has a lot to do with driving habits。
When encountering the following situations，The owner's friends must Seabetpay attention，Your car battery will need to be replaced ~
1
Difficulty in starting a car When there are no other factors，If the car loves suddenly starts difficulties，That may be a precursor that the battery is about to fail，But if it is winter, it may be the so -called cold start difficulty。
2
When the car idle, the lights darkened. .......................................................................For example, when the red light or temporary parking，Love car headlights suddenly darkened。This is because the charging power of the engine decreases during idling，If the battery is almost used at this time，At the same time, it is necessary to supply power to other equipment in the car，The electricity consumption of car headlights is large，There will be insufficient power supply，Caused the light to darkens。
3
Battery fault light light .......................................................................When the battery fault light is on，That is to remind the owner，I should go to the maintenance plant for battery maintenance and detection。
4
A abnormal noise occurs when starting ...........................Due to weakened battery discharge capacity，The starter will make a poor operation and squeaks，This situation is particularly obvious at low temperature，Because the weather is cold，The activity of the battery will also be reduced，and the weather will be improved or disappeared，So many car owners don't care。
5
Battery observation hole There is an observation hole on the battery exemption seabet appbattery，Observe the light of the hole show whether the battery work is good，Green is good，Black needs to change the battery，However, some car owners also reflect that this light is not reliable，Obviously green cannot start a car，Observation hole as a simple reference。
