How long is the cycle life of the car's emergency starting power supply?

Whether it is a mobile power source, a power source, or a battery, everyone cares about how long it lasts and how long it can last. The lifetime of a battery can be measured using the number of cycles it discharges. In order to measure how long the car can be used for an emergency power supply battery, the definition of the number of cycles is defined. The actual users use the ever-changing, because the tests with different conditions are not comparable, and for comparison, the cycle must be standardized. Definition of life.mobile power plant

The national standard stipulates the cycle life test conditions and requirements for the battery of the car emergency starting power supply: charging at a room temperature of 25°C for 150 minutes in a constant current and constant voltage mode 1C charging system, and discharging to a constant current 1C discharge system to 2.75V as a cycle When the discharge time is less than 36 minutes, the test is completed and the number of cycles must be greater than 300.

Explanation:

A. This definition stipulates that the test of cycle life is conducted in a deep-charge deep-discharge mode.

B. Specifies the cycle life. The capacity must still exceed 60% after more than 300 times after execution in this mode.

Another measure of cycle life is time. Some experts pointed out that the general DOCA automobile emergency starting power supply battery is often used in the case of automotive emergency starting power battery is 2 to 3 years, combined with the actual situation, such as 60% of the capacity for the end of life, plus the car emergency start The aging effect of the power battery, and then not everyone has a professional knowledge of it, so popular point, a car emergency starting power cycle life is generally about 2-3 years. Therefore, the user does not have to worry about the problem that the power supply he has purchased has a short service life.
