The automotive battery tester is a professional measuring tool mainly for car batteries.
For the car, although the car battery does not account for a high proportion of the cost, it plays a decisive role in the entire car.
Traditional method to test battery health
The traditional way to test the health of a battery is to discharge. The current actual capacity of the battery is detected by discharging to test the health of the battery. For car batteries, the International Battery Institute (BCI) stipulates that the battery should be discharged for 15 seconds (CCA) at 1/2 of the rated cold start current value at room temperature. If the battery voltage is above 9.6V, the battery has passed the discharge test , Is a healthy battery.
Insufficient performance of traditional battery test methods
1. The battery under test must be fully charged, at least 12.4V, but the fully charged voltage is not constant. Since the test principle is discharge, it will inevitably lead to changes in the measurement results;
2. For the same battery, continuous repeated measurement is not possible, and the test data may have reading errors. Because of the discharging process, the tested battery must be recharged after the test before it can be measured again;
3. A large amount of heat is emitted during the test, and continuous testing must be matched with a heat sink;
4. The test process requires the tester to be well-trained, because the voltage value of the battery must be read at the moment of discharge for 15 seconds, which will affect the test conclusion.
A better way to test batteries: automotive battery tester
The battery tester is a multi-functional battery maintenance and inspection equipment, and it is an indispensable helper for the daily maintenance of the battery. The equipment is small in size and easy to move and operate. The battery tester has high power, small size, light weight, friendly and humanized human-computer interaction interface, which greatly reduces the workload of daily battery testing and maintenance, and is a good assistant for battery maintenance.
