How to judge the battery.portable energy storage battery power supply wholesaler

release time:2023-05-06 Hits: Popular:AG11 battery

1) Judging from the appearance, observe whether there is deformation, bulge, leakage, fracture, explosion, carbonization, oxide seepage, etc. at the threaded connection

(2) If the appearance of the on load measurement is normal, the UPS operates in the battery mode under a certain load. If the discharge time is obviously shorter than the normal discharge time, the normal standby time cannot be recovered after 8 hours of charging, and the battery is judged to be aging

(3) Using the battery analyzer to test a simple battery tester can only measure the battery voltage under high current discharge, and roughly judge the storage capacity of the battery. At present, in addition to starting discharge, more advanced battery detectors can accurately measure cold starting current (CCA), such as wdkr-j battery discharge monitor

The operation method is as follows:

1. When in use, connect the battery detector with the battery for 10~15 seconds, and keep the voltage at 10.5~11.6v, indicating that the capacity is sufficient and the battery is free of failure

2. If the voltage is kept at 9.6 V~10.5 V, it means that the capacity is insufficient and the battery is free of fault

3. If the voltage drops below 9.6 V, it indicates that the capacity is seriously insufficient or the battery is faulty
