Description:
DK500 is the portable lead-acid batteries rapid tester that can quickly judge the status of a single battery by detection of the voltage difference of open-circuit voltage and discharge terminal voltage, and can also record the voltage difference of each battery to judge the equalization of the whole battery group, The device is suitable for preliminary rapid judgment of battery status and equalization.
DK500 can quickly determine the condition of the battery and the balance of the entire battery pack, which greatly improves the efficiency of testing and maintenance. It is an essential testing tool for electric vehicles and battery maintenance & after-sales service.
Applicable Batteries: 6V, 12V, 16V Batteries
Compact Product Size: 265 * 92 * 55mm

Function:
- Discharging current 20A/25A/30A/35A/40A/45A/50A for selection
- Discharging time 30"/60"/90"/120" for selection
- Test data of 6pcs of batteries can be recorded
- Minimum test voltage: 5V
- Quickly judge the battery status by testing voltage difference of open-circuit voltage and final voltage, and can also record the voltage difference of each battery to judge the equalization of the entire battery group.
- Keep pressing the reset key to clear the data.
The selection of the test current and time:
The Max. discharging current 20A/25A/30A/35A/40A/45A/50A for selection,
The discharging time 30"/60"/90"/120" for selection.
Taking the 12V VRLA battery as a sample:
1. The Test Current is selected to 30A and the Test Time is selected to 30s when the open-circuit voltage(Initial Voltage) is in 11.5V-12.0V around.
2. The Test Current is selected to 50A and the Test Time is selected to 60s when the open-circuit voltage(Initial Voltage) is in 12.0V-12.5V around.
3. The Test Current is selected to 50A and the Test Time is selected to 60s when the open-circuit voltage(Initial Voltage) is greater than 12.5V.(Notes: Sometimes the voltage of the battery with a higher open-circuit is stable during the first test, so one more time test is needed, the voltage change of the bad battery will appear in the second test)
Remarks:
The discharging current and discharging time of this device is selected according to the open-circuit voltage of the tested battery, and then judges the status of the battery by comparing the voltage difference between the initial voltage before the test and the cut-off voltage after the test. The accuracy is above 90%.
Judgment Criterion:
If the voltage difference between the Initial Voltage before test and the Cut-off Voltage after test >=2V, the tested battery can be judged as a doubtful battery, it can be returned to the manufacturer.
If the voltage difference between the Initial Voltage before test and the Cut-off Voltage after test <2V, the tested battery can be judged as a good status battery, it is recommended to process the charging and discharging detection again to make the final checking.
Warning:
This device is only applicable for the detection of the 6V/12V/16V single battery, to test the battery pack is strictly prohibited!
