Battery testers provide an easy way for hardware designers and hobbyists to determine the genuine capacity of Ξ²atteries. There are different makes and models being sold across diverse online stores but one which stands out among all that I have used in recent times is theΒ ZKETECHΒ EBD-A20H.
ZKE, over the years, has produced some interesting battery testers like the handyΒ EBD-MO5, but theΒ EBD-A20HΒ is probably the most versatile and professional looking one Iβve seen.
Spotting the kind of professional look that will fit right on the workbench in any lab (Professional or DIY home lab), theΒ ZKETECH EBD-A20HΒ is essentially a DC electronic load with multiple, controlled, battery discharge modes, that can be used to conduct various battery capacity and other power-related tests.
Some specifications of theΒ EBD-A20HΒ include:
- Power Supply: DC 12V/1A
- Voltage Setting: 0.00-30.00V, minimum step is 0.01V
- Current Setting: 0.1-20.00A, minimum step is 0.01A (Current automatically limits when power is overrun)
- Test mode: DSC-CC: constant discharge current for testing battery capacity or supply current/ DSC-CP: Constant discharge power for simulating constant power equipment or testing power supply
- Voltage Test: 0.000-4.500V (low pressure) accuracy to 0.003V, error Β±0.5% / 4.50V-30.00V (high pressure) accuracy to 0.01V, error Β± 0.5%
- Current Test: 0.10-20.00A, accuracy to 0.01A, error Β± 0.5%
- Capacity Test: Within 10Ah, resolution is 0.001Ah/ 10Ah-100Ah resolution is 0.01Ah/ Above 100Ah resolution is 0.1Ah
- Discharge Power: Max 200W (It should be controlled within 90% for a long time working)
To make the visualization and analysis of test data easier, asides theΒ LED displayΒ where the test data including voltage, current, capacity, time, power, energy, are displayed, the device also works with the βEB softwareβ which precisely displays and can be used to plot curves, perform calibration benchmark tests, automatic current testing and also push firmware upgrades to the Battery tester device.
