Features:1.Battery Capacity Test2.This tester is designed for charging and discharging of a wide range of batteries, including NiMH, NiCd, LiPo, LiFe and Pb, as well as the capacity test.3.Portable Power Bank Test4.This tester supports charging and discharging of portable power banks, as well as capacity test.5.Power Performance Test6.This tester supports performance and aging tests of various kinds of DC power supplies.Specifications:Power Supply: DC 12V/3.5A or aboveVoltage Range: 0-30.00V, stepper 0.01V (In charging the maximum voltage can be set 10V)Current Range in charging and discharging: 0.050-5.000AFor charge, 0.050-3.000A, stepper 0.01AFor discharge, 0.050-5.000A, stepper 0.01A (In discharging process current will adjust automatically when power exceeds limits.)Charging mode:Standard Charging: Support NiMH, NiCd, LiPo, LiFe and Pb batteriesCHG-CV: Current and voltage can be set at a constant voltage (only for batteries) during dischargingDischarging mode:DSC-CC: Discharging batteries at a constant current, support testing battery capacity or current of power suppliesDSC-CP : Discharging batteries at a constant power, for constant power equipment-like use or testing powerMeter function: the tester can be used to measure voltage and current (only supported by mode of A05+). A+/A- is current meter, and V+/V- is voltage meter.Automatic Charging/Discharging: The tester supports “charging-discharging-charging” circles for capacity tests.Voltage accuracy: between 0-4.5V, 0.003V, ±0.5%, between 4.5-30V, 0.01V, ±0.5%.Current accuracy: 0.01-5.000A, 0.005A, ±0.5%.Capacity detection: < 10Ah,0.001AH; 10-100Ah,0.01Ah; > 100Ah,0.1AhFour lines: voltage and current channels separated for high test accuracyLCD Display: voltage, current, time, capacity, power, energy, and etcPC Connection: The tester can be connected to a computer through a designated USB-TTLcable to have more functions.Note:There are two main differences between A05 and A05+: Using an A05 tester the maximum current you can set in charging and discharging batteries is 0.08A, while A05+ allows 0.05A. Only A05 tester supports stable voltage output while A05+ supports Meter function.
