Digital Battery Capacity Tester 18650 Lithium Polymer Resistance Voltage DetectorTwo types for you to choose:Type 1: Basic testerType 2: With test backetFeatures:Voltage: 5V \/ Micro USB phone chargingCan accurately measure the lithium batteries、 nickel hydrogen batteries、 lithium iron capacityWith four gear (1A、 500MA、 330MA、 250MA) current test、 it can measure both high resistance battery and new battery.Measurement range: !#!amp!*!le;5V batteryThree display: Capacity display、 equivalent resistance display、 load voltage displaySuitable for all kinds of mobile phone batteries、 small-capacity battery testNote:1. New battery requires full charging、 fully charged lithium battery voltage is 4.2V.2. Battery capacity need to discharge to test、 need a period of time、 the lithium electricity test is 1 hour\/1 ah.3. In use、 only need to fully charge and then press K2、 the other is automatically (but must pay attention to the operation of step 6)4. When testing AA、 AAA batteries、 if the voltage is larger than 1.6V、 it can discharge by press K2、 or adjust the current to discharge、 discharge termination voltage is 1.2V. If the voltage is 1.5-1.59V、 it would need to boot by 1.2V NiMH batteries、 the first into the nickel-hydrogen discharge procedure、 and then discharge、 the discharge termination voltage is 1.0V (that is、 test the nickel-hydrogen battery first (a few seconds discharge、 then press K2 to stop discharge、 and then replace the nickel metal hydride batteries to dry battery、 press K2 discharge again.5. Measured with protection board battery、 need to test with a test stand、 the 18650 battery box is not suitable for with protection board batteries.6. Measuring lithium battery 1AH needs one hour discharge、 that is、 3000MAH lithium battery nees 3 hours to complete discharge.7. This product is only discharge function without charging、 charging also requires a dedicated lithium battery charger、 or charging module.Discharge current: automatically recognize the maximum current for the voltage range:4.8V-5.5V: 1000mA \/ 500mA3.6V-4.4V: 1000mA \/ 500mA \/ 333mA3.2V-3.5V: 1000mA \/ 500mA \/ 333mA \/ 250mA1.6V-1.9V: 400mA \/ 200mA \/ 133mA \/ 100mA \/ 80mA1.2V-1.5V: 333mA \/ 166.7mA \/ 111mA \/ 83.3mA \/ 66.6mATermination voltage:3.6V \/ 3.7V common lithium battery: 3.0V3.2V lithium iron phosphate battery: 2.5V1.6V nickel-zinc battery: 1.2V1.2V NiMH battery: 1.0VPackage includes:Type 1:1 x Battery Capacity TesterType 2:1 x Battery Capacity Tester1 x Test bracket
