Scope of Application: This battery capacity tester is mainly used for test the capacity of battery, check for better using experience!2. LCD Display: The 1.77in screen displays internal resistance, capacity, voltage, current, power and other information at the same time.3. Modes Adjustable: Preset automatic and charging and discharging modes, and select corresponding modes after starting.4. Data Reset: The power off, mode switch will make the data capacity, energy and time data automatically reset.5. Working Instructions: Some components will produce local high temperature during charging and discharging during use. Please ensure that the use environment is open and of cover. It is better to increase fan heat dissipation. In order to ensure that the battery clamp is firm, the battery tester is more suitable for flat head battery measurement.6. DIY Transformation: Firstly, add battery holder. Then, connect the battery outside the extension cable or clip for testing.Spec:Item Type: Battery Internal Resistance TesterMaterial: PCBScreen Size: Approx. 1.77in / 4.5cmWorking Power Supply: DC5V power supply or battery x 2 (shipped without battery)Applicable Battery: Suitable for all batteries that meet the requirements of stopping discharge voltage of 2.5-3.5V and starting from 2.8V to 4.2VPower Supply Interface: Type C interface, power supply line self prepared (C port mobile phone line) System Language: Chinese (default), EnglishTest Quantity: 1 way charging and discharging measurement (only right battery position)Internal Resistance Measurement: Support, use DC two wire method to test internal resistanceCharging Function: Support, automatic cut off charging when fully charged (lithium iron battery charging is not supported)Discharge Function: Support, automatically stop when conditions are met, and the discharge current is not adjustableAutomatic Charging and Discharging: ProductSiteLaunchDate : 2023-11-06T15:54:25.720Z
