1. TK15 is a kind of high precision current type battery capacity tester(also known as coulometer),which can test the voltage,current and capacity of battery to help users know the state of battery in time. TK15 has memory function. It is suitable for mobile and portable equipment.e-bike.balance car,cleaning machine,instrument,ups and so on.2. Application: TK15 is suitable for lithium battery,lithium iron phosphate battery ,lead-acid battery and nickel-metal hydride battery, which working voltage is from 8V to 100V.3. The empty and full voltage of battery can be adjusted.The backlight automatic open when using.Automatic memory function when down.Fast response rate.Low consumption, automatic wake-up.4. Display: Residual capacity of battery (Ah or mAh). Capacity percentage and pole display. Battery voltage. Battery current. Powe output.
