Product Details

✓Premium Capacity Testing Solution: The ZB2L3 Battery Capacity Tester delivers professional-grade performance with DC4.5-6V USB power supply and supports discharge testing from 1.00V to 15.00V. Featuring automatic current tracking technology that maintains ±2mA accuracy even at minimal 20mA loads, this external load type tester measures up to 9999Ah capacity range with 0.001A current resolution and less than 1% voltage measurement error, making it suitable for precise battery performance evaluation in workshops and laboratories.

✓Intelligent Auto-Configuration Technology: Experience hassle- operation with the For auto- function that automatically calculates optimal termination voltage based on your battery's full-charge state. The blue metal and plastic construction (50mm*37mm*17mm) houses advanced circuitry supporting up to 3.000A continuous current flow. Manual override option allows termination voltage settings from 0.5V to 11.0V with 0.1V resolution, providing flexibility for testing various battery chemistries including lithium-ion, NiMH, and -acid configurations.

✓Real- Data Display System: your battery's discharge process through dynamic cycling between three critical parameters: accumulated capacity in Ah (displayed as X.For XX below 10Ah, For XX.For XX above), instantaneous discharge current in amperes, and live voltage readings. The high-contrast digital display automatically switches decimal positions for readings exceeding 10Ah, while For rapid-flash indicators with corresponding LED signals you immediately when testing completes at your preset termination voltage threshold.

✓Safety-First Design Features: Built with reinforced power interface connections that resist accidental disconnection during extended cycles. The electronic switching mechanism automatically cuts off the load circuit upon reaching termination voltage, protecting both your batteries and connected resistive loads from over-discharge damage. Compact 50mm*37mm circuit board fits easily into technician toolkits while consuming less than 70mA operating current, insuring reliable performance without draining your USB power source.

✓Testing Package: Includes 1 ZB2L3 Battery Capacity Tester unit ready for immediate deployment. Guaranteeing compatibility with resistive loads up to 3A (note: use inductive- loads only; lamp loads limited to 1.5A due to cold-resistance surge characteristics). The device guides you through four simple steps from full battery charge through data collection to capacity readout, with OK/+/- buttons enabling intuitive navigation through setup and operation modes for testing multiple batteries consecutively.
