Description

The NEWARE A705-CR-MA-DG is a dedicated coin cell clamp designed for stable and reliable button cell testing. Its 4-wire Kelvin structure helps minimize the influence of contact resistance during measurement, while the gold-plated contact surface provides a durable electrical interface. With a contact resistance of ≤50 mΩ at 100 mA, the clamp is suitable for precision battery testing applications. Its operating temperature range of −40 to 150°C also allows coin cells to be tested under a wide range of temperature conditions. The rail self-locking mechanism enables convenient installation and positioning, while the robust construction provides a service life of more than 20,000 cycles, making the A705-CR-MA-DG suitable for repeated battery R&D and laboratory testing.
