DK BATTERY DISCHARGE CAPACITY TESTER BCT40

Lithium-ion & Lead-acid Battery Series Discharge Capacity Tester

Product Data Sheet

The Battery Discharge Capacity Tester BCT40 is a high-precision battery testing equipment designed to measure the actual discharge capacity (Ah) of lithium-ion, LiFePO4, and lead-acid battery packs. It performs controlled constant-current discharge testing to evaluate battery health, performance, and energy storage capability.

Widely used in EV battery manufacturing, energy storage systems, battery repair centers, and quality control labs, the BCT40 helps identify weak or degraded battery packs by measuring how much energy they deliver before reaching the cutoff voltage.

With a discharge current capability of up to 40A, the BCT40 is suitable for medium to high-capacity battery packs. It supports a wide voltage range and provides accurate, stable discharge performance, making it ideal for production testing and batch evaluation.
