The EA‑BT 20000 Triple battery tester integrates three 10kW channels in a single 4U unit. Each channel can run independent battery tests for faster throughput or be combined to provide higher current for demanding test scenarios.

The EA‑BT 20000 Series battery tester delivers accurate voltage and current measurements with external sense, minimizing errors from voltage drops—especially at high currents. Triple-channel models and 1ms communication accelerate bench and automated testing, while active pre-charge, cable/connection checks, and overload protection reduce downtime and keep your battery testing running smoothly.

The EA‑BT 20000 Series battery tester features autoranging, delivering maximum power across a wide range of voltages and currents—even down to 33% of the rated output. Unlike traditional power supplies, which only reach full power at maximum voltage and current, autoranging ensures your battery tester maintains full output under real-world conditions. This allows a single tester to handle multiple voltage and current combinations, eliminating the need for multiple power supplies and streamlining battery testing workflows.

EA‑BT 20000 battery testers with regenerative technology recover up to 96% of the energy used during testing. Instead of wasting power as heat like traditional loads, recovered energy is fed back into the local grid—or even the public grid—reducing facility costs and improving test efficiency.

Water-cooled EA‑BT 20000 models ensure stable operation in harsh industrial environments, efficiently dissipate heat, reduce noise, and maintain reliability under challenging conditions.
