The Maccor Series 4000, 4000H, and 6500 are the global benchmark for automated battery testing — trusted by the world's leading researchers, manufacturers, and quality engineers for cycle life, performance, and qualification testing.
Maccor's cell and module test systems set the standard for automated battery testing worldwide. With a presence in over 50 countries and more than 1,000 facilities — from the world's largest EV manufacturers to leading university research labs — the Series 4000 platform is the reference against which all other battery cyclers are measured.
Every system ships as a complete, turn-key solution. Configurable from one to 96 channels, with current outputs from milliamps to 2,400A, and power to 28,800W per system — there is a Maccor configuration for every application from coin cell electrochemistry to full EV module qualification.
All systems run the same MacTest32 software platform, ensuring protocol portability across your entire fleet — from a bench-top desktop unit to a 96-channel production rack.
Three platform configurations covering the full range of battery test applications — from single-cell R&D to multi-channel module qualification.
The most widely deployed battery test platform in the world. Covers everything from coin-cell electrochemistry to large-format module testing with configurable 1 or 4 current ranges and the full options suite.
Doubles the power envelope of the standard 4000, supporting up to 2,400A and 28,800W per system. Built for high-current module and pack testing where realistic charge/discharge profiles at full power are essential.
Maccor's next-generation platform delivering 3,200A per channel and 16,000W in a compact footprint. Designed for high-power EV module and pack testing where current density, speed, and accuracy define the result.
Maccor's High Density Cell tester provides all of the features and benefits of the industry standard Series 4000 in a compact design.
Every design decision in the Series 4000 platform is driven by the requirements of professional battery test labs.
Four-range channels deliver sub-microamp resolution at the bottom range — essential for materials research, electrochemical characterization, and small-cell work where accuracy defines the science.
Minimum step times from 2ms enable accurate dynamic profiles and HPPC testing. The hardware executes the protocol as written — no approximations, no step-time inflation.
MacTest32 runs identically on every Maccor system. Build a test procedure on a desktop tester and run it unchanged on a 96-channel rack — protocols, data formats, and analysis tools are the same.
Auxiliary voltage, temperature, pressure, CAN, SMBus, EIS multiplexer, digital I/O, and external charge/discharge controllers — every meaningful interface for real-world test integration.
Add channels, expand options, or upgrade software modules as your requirements grow. Maccor systems are designed for long-term operation — not planned obsolescence.
Every Maccor system is backed directly by the engineers who designed it. When you call Maccor, you reach the factory — not a reseller, not a call center.

Learn More →The Series 4000 supports up to 96 channels at 1,400A and 14,400W with 1 or 4 current ranges, making it the standard choice for cell and small-module testing. The Series 4000H is the high-power variant, supporting up to 96 channels at 2,400A and 28,800W with 2 or 3 current ranges — designed for high-current module and pack testing where you need to test at full operating power levels.
The Series 4000 and 4000H support 1 to 96 channels per system, configurable at time of order. Multiple systems can be networked together through MacTest32 for larger-scale test programs. The Series 6500 supports 1 to 8 channels per system.
All Maccor systems — Series 4000, 4000H, 6500, desktop units, and FUSION systems — run MacTest32, Maccor's proprietary test control software. Test procedures, data files, and analysis tools are fully portable across every system in your fleet. There is no retraining required when you add a new system or upgrade your platform.
The Series 4000 and 4000H offer minimum step times of 2ms, 5ms, or 10ms depending on configuration. The Series 6500 has a minimum step time of 10ms. Fast step times are essential for accurate HPPC testing, dynamic profiles, and characterization work where the hardware must execute the protocol as written — not approximated.
Yes. Maccor systems with the temperature monitoring option support direct thermocouple integration for logging and test-flow branching. For a fully integrated and pre-validated solution, the FUSION Integrated System combines a Maccor cycler, thermal chamber, and safety controls in a single turnkey package — deployed and tested as a unit before leaving the factory.
Maccor battery test systems are deployed in over 50 countries across more than 1,000 facilities worldwide — from the world's largest EV and consumer electronics manufacturers to leading university research programs and national laboratories. The Series 4000 platform has been in continuous production since 1987, making it the longest-running and most widely trusted battery test platform in the industry.
