High Rate Max Series (MR) by C&D Technologies: A Comprehensive Overview

The C&D Technologies High Rate Max (MR) Series is a line of high-performance, Valve-Regulated Lead (VRL) batteries engineered for critical standby power applications. Leveraging advanced Absorbent Glass Mat (AGM) technology, these batteries deliver reliable, high-rate discharge power essential for Uninterruptible Power Supplies (UPS), data centers, and other systems requiring dependable short-duration backup.

The High Rate Max (MR) series is designed for maximum reliability and performance in demanding environments. Its core features focus on safety, longevity, and operational flexibility.

  • Valve-Regulated Lead (VRL) Technology: Features a sealed, maintenance-free design that immobilizes electrolyte in an Absorbent Glass Mat (AGM). This allows for efficient gas recombination, preventing the need for water addition and enabling installation in any orientation.
  • Optimized for High-Rate Discharge: Engineered to deliver high currents for short durations, making it ideal for bridging power gaps in UPS systems until utility power is restored or generators are activated.
  • Extended Design Life: Offers a long service life of up to 10 years in standby float applications at 25°C (77°F), ensuring a low total cost of ownership.
  • Enhanced Safety Features: Equipped with patented, UL-recognized flame-arresting vents and housed in a flame-retardant (FR) polypropylene case, enhancing operational safety.
  • Durable, Leak-Proof Construction: A thermally welded case-to-cover bond ensures a leak-proof seal, protecting sensitive electronic equipment and ensuring battery integrity.
  • Broad Operational Range: Capable of operating over a wide temperature range, from -40°C to +71°C (-40°F to +160°F).
  • Global Standards Compliance: Not restricted for transport by air, surface, or water, complying with IATA/ICAO, DOT-CFR, and IMDG regulations.
