ALM 12V7 Battery System

ALM 12V7

ALM® 12V7s

Lightweight, Long-Lasting Replacements for Lead-Acid Batteries

The ALM 12V7s product line delivers exceptional performance, operating life, and robust safety in the most demanding energy storage applications.  Designed to deliver high power delivery with consistent energy capacity, leading cycle and float life, and robust safety protections, the ALM 12V7s products are ideal for demanding UPS, telecommunications back-up, and medical equipment power systems.

High Performance

  • High power delivery up to 9C while maintaining full rated capacity, ideal for small, short duration UPS applications.
  • Fast charging, allowing full charge from 100% discharge depth in less than 10 minutes, dramatically improving the availability of portable devices such as medical equipment

Long Life

  • Exceptional cycle life even at repeated deep, fast operating cycles, opening the possibility of batteries outlasting the equipment they serve.
  • Superior float service and calendar life, virtually eliminating the need for battery servicing and replacement in most back-up power applications.

Tough, Critical Applications

  • Consistent performance across temperature extremes, dramatically outperforming even temperature-optimized lead-acid batteries in demanding environments, such as telecom outside plant equipment.
  • Lightweight – less than half the weight of equivalent lead-acid batteries – simplifying use in portable equipment or outside equipment.
  • Simply scalable in series up to 48V and in parallel configurations for expanded capacity, without external controls

Robust Safety

  • EverSafe™ Battery Technology. providing built-in, fully redundant, electronic fusing and sensing protection against short circuits, over-voltage, over-current, and over-temperature conditions, with automatic recovery.
  • Tested and proven against the latest UL and IEC standards for assured safety.
  • Inherently safe, abuse tolerant, Nanophosphate® LiFePO4 chemistry.
