Lead-acid battery FM series

12 V6 Vfor emergency lighting

Overview
Designed for cyclic and deep-discharge applications, this battery series uses advanced alloy and paste formulations to support extended charge/discharge cycles. The cells employ AGM VRLA technology with a sealed, maintenance-free construction and can be installed in any orientation.

Application Scenarios

• Telecom and power equipment
• Emergency lighting and fire-safety systems
• Security systems, office IT equipment
• UPS and backup power devices
• Portable power units, robotics and control systems

Key Features

• High cycle life — plate design and materials optimized for frequent deep cycling
• Enhanced safety — large thermal capacity reduces risk of thermal runaway and limits electrolyte drying
• High energy density — maximizes stored energy in constrained spaces
• Strong deep-discharge tolerance — maintains stable performance under repeated deep cycles
• Reliable long-duration discharge — consistent power output for extended operation
• Dual-purpose use — applicable for both backup power and energy storage systems

Industry Applications

• UPS & AIDC battery solutions
• Telecom battery solutions (site backup, base stations)
