Designed specifically for telecom applications and data centers, GEMBATTERY GF Series Front Terminal Batteries deliver reliable 12V backup power with a space-efficient front-terminal design. Using advanced AGM technology, thick Pb-Ca-Sn plates, and optimized deep-discharge performance, the GF Series provides long-lasting and dependable power for telecom towers, data centers, UPS systems, renewable energy, and industrial backup applications.
Front-terminal batteries, also known as “narrow” batteries, are designed for space-constrained telecom cabinets and rack systems. With the terminals positioned at the front, the GF Series enables easier installation, connection, inspection, and maintenance while making better use of valuable equipment-room space.
Advanced AGM Technology & Reliable Construction
The GEM GF Series adopts advanced AGM (Absorbent Glass Mat) technology. The new AGM separator supports efficient internal gas recombination and centralized venting, while helping maintain reliable operation in compact battery configurations.
High-quality Pb-Ca-Sn thicker plates are assembled with a special chemical formation process to enhance durability and support long-term float operation. Flame-retardant ABS case material is also available for applications with higher safety requirements.
Strong Deep-Discharge Performance
The GF Series is designed with an innovative battery plate formula optimized for deep discharge applications. Key advantages include:
Excellent recharge acceptance after deep discharge
Extremely low self-discharge
Low internal resistance
Low internal pressure
Long-life assembly with thicker plates
These features help provide stable performance for backup systems that may remain on standby for extended periods but must deliver reliable power when an outage occurs.
Space-Efficient Front Terminal Design
The front-terminal configuration is particularly suitable for modular cabinet and rack systems. By providing convenient front access, the GF Series simplifies installation and maintenance while helping optimize the available space in telecom rooms and data centers.

The GF Series is designed for a variety of critical and renewable energy applications, including:
Telecom & tower power assurance
Data centers
Sizable UPS systems
High-performance UPS systems
Medical power assurance
Solar PV & wind power systems
Off-grid power systems / power plants
Industrial battery & power reserve
General-purpose backup power
The GEMBATTERY GF Series combines compact front-terminal access with advanced AGM technology and durable battery construction. Its low self-discharge, strong deep-discharge capability, excellent recharge acceptance, and long float service design make it suitable for demanding backup power environments.
