Powerful Backup Solution: GEM Brand GDC12-28 12V 28Ah AGM-GEL Maintenance-Free Lead Acid Battery
Core Advantages for Industrial Applications
As a reliable partner for critical infrastructure, the
GDC12-28 battery combines cutting-edge technology with robust design, delivering unmatched performance in demanding environments:

-
Dual-Technology Innovation
- Leverages AGM-GEL hybrid technology to seal electrolyte in glass fiber mats and gel, ensuring 100% leak-proof operation and support for vertical/horizontal installation.
- Ideal for remote or hard-to-access sites (e.g., outdoor communication towers) where maintenance is challenging.
-
Exceptional Deep Discharge Recovery
- Even after discharging to 20% of rated capacity, the battery rapidly recovers via standard charging-critical for systems with frequent power outages.
- Outperforms conventional batteries in cyclic applications, reducing downtime and replacement costs.
-
Longevity & Low Maintenance
- Thickened lead alloy plates with special corrosion-resistant treatment extend cycle life to 5-8 years in deep discharge scenarios (30% longer than standard models).
- Ultra-low self-discharge rate (<3%/month at 25ºC) minimizes storage losses, making it suitable for long-term backup stockpiles.
-
Safety & Stability
- Low internal resistance enables high-current discharge (e.g., 3C rates) for instant power support in UPS systems.
- Certified by UL/IEC 60896, with explosion-proof valve design to prevent pressure buildup, ensuring compliance with global safety standards.
