Stable Energy Storage, Long-Life Maintenance-Free Design

I. Product Overview

The German BEINING FCG series valve-regulated sealed lead-acid batteries are high-performance battery product lines specifically designed for backup power and energy storage applications. This series incorporates advanced AGM separator technology and a unique lead-calcium-tin multi-element alloy grid formulation, offering excellent high-rate discharge performance, low self-discharge, and long service life. The product range covers a complete capacity range from 7Ah to 150Ah, meeting various backup power and energy storage requirements.

FCG series products feature a fully sealed construction. During charging, most of the oxygen generated inside the battery is absorbed and reduced by the plates, resulting in virtually no acid mist emission. They are safe, environmentally friendly, and can be installed in office environments or equipment rooms without the need for a separate battery room.

III. Core Technical Advantages

Maintenance-Free Design

The battery features a valve-regulated sealed construction. During charging, most of the oxygen generated inside is absorbed and reduced by the plates, resulting in virtually no electrolyte loss. No water addition or specific gravity checks are required throughout the entire service life, achieving true maintenance-free operation.

High Sealing Reaction Efficiency

Advanced gas recombination technology achieves a sealing reaction efficiency exceeding 99 percent. No acid mist is emitted during charging, making the battery safe, environmentally friendly, and suitable for indoor use.

Low Self-Discharge Rate

Using specialized high-purity lead alloy grids, the self-discharge rate is controlled within three percent per month at 20℃ ambient temperature. The battery requires no frequent supplementary charging during storage, reducing maintenance workload.

Long Service Life

Featuring corrosion-resistant lead-calcium alloy grids, the normal float service life can reach 10 years at 25℃ ambient temperature.

Excellent High-Rate Discharge Performance

With low internal resistance plates and fiberglass separators combined with tight assembly technology, the battery exhibits low internal resistance and excellent high current discharge performance.

Strong Deep Discharge Recovery Capability

The combination of specialized high-porosity, high-wet-elasticity fiberglass separators and tight assembly technology ensures strong over-discharge tolerance.

Easy Installation and Use

The battery is fully charged when shipped from the factory and can be installed and put into use immediately without the need for additional activation or initial charging steps.

• Storage environment should be dry and clean, with temperature between -20℃ and 40℃

• Fully charge batteries before storage

• Recommended supplementary charge every 3-6 months for long-term storage

• Avoid mixing with metal objects to prevent short circuits

IX. Periodic Inspection and Maintenance

Although the FCG series is maintenance-free, periodic inspection every 6-12 months is recommended:

• Check battery case for swelling, cracks, or leakage

• Check terminals for corrosion or looseness, keep terminal surfaces clean

• Measure individual cell float voltage

• Check connecting cables for aging or damage

• Remove dust and dirt from battery surfaces
