Verzegelde VRLA-gelbatterij ARMAC BL/12V/120AH — 12 V 120 Ah, duurzaam

The ARMAC BL/12V/120AH is a sealed VRLA gel battery that delivers a nominal voltage of 12 V and a capacity of 120 Ah in a maintenance-free Long‑Life format. Designed for stationary energy storage, the gel electrolyte provides leak-free operation and improved tolerance to deep discharge and float service. The battery is intended for use in UPS systems, backup power installations, telecommunications sites and renewable energy setups where dependable long-term performance and low maintenance are required.

Advantages

The sealed VRLA gel construction eliminates the need for watering or regular electrolyte checks and reduces the risk of leakage. Gel electrolyte chemistry improves cycle life and enhances performance under partial-state-of-charge operation and in environments with variable temperatures. The Long‑Life design increases expected service duration in float applications, while the sealed casing allows installation in restricted or ventilated indoor spaces without special acid-proof containment.

Suitable for

• Uninterruptible Power Supplies (UPS) for servers and network equipment
• Standby backup systems for emergency lighting and building services
• Telecommunications base stations and routing equipment
• Renewable energy storage in solar or wind off-grid and hybrid systems
• Stationary energy storage where maintenance access is limited

Key specifications

• Nominal voltage: 12 V
• Nominal capacity: 120 Ah (at specified discharge rate)
• Battery type: Sealed VRLA with gel electrolyte
• Design: Maintenance-free Long‑Life
• Recommended installation orientation: upright or as specified by manufacturer for sealed gel cells
• Operating temperature range: suitable for typical indoor stationary installations (follow manufacturer temperature guidance)

How to use

Install the battery in a dry, ventilated indoor location on a stable, non-conductive surface or rack designed for lead-acid battery modules. Connect using appropriately rated cables and torque to the recommended terminal specifications provided by the system or battery manufacturer. Charge and manage the battery with a charger or charge controller compatible with sealed gel VRLA characteristics and configured for 12 V battery banks. Ensure correct float voltage settings for long-term standby use and avoid overcharge conditions to maximize service life.

Recommendations

For best long-term performance, operate the battery within the recommended float and charge voltage windows for gel VRLA cells, maintain ambient temperatures within the range advised by the manufacturer, and use a charger with temperature compensation if the installation experiences seasonal temperature variation. Periodically inspect terminals and connections for corrosion and ensure secure mounting; record voltage and specific system test results to detect capacity decline early.
