Rechargeable Sealed Lead Acid (VRLA) Battery Green Cell AGM42 — 12 V, 2800 mAh, 0.84 kg

Green Cell AGM42 is a rechargeable Sealed Lead Acid (VRLA) battery with a nominal voltage of 12 V and a capacity of 2800 mAh. The maintenance-free, valve-regulated design delivers stable power for a range of devices including UPS systems, security and alarm equipment, industrial electronics and other backup applications. The compact black housing and lightweight construction (0.84 kg) make installation and replacement straightforward in confined spaces.

Advantages

The AGM42 uses Sealed Lead Acid (VRLA) technology that combines reliable energy storage with minimal maintenance requirements. Valve-regulated construction prevents electrolyte leakage and reduces the need for monitoring, while AGM separators improve vibration resistance and enable consistent performance in cyclic and standby use. Its compact size and moderate weight simplify mounting in cabinets, enclosures and portable systems.

Suitable for

• Uninterruptible Power Supply (UPS) units and backup power modules
• Alarm systems, security devices and access control panels
• Industrial control equipment and monitoring devices
• Cyclic applications such as small electric toys and portable equipment
• General-purpose backup for telecommunications and measurement instruments

How to use

Install the battery in a well-ventilated, dry location and secure it to prevent movement. Connect using the correct polarity and matching terminals; ensure connectors are tight and free of corrosion. For standby (buffer) operation, keep the battery connected to the charging system that provides the recommended float voltage for VRLA batteries. For cyclic use, follow a charging regimen suitable for AGM batteries to avoid deep discharge and to prolong service life. Observe manufacturer guidelines for charge current limits and temperature ranges.

Usage recommendations

To maximize service life, maintain appropriate float charging when used in backup systems and avoid prolonged storage at low state of charge. Store and operate the battery within recommended temperature ranges, avoid mechanical damage, and replace the battery once capacity falls below the level required by your application. For safety, follow local regulations for disposal and recycling of lead-acid batteries.
