Sealed AGM Rechargeable Battery Green Cell CSB-44.5/AGM36 4V 4.5Ah

Sealed AGM Rechargeable Battery Green Cell CSB-44.5/AGM36 4V 4.5Ah is a compact valve-regulated lead-acid (VRLA) cell designed to provide reliable standby and portable power. With a nominal voltage of 4 V and a rated capacity of 4.5 Ah, this maintenance-free battery is built for applications that require spill-proof operation, long shelf life and consistent performance in periodic or continuous float service.

Advantages

The sealed AGM construction uses absorbed glass mat technology to immobilize the electrolyte, preventing leakage and allowing installation in virtually any orientation. As a rechargeable lead-acid unit it supports multiple charge/discharge cycles, offers good shelf stability and requires no water topping or regular maintenance. Its compact dimensions and low self-discharge make it suitable for systems with limited space and intermittent use.

Suitable for

• Uninterruptible power supplies (UPS) for small systems
• Emergency lighting and exit signs
• Alarm and security systems
• Portable measurement and monitoring devices
• Backup power for communication equipment and controllers

Key specifications

• Nominal voltage: 4 V
• Capacity (rated): 4.5 Ah
• Technology: sealed AGM (valve-regulated lead-acid)
• Design: rechargeable, maintenance-free
• Orientation: spill-proof for flexible mounting
• Typical applications: standby and cyclic use

How to use

Install the battery in a clean, dry location with adequate ventilation and secure mounting to prevent movement. Connect using appropriate connectors and polarity-aware wiring; verify that the host device supports a 4 V battery and the required capacity. Charge the battery before first use following the charger manufacturer’s recommendations for sealed lead-acid/AGM batteries. Avoid deep discharge beyond recommended limits to prolong cycle life.

Usage recommendations

For optimal performance, store the battery charged and recharge every 6–12 months if kept in storage. Use a compatible float/standby charger with voltage and current limits suitable for sealed AGM cells, and avoid charging at excessively high temperatures. Dispose of the battery according to local regulations for lead-acid batteries.
