Sealed Lead-Acid Battery Alarmtec BP3.6-12 12V 3.6Ah AGM for Backup Power and Alarm Systems

Sealed AGM lead-acid battery Alarmtec BP3.6-12 is a compact 12V 3.6Ah battery designed for reliable backup power in alarm systems, UPS units, emergency lighting and small uninterruptible power supplies. Its valve-regulated AGM construction is maintenance-free and provides low self-discharge, stable output and safe operation in multiple orientations. The battery is suitable for installation where a compact, sealed 12V power source is required for security and low-power industrial applications.

Advantages

The battery offers a sealed, maintenance-free design that eliminates the need for periodic electrolyte checks. AGM (Absorbent Glass Mat) technology ensures reduced gassing and stable voltage under typical standby and cyclic loads. Low self-discharge extends shelf life and reduces the need for frequent recharging during storage. Its compact dimensions and upright or side mounting capability allow flexible installation in confined enclosures common to alarm panels and small UPS systems.

Suitable for

• Alarm and security systems
• Small UPS and backup power modules
• Emergency and exit lighting
• Low-power industrial control units and detectors
• Replacement battery for compact 12V assemblies

Key specifications

• Nominal voltage: 12 V
• Capacity: 3.6 Ah (at the standard discharge rate)
• Battery type: Sealed lead-acid, AGM (valve-regulated)
• Maintenance: Maintenance-free, no electrolyte refilling required
• Orientation: Can operate in multiple orientations (upright or side-mounted) due to sealed construction
• Self-discharge: Low self-discharge for extended storage life
• Typical applications: Standby and cyclic use in low-power backup systems

How to use

Install the battery in the device compartment according to the equipment manufacturer’s instructions, ensuring correct polarity and secure terminal connections. Charge the battery with a compatible 12V lead-acid charger or the host device's charging circuit, following recommended charging voltages and current limits for sealed AGM batteries. For initial use, fully charge before placing into continuous standby service. Periodically verify terminal tightness and device charging status during routine maintenance checks.

Usage recommendations

Store the battery in a cool, dry place and avoid prolonged exposure to temperatures outside the manufacturer’s recommended range. For reliable backup performance in alarm and UPS systems, maintain a regular inspection schedule and replace the battery when capacity falls below system requirements or based on the expected service life for sealed lead-acid batteries in your application.
