The Victron 12V 200Ah AGM Telecom battery is a sealed, maintenance-free deep cycle battery for standby and cyclic duty. Built to telecom-grade standards, it suits off-grid, backup power and telecommunications installations that need reliable performance under sustained discharge. M8 threaded insert terminals give a secure, bolt-down connection for high-current cabling.

Key features of this AGM telecom battery

• Voltage and capacity, 12V nominal, 200Ah.
• Construction, AGM (Absorbent Glass Mat), sealed and valve-regulated, no electrolyte topping needed.
• Terminals, M8 threaded insert for a firm, vibration-resistant bolted connection.
• Duty rating, telecom-grade, built for repeated deep discharge cycles and extended float operation.
• Compatibility, works with the full range of Victron charge controllers, inverter/chargers and battery monitors.
• Weight, 58.5 kg.

Why the AGM design and M8 terminal matter

The glass mat separator holds electrolyte in suspension, so there is no free liquid and the battery can be positioned without spillage risk. This also lowers internal resistance, supporting higher charge and discharge currents than a flooded lead-acid battery of the same capacity.

The M8 threaded insert takes a bolt directly into the casing rather than a post-style clamp, giving a connection that resists loosening from vibration or thermal cycling. This is the standard approach in telecom cabinets and industrial UPS installations where connection integrity has to hold over long service periods.

Applications

• Telecommunications cabinet backup and standby power.
• Off-grid solar storage at 12V, 24V or 48V using series or parallel wiring.
• Industrial UPS and critical infrastructure backup.
• Marine and vehicle power systems needing a sealed, high-capacity battery.
• Remote monitoring stations, repeater sites and rural communications infrastructure.

Installation notes

At 58.5 kg, two people or mechanical handling equipment are needed to position this battery safely. Provide adequate ventilation per VRLA guidance, even though AGM batteries emit minimal gas in normal use. Use correctly rated M8 bolts and cable lugs torqued to the manufacturer's specification, and have a qualified electrician handle bank wiring, fusing and system integration. On solar PV or inverter/charger systems, confirm the charge voltage matches Victron's AGM profile to avoid overcharging or early capacity loss.
