The Victron 12V 115Ah AGM Telecom battery is a deep cycle, valve-regulated lead-acid battery built for standby and cyclic duty in demanding installations. It uses threaded M8 insert terminals for torque-controlled, vibration-resistant connections, and weighs 36 kg.

Key features

• Capacity, 12V nominal, 115Ah, giving 1.38 kWh of nominal stored energy.
• Construction, AGM (Absorbent Glass Mat), sealed and maintenance-free, spill-proof for flexible mounting orientation.
• Terminals, M8 threaded inserts for bolted cable lugs and secure torque connections.
• Duty, deep cycle rated for repeated charge and discharge, not just float standby.
• Grade, telecom-specification build, manufactured to tighter tolerances than standard leisure or automotive AGM batteries.
• Design, valve-regulated (VRLA), no water topping required, reduced gassing in normal use.

Product overview

The telecom designation reflects consistency in capacity, internal resistance and cycle life, which matters where failure has direct operational consequences. The M8 threaded inserts allow proper torquing of terminal connections, reducing contact resistance and the risk of loose joints over time.

Usable capacity depends on discharge rate and the depth of discharge set on the connected charge controller or inverter. It works with Victron chargers, inverter-chargers and MPPT solar charge controllers that include AGM charge profiles. The sealed case allows installation in enclosed spaces, though ventilation is still recommended.

At 36 kg, two people or lifting equipment are needed for installation. Terminal connections should use correctly rated cable lugs torqued to the M8 specification.

Applications

• Telecommunications infrastructure backup power
• Off-grid solar storage with Victron MPPT charge controllers
• UPS and critical standby power systems
• Marine and motorhome house battery banks needing deep cycle capability
• Industrial and commercial backup installations
• Multi-battery 12V, 24V or 48V bank configurations, series or parallel

Installation notes

Fit by a qualified electrician or experienced solar installer. Use correctly rated M8 cable lugs torqued to specification. When forming banks, match batteries by age, capacity and type, and set the charge controller to the AGM profile.
