Description
xVictron Energy 12V 165Ah AGM Telecom Deep Cycle Battery (M8 Terminals)
The Victron Energy 12V 165Ah AGM Telecom battery is a deep cycle valve-regulated lead-acid (VRLA) battery designed for demanding standby and cyclic applications. With M8 threaded insert terminals and a 165Ah capacity, it is suited to telecom infrastructure, off-grid power systems, and any installation where a reliable, maintenance-free battery is required.
Key Features
- 12V nominal voltage with 165Ah capacity, providing substantial energy storage in a single unit.
- AGM (Absorbent Glass Mat) construction: sealed, valve-regulated, and completely maintenance-free.
- M8 threaded insert terminals allow secure, high-torque bolt connections suitable for professional installations.
- Deep cycle design supports repeated charge and discharge cycles without premature capacity loss.
- Telecom-grade specification, built to perform in continuous standby and float charge applications.
- Spill-proof and leak-proof construction permits installation in any orientation (except inverted).
- No off-gassing under normal operating conditions, making it safe for use in enclosed or ventilated battery enclosures.
Product Overview
AGM batteries use a glass mat separator to hold the electrolyte in place, eliminating free liquid inside the cell. This makes them inherently safer than flooded lead-acid batteries and removes the need for periodic water top-ups. The sealed construction also means they can be installed in locations where ventilation is limited, provided the enclosure meets the manufacturer's requirements for the specific application.
The telecom designation reflects a higher standard of construction and cycle life compared to standard standby AGM batteries. These batteries are engineered for applications where the battery may experience regular partial or full discharge cycles, such as off-grid solar systems, UPS installations, and remote telecommunications equipment. The M8 threaded inserts provide a more secure and lower-resistance connection than standard bolt-on terminals, which is important in high-current applications and anywhere vibration or repeated maintenance access is expected.
At 48.8 kg, this is a heavy unit and will require appropriate handling equipment and structural support in the installation location. Batteries of this capacity are typically installed in banks to achieve higher voltage or greater total energy storage, and cable sizing, fusing and battery management should be specified accordingly.

Installation Notes
Installation should be carried out by a qualified electrician or accredited installer familiar with lead-acid battery systems. At 48.8 kg, safe manual handling requires at least two people or appropriate lifting equipment. Ensure the installation surface and any racking or enclosure are rated to support the weight of the full battery bank. M8 terminal bolts should be torqued to the manufacturer's specification to avoid terminal damage or poor contact. Batteries must not be installed in fully sealed, unventilated spaces. For solar PV and off-grid systems, a compatible Victron charge controller or inverter-charger should be configured with the correct AGM charge profile. Do not mix batteries of different ages, capacities or chemistries within the same bank.
