xVictron Energy 12V 90Ah AGM Deep Cycle Battery (M6 Terminals)
The Victron Energy 12V 90Ah AGM Deep Cycle Battery is a sealed, maintenance-free lead-acid battery designed for cyclic applications in solar, off-grid and marine systems. It uses absorbed glass mat (AGM) technology with M6 threaded insert terminals, making it well suited to professional installations where secure, bolt-down connections are required.
Key Features
- 12V nominal voltage with 90Ah capacity, suitable for a wide range of off-grid and backup power applications.
- AGM (Absorbed Glass Mat) construction: sealed, valve-regulated and maintenance-free with no risk of acid spillage.
- M6 threaded insert terminals provide a secure, vibration-resistant connection compared to standard post terminals.
- Deep cycle design built to withstand repeated charge and discharge cycles, unlike standard standby or starter batteries.
- Victron Energy manufacture, with consistent quality control and compatibility with the full Victron charging and monitoring ecosystem.
- Weight of 22.5 kg reflects a high-density lead plate construction typical of quality deep cycle AGM batteries.
Product Overview
AGM batteries immobilise the electrolyte within a fibreglass mat separator, which eliminates free liquid acid and allows the battery to be installed in any orientation (except inverted). This also makes them safe for use in enclosed spaces such as battery compartments in boats, caravans and off-grid cabins, where vented flooded batteries would require additional ventilation provisions.
The deep cycle rating distinguishes this battery from automotive or UPS standby types. It is designed to be regularly discharged to a meaningful depth and recharged, making it appropriate for solar storage, inverter backup and similar cyclic duties. The M6 threaded inserts accept standard M6 bolts, allowing cable lugs to be fastened directly and securely without relying on clamp-style connectors that can loosen over time.
This battery is compatible with Victron chargers, inverter/chargers and battery monitors, and can be configured and monitored through the Victron ecosystem. When used with a Victron MPPT or inverter/charger, the correct AGM charge profile should be selected to maximise cycle life.

Installation Notes
This battery should be installed by a qualified electrician or experienced system integrator. Ensure the charge source (solar charger, inverter/charger or mains charger) is set to the correct AGM charge profile before connecting. When building a battery bank, use batteries of the same age, capacity and manufacturer. M6 bolts and correctly rated cable lugs must be used at the terminals; do not overtighten, as this can damage the threaded inserts. Install in a well-ventilated location as a precaution, even though AGM batteries produce minimal gas under normal operating conditions. Dispose of or recycle lead-acid batteries in accordance with UK WEEE and hazardous waste regulations.
