Victron Energy 12V 220Ah Deep Cycle AGM Battery

The Victron Energy 12V 220Ah Deep Cycle AGM Battery is engineered for reliable, continuous power delivery in demanding off-grid, marine, and mobile applications. Built using Valve Regulated Lead Acid (VRLA) technology, this battery features Absorbent Glass Mat (AGM) construction, which holds the electrolyte securely within a fibreglass mat. This design requires no routine maintenance and provides excellent deep cycle capabilities with a design life of 7 to 10 years under optimal conditions.

With its exceptionally low internal resistance, the Victron AGM range is highly suited to high-current discharge applications. Whether you are running heavy-duty inverters, marine thrusters, or 4x4 winches, this battery is capable of delivering the sustained power required without experiencing severe voltage sag.

Advanced Construction and Safety

Victron has constructed this battery with high-purity materials and lead-calcium grids. This combination results in a very low self-discharge rate, allowing the battery to be stored for extended periods, such as during caravan off-seasons or boat layups, without going completely flat. When stored in a cool environment, the battery can typically be left for months before requiring a top-up charge.

Safety and compliance are paramount in off-grid power storage. The battery is housed in an ABS fireproof container, providing robust physical protection and helping to mitigate fire risks. It is compliant with both CE and UL specifications, meeting strict international safety standards for electrical storage.

Key Features and Specifications

• High-Current Delivery: Exceptionally low internal resistance makes it well suited for running heavy loads like inverters and winches.
• Extended Design Life: Offers a 7 to 10-year design life in float service, providing reliable long-term power.
• Low Self-Discharge: High-purity lead-calcium grids ensure the battery maintains charge during long periods of inactivity.
• M8 Flat Copper Terminals: Integrated M8 drilled terminals ensure maximum contact area for cables, eliminating the need for separate battery terminal adapters.
• Robust Enclosure: Encased in an ABS fireproof container for enhanced safety and physical resilience.
• Sealed Construction: VRLA AGM design requires no watering or routine electrolyte maintenance.

Installation and Setup

The battery is supplied with M8 drilled, flat copper terminals. This hardware configuration ensures the best possible connection contact, reducing electrical resistance at the terminal block and supporting safe high-current draws. Because the AGM design is sealed and spill-proof, it offers greater flexibility in mounting orientation compared to flooded lead-acid batteries, although upright installation is always recommended for optimal heat dissipation and terminal access.

To maximise the lifespan of your Victron AGM battery, it is essential to use a high-quality, multi-stage battery charger tailored for AGM charging profiles. Incorporating proper voltage regulation and temperature compensation helps prevent premature capacity loss and ensures the battery delivers its full rated cycle life.
