xVictron Energy 12V 220Ah AGM Deep Cycle Battery (M8 Threaded Terminals)
The Victron Energy 12V 220Ah AGM Deep Cycle Battery is a sealed, maintenance-free lead-acid battery designed for demanding cyclic applications. With M8 threaded insert terminals and a 220Ah capacity, it suits off-grid solar systems, marine installations, motorhomes and backup power setups where reliable deep cycling is required.
Key Features
- 12V nominal voltage with 220Ah capacity, providing substantial energy storage for off-grid and backup applications.
- AGM (Absorbent Glass Mat) construction: sealed, valve-regulated and maintenance-free with no need to top up electrolyte.
- M8 threaded insert terminals allow secure, torque-controlled connections and reduce the risk of terminal damage during installation.
- Deep cycle design built to withstand repeated charge and discharge cycles, unlike standard standby or starter batteries.
- Victron Energy manufacture, ensuring compatibility with the full range of Victron charge controllers, inverter/chargers and battery monitors.
- Weighs 62.5 kg, reflecting the high-density plate construction typical of a genuine deep cycle AGM at this capacity.
Product Overview
AGM batteries use a fibreglass mat to absorb and immobilise the electrolyte, which eliminates acid spillage risk and allows installation in any orientation (except inverted). This makes them well suited to marine, vehicle and enclosed cabinet installations where a flooded battery would be impractical or unsafe. The sealed construction also means no hydrogen venting concerns under normal operating conditions, though adequate ventilation is still good practice in enclosed spaces.
The 220Ah capacity at 12V gives a nominal 2.64kWh of stored energy. In practice, usable capacity depends on the depth of discharge you apply. AGM batteries are typically cycled to 50% depth of discharge to preserve cycle life, giving approximately 1.3kWh of usable energy per cycle. For higher usable capacity or longer cycle life, multiple units can be connected in parallel (12V systems) or series-parallel configurations for 24V or 48V banks. Victron's Battery Monitor range allows accurate state-of-charge tracking across multi-battery banks.
The M8 threaded insert terminals are a practical advantage over standard bolt-on posts. They accept M8 bolts directly into the battery casing, allowing a flat, low-profile connection without the risk of cracking a post by over-tightening. This is particularly useful in vibration-prone environments such as marine or vehicle installations.

Installation Notes
At 62.5 kg, this battery requires two people or mechanical handling equipment to move and position safely. Use M8 bolts of appropriate length and apply the correct torque to the threaded terminals; do not over-tighten. When building a battery bank, use cables of equal length and cross-section to ensure balanced charging and discharging across all units. AGM batteries must be charged with a charger or inverter/charger set to the correct AGM voltage profile; using a flooded or gel profile will shorten battery life. Installation in enclosed spaces should include adequate ventilation. For solar or off-grid system integration, a qualified electrician or MCS-accredited installer is recommended.
