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.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e12V nominal voltage with 220Ah capacity, providing substantial energy storage for off-grid and backup applications.\u003c\/li\u003e\n  \u003cli\u003eAGM (Absorbent Glass Mat) construction: sealed, valve-regulated and maintenance-free with no need to top up electrolyte.\u003c\/li\u003e\n  \u003cli\u003eM8 threaded insert terminals allow secure, torque-controlled connections and reduce the risk of terminal damage during installation.\u003c\/li\u003e\n  \u003cli\u003eDeep cycle design built to withstand repeated charge and discharge cycles, unlike standard standby or starter batteries.\u003c\/li\u003e\n  \u003cli\u003eVictron Energy manufacture, ensuring compatibility with the full range of Victron charge controllers, inverter\/chargers and battery monitors.\u003c\/li\u003e\n  \u003cli\u003eWeighs 62.5 kg, reflecting the high-density plate construction typical of a genuine deep cycle AGM at this capacity.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eAGM 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.\u003c\/p\u003e\n\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: BAT412201085\u003c\/li\u003e\n  \u003cli\u003eNominal voltage: 12V\u003c\/li\u003e\n  \u003cli\u003eCapacity: 220Ah\u003c\/li\u003e\n  \u003cli\u003eBattery type: AGM Deep Cycle, sealed VRLA\u003c\/li\u003e\n  \u003cli\u003eTerminal type: M8 threaded insert\u003c\/li\u003e\n  \u003cli\u003eWeight: 62.5 kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076037095\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eOff-grid solar energy storage in residential, agricultural or remote site installations.\u003c\/li\u003e\n  \u003cli\u003eMarine house battery banks for sailing yachts, motorboats and canal boats.\u003c\/li\u003e\n  \u003cli\u003eMotorhome and campervan leisure battery systems.\u003c\/li\u003e\n  \u003cli\u003eUninterruptible power supply (UPS) and backup power for telecoms or critical equipment.\u003c\/li\u003e\n  \u003cli\u003e12V, 24V or 48V battery banks when wired in series or parallel combinations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x Victron Energy 12V 220Ah AGM Deep Cycle Battery (M8 threaded terminals)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eAt 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.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59863039344974,"sku":"BAT412201085","price":376.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_BAT412201085_-_12V-220Ah_AGM_Deep_Cycle_Batt._M8.webp?v=1781175051","url":"https:\/\/voltaconsolar.com\/products\/victron-12v-220ah-agm-deep-cycle-battery-m8","provider":"VoltaconSolar","version":"1.0","type":"link"}
