It uses GEL electrolyte technology, making it maintenance-free and suitable for installations where ventilation is limited. The M8 threaded insert terminals provide a secure, vibration-resistant connection suited to professional installations.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e265Ah capacity at 12V nominal voltage, suitable for high-demand off-grid and backup power applications.\u003c\/li\u003e\n  \u003cli\u003eGEL electrolyte construction: sealed, maintenance-free and spill-proof, with no need for water topping.\u003c\/li\u003e\n  \u003cli\u003eM8 threaded insert terminals provide a firm, reliable bolted connection and resist loosening under vibration.\u003c\/li\u003e\n  \u003cli\u003eDeep cycle design supports repeated charge and discharge cycles, making it appropriate for daily solar cycling.\u003c\/li\u003e\n  \u003cli\u003eSealed construction allows installation in enclosed spaces where vented (flooded) batteries would not be permitted.\u003c\/li\u003e\n  \u003cli\u003eManufactured by Victron Energy, with consistent quality control across the range.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eGEL batteries immobilise the electrolyte in a silica-based gel, which eliminates the risk of acid spill and significantly reduces gassing during normal operation. This makes them a practical choice for installations inside caravans, boats, battery enclosures and off-grid cabins where a flooded battery would require dedicated venting. Compared to AGM batteries of similar capacity, GEL batteries generally tolerate slower, deeper discharges better, though they are more sensitive to high charge voltages. Correct charger settings are essential: use a charger or inverter-charger with a dedicated GEL charge profile.\u003c\/p\u003e\n\n\u003cp\u003eAt 265Ah, this battery provides substantial usable capacity. In a 12V system, assuming a 50% depth of discharge (a conservative figure that extends cycle life), you have approximately 1.59kWh of usable energy per battery. Multiple units can be connected in parallel to increase capacity, or in series pairs to build a 24V bank. At 73.1kg, this is a heavy unit and will require two people or mechanical assistance to position safely during installation.\u003c\/p\u003e\n\n\u003cp\u003eVictron's GEL Deep Cycle range is designed to work with the full Victron ecosystem, including MPPT solar charge controllers, MultiPlus and Quattro inverter-chargers, and the Venus GX monitoring platform. Ensure any charge source is configured to the correct GEL voltage parameters before commissioning.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: BAT412126101\u003c\/li\u003e\n  \u003cli\u003eNominal Voltage: 12V\u003c\/li\u003e\n  \u003cli\u003eCapacity: 265Ah\u003c\/li\u003e\n  \u003cli\u003eBattery Type: GEL Deep Cycle\u003c\/li\u003e\n  \u003cli\u003eTerminal Type: M8 threaded insert\u003c\/li\u003e\n  \u003cli\u003eWeight: 73.1kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076039587\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 cabins, outbuildings and remote installations.\u003c\/li\u003e\n  \u003cli\u003eMarine house battery banks where sealed, spill-proof construction is required.\u003c\/li\u003e\n  \u003cli\u003eMotorhome and caravan leisure battery systems.\u003c\/li\u003e\n  \u003cli\u003eUPS and backup power systems in commercial or industrial settings.\u003c\/li\u003e\n  \u003cli\u003eTelecoms and remote monitoring equipment with regular deep discharge cycles.\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 265Ah GEL Deep Cycle Battery (M8 terminals)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eAt 73.1kg, this battery must be handled with appropriate lifting equipment or by at least two people. Install on a surface rated to support the weight. Use correctly rated M8 bolts and cable lugs; do not overtighten terminals. Configure all charge sources (solar charge controllers, inverter-chargers, alternator regulators) to a GEL-specific charge profile before connecting. GEL batteries can be damaged by charge voltages set for AGM or flooded profiles. Battery installation in solar PV and off-grid systems should be carried out by a qualified electrician or MCS-accredited installer. Ensure the installation complies with BS 7671 wiring regulations and any applicable building or marine standards.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59863661216078,"sku":"BAT412126101","price":513.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_BAT412126101_-_12V-265Ah_GEL_Deep_Cycle_Batt._M8.webp?v=1781183029","url":"https:\/\/voltaconsolar.com\/products\/victron-12v-265ah-gel-deep-cycle-battery-m8","provider":"VoltaconSolar","version":"1.0","type":"link"}
