It is built for solar storage, marine, and off-grid systems where a standard AGM battery would degrade prematurely under repeated heavy cycling. 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\u003e12V nominal voltage with 125Ah capacity, suitable for medium to large off-grid and backup power systems.\u003c\/li\u003e\n  \u003cli\u003eAGM Super Cycle chemistry tolerates deeper and more frequent discharge cycles than standard AGM batteries, extending service life in demanding applications.\u003c\/li\u003e\n  \u003cli\u003eM8 threaded insert terminals allow the use of bolted cable lugs for a reliable, low-resistance connection.\u003c\/li\u003e\n  \u003cli\u003eAbsorbent Glass Mat (AGM) construction is maintenance-free, spill-proof, and can be installed in any orientation except inverted.\u003c\/li\u003e\n  \u003cli\u003eVictron Energy manufacture, backed by consistent quality control and wide compatibility with Victron charge controllers, inverter-chargers, and battery monitors.\u003c\/li\u003e\n  \u003cli\u003eWeight of 32.5 kg reflects the substantial lead content that underpins the battery's capacity and cycle performance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eStandard AGM batteries are rated for a limited number of deep discharge cycles before capacity begins to fall significantly. The Super Cycle range addresses this by using a modified plate design and electrolyte formulation that allows repeated discharge to lower state-of-charge levels without the same degree of sulphation and plate degradation. This makes the 125Ah Super Cycle a practical choice for solar systems where the battery may be drawn down daily, or for marine and vehicle applications where shore power is not always available.\u003c\/p\u003e\n\n\u003cp\u003eAt 12V and 125Ah, this battery provides a nominal 1.5 kWh of stored energy. In practice, usable capacity depends on the depth of discharge you operate at and the charge voltage settings on your system. Victron's own charge controllers and inverter-chargers include preset charge profiles for AGM batteries, which simplifies commissioning. If you are using a third-party charger, ensure it supports AGM chemistry and that absorption and float voltages are set correctly for 12V AGM.\u003c\/p\u003e\n\n\u003cp\u003eThe M8 threaded inserts are a practical detail that matters in professional installations. They accept standard M8 cable lug bolts, eliminating the risk of terminal damage from over-tightening that can occur with post-type terminals. This is particularly relevant in mobile and marine environments where vibration is a factor.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: BAT412112081\u003c\/li\u003e\n  \u003cli\u003eNominal Voltage: 12V\u003c\/li\u003e\n  \u003cli\u003eCapacity: 125Ah\u003c\/li\u003e\n  \u003cli\u003eBattery Type: AGM Super Cycle\u003c\/li\u003e\n  \u003cli\u003eTerminal Type: M8 threaded insert\u003c\/li\u003e\n  \u003cli\u003eWeight: 32.5 kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076041832\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 storage systems with daily charge and discharge cycles.\u003c\/li\u003e\n  \u003cli\u003eMarine house battery banks where deep cycling is routine.\u003c\/li\u003e\n  \u003cli\u003eMotorhome and campervan leisure battery installations.\u003c\/li\u003e\n  \u003cli\u003eUPS and backup power systems subject to regular discharge events.\u003c\/li\u003e\n  \u003cli\u003eTelecom and remote monitoring equipment with solar charging.\u003c\/li\u003e\n  \u003cli\u003e12V battery banks wired in series or parallel for higher voltage or capacity systems.\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 125Ah AGM Super Cycle Battery (M8 terminals)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThis battery weighs 32.5 kg. Ensure adequate structural support in the installation location and use appropriate manual handling procedures. AGM batteries must not be charged with a charger set for flooded (wet) lead-acid chemistry, as incorrect voltage settings will cause premature failure. For solar installations, set your charge controller to the AGM profile or configure absorption and float voltages to Victron's published values for this battery. Batteries installed in enclosed spaces should have adequate ventilation, as AGM batteries can vent gas under fault conditions. Installation in battery banks of more than one unit should be carried out by a qualified electrician to ensure correct cabling, fusing, and balancing. For grid-connected systems incorporating battery storage, consult a qualified installer regarding G98 or G99 compliance requirements.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59863658332494,"sku":"BAT412112081","price":259.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_BAT412112081_-_12V-125Ah_AGM_Super_Cycle_Batt._M8.webp?v=1781183005","url":"https:\/\/voltaconsolar.com\/products\/victron-12v-125ah-agm-super-cycle-battery-m8","provider":"VoltaconSolar","version":"1.0","type":"link"}
