At 12V and 38Ah, it suits compact off-grid systems, marine installations, and mobile power setups where space and weight are a consideration. The M5 threaded insert terminals provide a secure, vibration-resistant connection.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e12V nominal voltage with 38Ah capacity, suitable for compact deep-cycle applications.\u003c\/li\u003e\n  \u003cli\u003eAGM Super Cycle technology tolerates deeper and more frequent discharge cycles than standard AGM batteries.\u003c\/li\u003e\n  \u003cli\u003eM5 threaded insert terminals provide a firm, reliable mechanical connection and resist loosening under vibration.\u003c\/li\u003e\n  \u003cli\u003eSealed, maintenance-free AGM construction with no free electrolyte, safe for use in enclosed spaces.\u003c\/li\u003e\n  \u003cli\u003eWeighs 9kg, making it manageable for single-person installation in mobile or marine environments.\u003c\/li\u003e\n  \u003cli\u003eManufactured by Victron Energy, with full compatibility with Victron charge controllers, inverter-chargers, and battery monitors.\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 degrades 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 rate of sulphation and plate damage. This makes the 38Ah Super Cycle a practical choice where daily cycling is expected, such as in campervans, narrowboats, or small off-grid cabins.\u003c\/p\u003e\n\n\u003cp\u003eThe M5 threaded insert terminals are a practical detail worth noting for installers. Unlike standard bolt-on posts, the threaded inserts allow a clean, torque-controlled connection that holds securely even in high-vibration environments. This reduces the risk of intermittent connections and terminal corrosion over time. The sealed AGM construction means no topping up is required and the battery can be mounted in any orientation except inverted.\u003c\/p\u003e\n\n\u003cp\u003eAt 9kg, this battery sits at a manageable weight for installation in tight spaces. It is compatible with the full range of Victron charging equipment, and Victron's Battery Protect and BMV battery monitors can be used to track state of charge and protect against over-discharge in unattended systems.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: BAT412038081\u003c\/li\u003e\n  \u003cli\u003eNominal Voltage: 12V\u003c\/li\u003e\n  \u003cli\u003eCapacity: 38Ah\u003c\/li\u003e\n  \u003cli\u003eTerminal Type: M5 threaded insert\u003c\/li\u003e\n  \u003cli\u003eConstruction: Sealed AGM (Absorbent Glass Mat)\u003c\/li\u003e\n  \u003cli\u003eWeight: 9kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076041818\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCampervans and motorhomes requiring a compact, deep-cycle leisure battery.\u003c\/li\u003e\n  \u003cli\u003eNarrowboats and small marine vessels with daily charge and discharge cycles.\u003c\/li\u003e\n  \u003cli\u003eSmall off-grid solar systems with regular overnight discharge.\u003c\/li\u003e\n  \u003cli\u003eUPS and backup power installations where deep discharge events occur periodically.\u003c\/li\u003e\n  \u003cli\u003eMobile medical or telecoms equipment requiring a sealed, maintenance-free battery.\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 38Ah AGM Super Cycle Battery (M5 terminals)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThis battery operates at 12V and is suitable for installation by competent individuals familiar with DC electrical systems. For integration into solar PV systems or inverter-charger setups, installation by a qualified electrician or MCS-accredited installer is recommended. Ensure the charger profile is set to AGM or the specific Victron Super Cycle profile where available, as using an incorrect charge voltage can reduce cycle life. The battery must not be mounted in an inverted position. Ensure adequate ventilation in the installation space, as AGM batteries can vent gas under fault conditions.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":60227796173134,"sku":"BAT412038081","price":83.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_BAT412038081_-_12V-38Ah_AGM_Super_Cycle_Batt._M5.webp?v=1785164929","url":"https:\/\/voltaconsolar.com\/products\/victron-12v-38ah-agm-super-cycle-battery-m5","provider":"VoltaconSolar","version":"1.0","type":"link"}
