It is built for solar storage, marine, and off-grid systems where standard AGM batteries would degrade prematurely under regular deep-cycle use. The M5 threaded insert terminals provide a secure, vibration-resistant connection suitable for demanding installations.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eAGM Super Cycle technology tolerates deeper and more frequent discharge cycles than standard AGM batteries, extending service life in cyclic applications.\u003c\/li\u003e\n  \u003cli\u003e12V nominal voltage with 25Ah capacity, suitable for a wide range of small to medium off-grid and backup power systems.\u003c\/li\u003e\n  \u003cli\u003eM5 threaded insert terminals provide a firm, reliable connection and reduce the risk of terminal damage during installation or in high-vibration environments.\u003c\/li\u003e\n  \u003cli\u003eValve-regulated, sealed construction requires no maintenance and can be mounted in any orientation except inverted.\u003c\/li\u003e\n  \u003cli\u003eManufactured by Victron Energy, with consistent quality control and compatibility with the full Victron charging ecosystem including MPPT controllers and multi-stage chargers.\u003c\/li\u003e\n  \u003cli\u003eWeight of 6.45 kg makes it practical for portable and space-constrained installations.\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 AGM Super Cycle range addresses this by using a modified plate design and electrolyte formulation that allows discharge to lower state-of-charge levels without the same level of plate sulphation and degradation. This makes it a more practical choice for solar systems where the battery may be regularly drawn down overnight or during poor weather periods.\u003c\/p\u003e\n\n\u003cp\u003eThe 25Ah capacity at 12V gives a nominal energy storage of 300Wh. In practice, usable capacity depends on the depth of discharge limit set by the charge controller or inverter. Victron recommends pairing Super Cycle batteries with compatible Victron chargers to take full advantage of the battery's cycle life. The M5 threaded inserts are a notable practical detail: unlike standard bolt-on terminals, they accept M5 screws directly into the battery casing, which is more secure and less prone to stripping under repeated use.\u003c\/p\u003e\n\n\u003cp\u003eAs a sealed VRLA (valve-regulated lead-acid) battery, no topping up of electrolyte is required. The battery is suitable for indoor installation in ventilated enclosures. It is not designed for float-only standby applications where a lithium or gel chemistry would be more appropriate.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: BAT412025081\u003c\/li\u003e\n  \u003cli\u003eNominal Voltage: 12V\u003c\/li\u003e\n  \u003cli\u003eCapacity: 25Ah\u003c\/li\u003e\n  \u003cli\u003eTerminal Type: M5 threaded insert\u003c\/li\u003e\n  \u003cli\u003eChemistry: AGM (Absorbed Glass Mat), VRLA sealed\u003c\/li\u003e\n  \u003cli\u003eWeight: 6.45 kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076041801\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSmall off-grid solar systems with regular overnight discharge cycles.\u003c\/li\u003e\n  \u003cli\u003eMarine auxiliary power where vibration resistance and sealed construction are required.\u003c\/li\u003e\n  \u003cli\u003eMotorhome and caravan leisure battery banks.\u003c\/li\u003e\n  \u003cli\u003eUPS and backup power systems with frequent discharge events.\u003c\/li\u003e\n  \u003cli\u003ePortable power stations and mobile off-grid setups.\u003c\/li\u003e\n  \u003cli\u003eSupplementary storage in existing 12V battery banks.\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 25Ah 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 should be installed and connected by a competent electrician or qualified installer familiar with DC battery systems. Ensure the charging source (solar charge controller, mains charger, or alternator regulator) is set to the correct voltage profile for AGM batteries. Do not charge with a profile intended for gel or lithium chemistries. Install in a ventilated space and avoid inverting the battery during use. For systems forming part of a grid-connected installation, ensure all relevant wiring and protection devices comply with BS 7671 and any applicable DNO requirements.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59863661150542,"sku":"BAT412025081","price":43.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_BAT412025081_-_12V-25Ah_AGM_Super_Cycle_Batt._M5.webp?v=1781183023","url":"https:\/\/voltaconsolar.com\/products\/victron-12v-25ah-agm-super-cycle-battery-m5","provider":"VoltaconSolar","version":"1.0","type":"link"}
