Using AGM (Absorbent Glass Mat) technology, the electrolyte is fully absorbed into the glass fiber, making this battery completely maintenance-free and free of any gas emissions during normal use. This design allows for safe installation in any onboard space without requiring complex ventilation.\u003c\/p\u003e\n\u003ch3\u003eStarting and cycling performance\u003c\/h3\u003e\n\u003cp\u003eEngineered to deliver very high discharge currents, this battery provides a cold cranking amps (CCA) rating of 1080 A (SAE) and 680 A (DIN). It is particularly well-suited for starting large marine engines or powering bow thrusters. Unlike traditional flooded lead-acid batteries, the glass fiber technology offers extremely low internal resistance. The use of thicker lead plates also ensures excellent durability for moderate cyclic use. For comparison, an AGM Mastervolt battery delivers starting power equivalent to a flooded lead-acid battery with nearly double the capacity, positioning this 225 Ah model as a superior alternative to market standards such as Victron Energy’s AGM ranges.\u003c\/p\u003e\n\u003ch3\u003eTechnical specifications and installation\u003c\/h3\u003e\n\u003cp\u003eWith dimensions of 522 x 240 x 224 mm and a weight of 63.5 kg, this group 8D battery fits perfectly in large service or starting battery banks. It accepts a maximum charging current of 63 A via IUoUo-characteristic chargers. The M8-type (type A) terminals are removable and compatible with all standard battery terminals. To optimize its service life, it is recommended to maintain a float voltage of 13.80 V and an absorption voltage of 14.25 V at 25°C, with temperature-compensated charging.","brand":"Mastervolt","offers":[{"title":"Default Title","offer_id":53723877048660,"sku":"62002250","price":525.31,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/main-square_e642a5c7-deb4-4510-9981-6bb8028d3fb1.jpg?v=1778053412","url":"https:\/\/skysat.fr\/en\/products\/mastervolt-agm-12v-225ah-group-8d-starting-battery","provider":"Skysat","version":"1.0","type":"link"}
