It uses gel electrolyte technology, making it suitable for installations where battery orientation or ventilation is a constraint. Rated at 90Ah capacity at the C20 rate, it is a practical choice for professional installers specifying reliable energy storage in demanding environments.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e90Ah capacity rated at the C20 discharge rate, providing a consistent and predictable energy reserve for system sizing.\u003c\/li\u003e\n  \u003cli\u003eGel electrolyte construction eliminates free liquid acid, reducing the risk of spillage and allowing installation in confined or non-upright positions.\u003c\/li\u003e\n  \u003cli\u003eDeep cycle design supports repeated charge and discharge cycles, making it suitable for daily solar cycling rather than engine-start or float-only applications.\u003c\/li\u003e\n  \u003cli\u003eSealed, valve-regulated (VRLA) construction requires no topping up with distilled water and produces minimal off-gassing under normal operating conditions.\u003c\/li\u003e\n  \u003cli\u003e12V nominal voltage allows straightforward series and parallel configuration to build 24V or 48V battery banks.\u003c\/li\u003e\n  \u003cli\u003eManufactured by Victron Energy, with consistent quality control and compatibility with the full range of Victron charge controllers, inverter-chargers and battery monitors.\u003c\/li\u003e\n  \u003cli\u003eWeight of 22.5 kg reflects the dense lead-acid construction typical of this capacity class.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eGel batteries differ from standard flooded lead-acid batteries in that the electrolyte is immobilised in a silica gel matrix. This prevents stratification and reduces water loss, which extends service life in cyclic applications compared to conventional wet-cell batteries. The sealed construction also means the battery can be installed on its side if required, though upright is always preferred where space allows.\u003c\/p\u003e\n\n\u003cp\u003eAt 90Ah (C20), this battery is well suited to small-to-medium off-grid systems, solar storage banks, narrowboat and marine house battery installations, and backup power applications. When sizing a bank, note that gel batteries should not routinely be discharged below 50% depth of discharge (DoD) to preserve cycle life. Charge voltage settings must be configured correctly for gel chemistry: using AGM or flooded profiles will shorten battery life. Victron MPPT charge controllers and MultiPlus inverter-chargers include a dedicated gel charge profile.\u003c\/p\u003e\n\n\u003cp\u003eMultiple units can be connected in series to achieve 24V or 48V system voltages, or in parallel to increase capacity. When building a battery bank, use batteries of the same age, capacity and manufacturer to ensure balanced charging and discharging across the bank.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: BAT412800104\u003c\/li\u003e\n  \u003cli\u003eNominal voltage: 12V\u003c\/li\u003e\n  \u003cli\u003eCapacity: 90Ah at C20 rate\u003c\/li\u003e\n  \u003cli\u003eBattery type: Gel Deep Cycle, VRLA sealed\u003c\/li\u003e\n  \u003cli\u003eWeight: 22.5 kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076037200\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSolar off-grid energy storage in residential, agricultural and remote site installations.\u003c\/li\u003e\n  \u003cli\u003eMarine and narrowboat house battery banks where sealed construction is required.\u003c\/li\u003e\n  \u003cli\u003eMotorhome and caravan leisure battery systems with regular daily cycling.\u003c\/li\u003e\n  \u003cli\u003eUPS and backup power systems requiring a maintenance-free sealed battery.\u003c\/li\u003e\n  \u003cli\u003eTelecoms, security and remote monitoring installations with infrequent access for maintenance.\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 90Ah Gel Deep Cycle Battery\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eAlthough this is a sealed gel battery, installation in a well-ventilated enclosure is still recommended as a precaution. Ensure the charge source (MPPT controller, inverter-charger or mains charger) is set to the correct gel charge profile before connecting. Incorrect charge voltages, particularly overcharging, will permanently damage gel cells. For solar PV and off-grid system installations, connection by a qualified electrician or MCS-accredited installer is recommended. When building multi-battery banks, ensure all interconnecting cables are of equal length and cross-section to maintain balanced current distribution.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59856046719310,"sku":"BAT412800104","price":187.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_BAT412800104_-_12V-90Ah_Gel_Deep_Cycle_Batt..webp?v=1781101889","url":"https:\/\/voltaconsolar.com\/products\/victron-12v-90ah-gel-deep-cycle-battery","provider":"VoltaconSolar","version":"1.0","type":"link"}
