The plates are thicker and the active material is formulated to withstand the mechanical stress of repeated deep discharge cycles. This matters in solar and off-grid applications where the battery may be discharged to 50% or below on a daily basis. Using a standby-rated battery in a cyclic role significantly shortens service life; this battery is built specifically for that duty.\u003c\/p\u003e\n\n\u003cp\u003eThe C20 rating means the 165Ah capacity is measured over a 20-hour discharge period. At higher discharge rates the available capacity will be lower, which is standard behaviour for lead-acid chemistry. Charge voltage settings should be configured according to Victron's published AGM profile: typically 14.4V absorption and 13.8V float for a 12V battery. Incorrect charge voltages are the most common cause of premature battery failure, so verifying charger settings before commissioning is essential.\u003c\/p\u003e\n\n\u003cp\u003eAt 44.5 kg, handling and positioning this battery requires care. Two-person lifting or appropriate mechanical handling equipment is recommended during installation. The sealed AGM construction means the battery can be mounted on its side if required, though upright orientation is standard practice.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: BAT412151084\u003c\/li\u003e\n  \u003cli\u003eNominal voltage: 12V\u003c\/li\u003e\n  \u003cli\u003eCapacity (C20): 165Ah\u003c\/li\u003e\n  \u003cli\u003eChemistry: AGM (Absorbed Glass Mat)\u003c\/li\u003e\n  \u003cli\u003eType: Deep Cycle\u003c\/li\u003e\n  \u003cli\u003eWeight: 44.5 kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076037033\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSolar energy storage in off-grid residential and commercial installations.\u003c\/li\u003e\n  \u003cli\u003eBattery banks for MultiPlus or Quattro inverter\/charger systems.\u003c\/li\u003e\n  \u003cli\u003eMarine and leisure applications requiring deep cycle capability.\u003c\/li\u003e\n  \u003cli\u003eBackup power systems with regular discharge and recharge cycles.\u003c\/li\u003e\n  \u003cli\u003eMobile and vehicle-based power systems where a sealed, spill-proof battery is required.\u003c\/li\u003e\n  \u003cli\u003eTelecoms and remote monitoring installations with solar charging.\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 165Ah AGM Deep Cycle Battery\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 by a qualified electrician or accredited solar installer. Ensure the charge source (MPPT controller, inverter\/charger or mains charger) is programmed with the correct AGM deep cycle charge profile before connecting. When building a battery bank, use cables of equal length and cross-section to all terminals to ensure balanced charging and discharging across units. Batteries should be installed in a ventilated location even though AGM construction produces minimal gassing under normal conditions. Do not install in direct contact with heat sources or in environments subject to freezing temperatures, as both conditions reduce capacity and service life.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59856046424398,"sku":"BAT412151084","price":342.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_BAT412151084_-_12V-165Ah_AGM_Deep_Cycle_Batt..webp?v=1781101880","url":"https:\/\/voltaconsolar.com\/products\/victron-12v-165ah-agm-deep-cycle-battery","provider":"VoltaconSolar","version":"1.0","type":"link"}
