{"product_id":"renogy-12v-deep-cycle-agm-battery","title":"Renogy 12V Deep Cycle AGM Battery","description":"\u003cp class=\"product-lead\"\u003eThe Renogy 12V Deep Cycle AGM Battery is a sealed, maintenance-free lead-acid house battery for off-grid solar systems, RVs, overlanding rigs, vans, and cabins. Absorbent Glass Mat technology absorbs the electrolyte into a fiberglass mat separator, eliminating free-flowing acid and making the battery spill-proof with no routine maintenance required. The 200Ah variant delivers a rated capacity of 200Ah (20-hour rate to 10.5V) and a maximum discharge current of 2000A for 5 seconds. The 100Ah and 70Ah Start-Stop variants are also available; specifications for those sizes are not published for this listing.\u003c\/p\u003e\n\n\u003ch2\u003eSealed Design Means No Routine Maintenance\u003c\/h2\u003e\n\u003cp\u003eThe AGM battery's integrated sealed construction keeps the electrolyte locked in the fiberglass mat at all times. There is no water to top off, no acid to check, and no venting system to inspect on a schedule. For a solar beginner wiring a first off-grid system, or an overlander who wants a house battery that stays reliable between trips without active upkeep, that sealed design removes an entire category of recurring tasks.\u003c\/p\u003e\n\n\u003ch2\u003eWide Discharge Temperature Range\u003c\/h2\u003e\n\u003cp\u003eThe upgraded electrolyte formula in the Renogy AGM battery supports discharge from -4 to 140°F \/ -20 to 60°C. That range covers cold-weather camping and desert heat without requiring external temperature compensation hardware. The charge temperature range is narrower, at 32 to 122°F \/ 0 to 50°C, so charging below freezing is not supported; plan charging accordingly in winter conditions.\u003c\/p\u003e\n\n\u003ch2\u003eExpandable Bank Configuration\u003c\/h2\u003e\n\u003cp\u003eUp to four Renogy AGM batteries of the same voltage, capacity, and type can be connected in parallel to increase total amp-hour capacity. Series connections carry no stated limitation, making it straightforward to build a 24V or higher system. When connecting multiple batteries in any configuration, Renogy recommends using a battery balancer to extend service life. All batteries in a bank must be the same type (AGM), voltage, and capacity: mixing capacities or chemistries is not supported.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAGM sealed construction:\u003c\/strong\u003e spill-proof, maintenance-free, no

class=\"product-fit-yes\"\u003eThe Renogy 12V Deep Cycle AGM battery suits off-grid solar builds, RV house banks, overlanding and van electrical systems, and cabin backup power where a sealed, maintenance-free lead-acid battery is preferred over lithium. The wide discharge temperature range makes it workable in cold-weather and high-heat environments where charging infrastructure allows for the 32°F \/ 0°C minimum charge temperature.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThis battery does not support charging below 32°F \/ 0°C. It does not include a self-heating function. Mixing it in a bank with batteries of a different capacity, voltage, or chemistry is not supported. The 500A Battery Monitor is sold separately and is not included. Detailed specifications for the 100Ah and 70Ah Start-Stop variants are not published for this listing.\u003c\/p\u003e\n\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003ch3 class=\"product-faq-q\"\u003eWhat is an AGM battery and how does it differ from a flooded lead-acid battery?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eAn AGM (Absorbent Glass Mat) battery holds its electrolyte, a mixture of water and sulfuric acid, absorbed into a fiberglass mat separator rather than as free-flowing liquid. The Renogy 12V AGM battery's sealed design means no water topping, no acid spills, and no venting requirements that a traditional flooded battery would demand.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eHow deeply can the AGM battery be discharged without shortening its life?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eRenogy recommends not discharging the AGM battery below 50% state of charge to avoid reducing cycle life. The 200Ah variant is rated for 500 cycles at 50% depth of discharge. Discharging to 0% and recharging is possible but will shorten the total number of usable cycles.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eCan the AGM battery be charged in freezing temperatures?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Renogy AGM battery's discharge temperature range extends down to -4°F \/ -20°C, but the charge temperature range starts at 32°F \/ 0°C. Charging the battery below freezing is outside the supported range and will shorten its lifespan. The battery does not include a self-heating function.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eHow many AGM batteries can be connected together, and in what configurations?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eUp to four Renogy AGM batteries can be connected in parallel to increase total amp-hour capacity. Series connections carry no stated limitation, making 24V and higher systems possible. All batteries in a bank must share the same type (AGM), voltage, and capacity; connecting a 100Ah and a 200Ah battery together is not supported.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWhat charge controller battery type setting should be used with this battery?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eWhen configuring a charge controller to work with the Renogy AGM battery, select the SLD (sealed lead-acid) battery type setting.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWhat is the correct installation orientation for the AGM battery?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Renogy AGM battery should be installed upright. Side installation is permitted only when there is a specific reason that prevents upright placement. The battery must never be installed upside down. When mounting, leave 1.97 to 3.94 in (5 to 10 cm) of clearance above the top and at least 7.87 in (20 cm) of clearance on the busbar side.\u003c\/p\u003e","brand":"Renogy","offers":[{"title":"200Ah","offer_id":50656000999494,"sku":"RNG-BATT-AGM12-200-G3-US","price":395.99,"currency_code":"USD","in_stock":true},{"title":"100Ah","offer_id":50656001032262,"sku":"RNG-BATT-AGM12-100-G2-US","price":208.99,"currency_code":"USD","in_stock":true},{"title":"70Ah Start-Stop","offer_id":50656001065030,"sku":"RBT1270AGM-ST-G1-US","price":189.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0691\/2203\/1686\/files\/01_1__06904.1750404959.1280.1280.jpg?v=1792208361","url":"https:\/\/terrainvault.com\/products\/renogy-12v-deep-cycle-agm-battery","provider":"TerrainVault","version":"1.0","type":"link"}
