It is a particularly convenient spare for customers using powerful compatible Fenix lights away from home, because the battery can be recharged directly without a separate battery charger.\u003c\/p\u003e\u003ch3\u003eCharge Directly By USB-C\u003c\/h3\u003e\u003cp\u003eA suitable USB-C cable allows the battery to charge independently of the light. The built-in indicator shows red while charging and blue when charging is complete, making it easy to prepare a spare for the next shift, journey or outdoor trip.\u003c\/p\u003e\u003ch3\u003eHigh Capacity With Built-In Protection\u003c\/h3\u003e\u003cp\u003eThe 5000mAh capacity supports extended use in compatible high-output lighting. Protection circuitry helps guard against overcharging, over-discharging, short circuits and overheating, while pressure-relief vents add another layer of safety.\u003c\/p\u003e\u003ch3\u003eCheck Compatibility Before Ordering\u003c\/h3\u003e\u003cp\u003eThis battery is designed only for compatible 21700-powered products. It cannot be used in 18650 lights, and its integrated USB-C port can make it unsuitable for some older chargers or tightly sized battery compartments. It is not compatible with products requiring the ARB-L21-6000 specification.\u003c\/p\u003e\u003ch3\u003eFeatures \u0026amp; Specifications\u003c\/h3\u003e\u003ctable style=\"width: 100%; border-collapse: collapse;\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth style=\"padding: 8px; border: 1px solid #dddddd; text-align: left; width: 35%;\"\u003eBattery type\u003c\/th\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid #dddddd; text-align: left;\"\u003eProtected button-top 21700 Li-ion battery with integrated USB-C charging.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding: 8px; border: 1px solid #dddddd; text-align: left; width: 35%;\"\u003eCapacity\u003c\/th\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid #dddddd; text-align: left;\"\u003e5000mAh.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding: 8px; border: 1px solid #dddddd; text-align: left; width: 35%;\"\u003eNominal voltage\u003c\/th\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid #dddddd; text-align: left;\"\u003e3.6V.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding: 8px; border: 1px solid #dddddd; text-align: left; width: 35%;\"\u003eRecommended external charging current\u003c\/th\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid #dddddd; text-align: left;\"\u003e1A.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding: 8px; border: 1px solid #dddddd; text-align: left; width: 35%;\"\u003eMaximum external charging current\u003c\/th\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid #dddddd; text-align: left;\"\u003e5A.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding: 8px; border: 1px solid #dddddd; text-align: left; width: 35%;\"\u003eCharging indicator\u003c\/th\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid #dddddd; text-align: left;\"\u003eRed while charging and blue when fully charged.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding: 8px; border: 1px solid #dddddd; text-align: left; width: 35%;\"\u003eExpected service life\u003c\/th\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid #dddddd; text-align: left;\"\u003eUp to 500 charging cycles.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding: 8px; border: 1px solid #dddddd; text-align: left; width: 35%;\"\u003eDimensions\u003c\/th\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid #dddddd; text-align: left;\"\u003eApproximately 76 × 21.5mm.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding: 8px; border: 1px solid #dddddd; text-align: left; width: 35%;\"\u003eWeight\u003c\/th\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid #dddddd; text-align: left;\"\u003eApproximately 72.5g.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eWhat’s Included?\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eOne Fenix ARB-L21-5000U rechargeable battery.\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003ePlease note:\u003c\/strong\u003e A USB-C charging cable is not included.\u003c\/p\u003e\u003cp\u003eThe rechargeable battery is covered by a 1-year UK warranty.\u003c\/p\u003e\u003cp\u003eRight Light supplies genuine Fenix lighting products, batteries and accessories.\u003c\/p\u003e","brand":"Fenix","offers":[{"title":"Default Title","offer_id":49018660454649,"sku":"ARB-L21-5000U","price":22.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0412\/1342\/7861\/files\/avTaDaw5fW8G5HSI3zrx7UZ1YUnrFhOirZvqXJQy.jpg?v=1788692959","url":"https:\/\/www.right-light.co.uk\/products\/fenix-arb-l21-5000u-usb-21700-rechargeable-battery-5000mah","provider":"Right Light","version":"1.0","type":"link"}
