Delivering a standard discharge capacity of ≥5330mAh at a nominal voltage of 3.64V, the 58E achieves a typical energy output of 20.0Wh per cell — among the highest available in the 21700 format. Its maximum continuous discharge rating of 2C \/ 10.7A makes it well suited to applications with moderate, sustained current requirements, where energy density takes priority over peak discharge capability. An initial AC impedance of ≤15mΩ supports efficient energy delivery with minimal resistive losses, and a rated cycle life of ≥4136mAh after 500 cycles under standard charge and discharge conditions ensures dependable performance over extended service. The 58E is an unprotected cell intended for integration into professionally engineered battery pack assemblies with appropriate protection circuitry and spot-welded interconnects — direct soldering to the cell is not recommended.\u003c\/p\u003e \u003ch4\u003eApplications \/ Uses\u003c\/h4\u003e \u003cul\u003e \u003cli\u003eElectric vehicles and e-bikes prioritizing maximum range and energy density per cell\u003c\/li\u003e \u003cli\u003eProfessional battery pack manufacturing for energy storage and long-runtime systems\u003c\/li\u003e \u003cli\u003ePortable power stations and backup energy systems requiring high per-cell capacity\u003c\/li\u003e \u003cli\u003eMedical devices and industrial equipment where consistent, controlled discharge is essential\u003c\/li\u003e \u003cli\u003eLighting systems, robotics, and electronics applications demanding high energy density and cycle reliability\u003c\/li\u003e \u003c\/ul\u003e \u003ch4\u003eSpecifications\u003c\/h4\u003e \u003cdiv class=\"table-wrapper\"\u003e \u003ctable\u003e \u003ctbody\u003e \u003ctr\u003e\n\u003ctd\u003eBrand:\u003c\/td\u003e\n\u003ctd\u003eSamsung SDI\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eModel:\u003c\/td\u003e\n\u003ctd\u003e58E (CC5493F101)\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eBattery Type:\u003c\/td\u003e\n\u003ctd\u003e21700 Lithium-Ion (INR)\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eStandard Discharge Capacity:\u003c\/td\u003e\n\u003ctd\u003e≥5330mAh (0.2C to 2.5V)\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eRated Discharge Capacity:\u003c\/td\u003e\n\u003ctd\u003e≥5170mAh (1C to 2.5V)\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eTypical Energy:\u003c\/td\u003e\n\u003ctd\u003e20.0Wh\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eNominal Voltage:\u003c\/td\u003e\n\u003ctd\u003e3.64V\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eFull Charge Voltage:\u003c\/td\u003e\n\u003ctd\u003e4.20V\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eDischarge Cutoff Voltage:\u003c\/td\u003e\n\u003ctd\u003e2.5V\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eStandard Charge Current:\u003c\/td\u003e\n\u003ctd\u003e0.5C \/ 2665mA\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eMaximum Charge Current:\u003c\/td\u003e\n\u003ctd\u003e1C \/ 5330mA\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eStandard Charge Time:\u003c\/td\u003e\n\u003ctd\u003e~4 hours\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eCharge Method:\u003c\/td\u003e\n\u003ctd\u003eCC-CV\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eMax Continuous Discharge:\u003c\/td\u003e\n\u003ctd\u003e2C \/ 10.7A\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eInitial AC Impedance:\u003c\/td\u003e\n\u003ctd\u003e≤15mΩ (AC 1kHz)\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eCycle Life:\u003c\/td\u003e\n\u003ctd\u003e≥4136mAh after 500 cycles\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eCharge Temperature:\u003c\/td\u003e\n\u003ctd\u003e0°C to 45°C\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eDischarge Temperature:\u003c\/td\u003e\n\u003ctd\u003e-10°C to 60°C\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eStorage Temperature:\u003c\/td\u003e\n\u003ctd\u003eUp to 1 year at -20°C to 23°C\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eBattery Top:\u003c\/td\u003e\n\u003ctd\u003eFlat Top\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eProtected:\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eDiameter:\u003c\/td\u003e\n\u003ctd\u003e21.78mm (Max)\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eHeight:\u003c\/td\u003e\n\u003ctd\u003e71.00mm (Max)\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eWeight:\u003c\/td\u003e\n\u003ctd\u003e74g (Max)\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eRechargeable:\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003c\/div\u003e","brand":"Samsung SDI","offers":[{"title":"Default Title","offer_id":67646855774518,"sku":"SAMSUNG-58E","price":6.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0721\/2761\/1190\/files\/SAMSUNG-58E.jpg?v=1791309105","url":"https:\/\/18650battery.com\/products\/samsung-58e-21700-5330mah-10-7a-battery","provider":"18650Battery","version":"1.0","type":"link"}
