Delivering a nominal capacity of 5700mAh at 3.6V nominal voltage with a maximum continuous discharge of 16.8A, the 58E offers high-capacity performance for flashlights, consumer electronics, and portable devices designed for the 21700 button top format. The integrated PCB protects against overcharge, over-discharge, over-current, and short circuit conditions. Standard charge current is 1.12A via CCCV method, with a maximum charge current of 5.6A. This protected button top cell is physically longer than a standard flat top unprotected 21700 battery — always verify dimensional compatibility with your device before purchase. Do not remove the protective wrap, as doing so may compromise the protection circuit.\u003c\/p\u003e \u003ch4\u003eApplications \/ Uses\u003c\/h4\u003e \u003cul\u003e \u003cli\u003eHigh-capacity flashlights and portable lighting systems designed for protected button top 21700 cells\u003c\/li\u003e \u003cli\u003eConsumer electronics and personal devices requiring button top 21700 format with built-in cell-level protection\u003c\/li\u003e \u003cli\u003ePortable power banks and single-cell devices benefiting from PCB overcharge and over-discharge protection\u003c\/li\u003e \u003cli\u003eMedical and industrial handheld devices requiring stable, protected lithium-ion power with high capacity\u003c\/li\u003e \u003cli\u003eReplacement cells for compatible button top 21700 devices where high capacity and protection are both required\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\u003eEVE Energy\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eModel:\u003c\/td\u003e\n\u003ctd\u003eINR21700-58E\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eBattery Type:\u003c\/td\u003e\n\u003ctd\u003e21700 Lithium-Ion\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eNominal Capacity:\u003c\/td\u003e\n\u003ctd\u003e5700mAh\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eMinimum Capacity:\u003c\/td\u003e\n\u003ctd\u003e5600mAh\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eNominal Voltage:\u003c\/td\u003e\n\u003ctd\u003e3.6V\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eMaximum Charge Voltage:\u003c\/td\u003e\n\u003ctd\u003e4.20V\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eDischarge Cut-off Voltage:\u003c\/td\u003e\n\u003ctd\u003e2.5V\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eMaximum Discharge Current:\u003c\/td\u003e\n\u003ctd\u003e16.8A\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eStandard Charge Current:\u003c\/td\u003e\n\u003ctd\u003e1.12A (CCCV)\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eMaximum Charge Current:\u003c\/td\u003e\n\u003ctd\u003e5.6A\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eProtected:\u003c\/td\u003e\n\u003ctd\u003eYes (PCB) — overcharge, over-discharge, over-current, short circuit\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eBattery Top:\u003c\/td\u003e\n\u003ctd\u003eButton Top\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-20°C to 60°C\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eApprox.
