Starting from the authentic LG Chem MJ1 flat top cell, a third-party manufacturer adds a button top terminal and PCB protection circuit covering overcharge, over-discharge, over-current, and short circuit — giving you cell-level protection without needing an external BMS. At 3500mAh and 10A continuous discharge, it handles everything from high-performance flashlights to single-cell electronics with plenty of capacity to spare. One thing to know before you order: the added button top and PCB make this cell physically longer than a standard flat top unprotected 18650 — measure your device's battery compartment and confirm the fit first.\u003c\/p\u003e \u003ch4\u003eApplications \/ Uses\u003c\/h4\u003e \u003cul\u003e \u003cli\u003eHigh-capacity flashlights and portable lighting designed for protected button top 18650 cells\u003c\/li\u003e \u003cli\u003eConsumer electronics, personal devices, and everyday carry gear requiring button top 18650 format\u003c\/li\u003e \u003cli\u003ePortable power banks and single-cell devices where built-in PCB protection adds essential safety\u003c\/li\u003e \u003cli\u003eMedical and industrial handheld equipment requiring long-runtime protected lithium-ion power\u003c\/li\u003e \u003cli\u003eButton top 18650 replacements where 3500mAh capacity and protection circuit are both a requirement\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\u003eLG Chem\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eModel:\u003c\/td\u003e\n\u003ctd\u003eMJ1\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eBattery Type:\u003c\/td\u003e\n\u003ctd\u003e18650 Lithium-Ion\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eNominal Capacity:\u003c\/td\u003e\n\u003ctd\u003e3500mAh\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 Voltage:\u003c\/td\u003e\n\u003ctd\u003e4.2V\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eMax Continuous Discharge:\u003c\/td\u003e\n\u003ctd\u003e10A\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\u003eApprox.
