The name simply describes its physical dimensions: it is roughly 18mm in diameter and 65mm in length (the \"0\" indicates a cylindrical shape). They are known for packing a high energy density into a compact size and are the standard power source for everything from laptops and LED flashlights to DIY battery packs and electric vehicles.\u003c\/p\u003e\n\u003cp data-path-to-node=\"1\"\u003eHere are the standard technical specifications for most 18650 cells:\u003c\/p\u003e\n\u003cul data-path-to-node=\"2\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"2,0,0\"\u003eNominal Voltage: Usually 3.6V or 3.7V (this is the average voltage during a typical discharge).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"2,1,0\"\u003eMaximum Charge Voltage: 4.2V (the cell's voltage when it is 100% fully charged).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"2,2,0\"\u003eDischarge Cut-off Voltage: Typically 2.5V to 3.0V.

Any 18650 battery claiming a capacity significantly higher than 3600mAh (such as 5000mAh) is almost certainly counterfeit or overstating its capabilities.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"2,4,0\"\u003eContinuous Discharge Current (CDR): This measures how much current the battery can safely supply without overheating. High-capacity cells may only offer 5A to 8A, while specialized \"high-drain\" cells can deliver 20A to 30A for power tools or demanding devices.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"2,5,0\"\u003eCycle Life: Quality cells are usually rated for 300 to 500 full charge cycles before their capacity permanently drops to about 80% of its original rating.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"scientifickart","offers":[{"title":"1200 mAh","offer_id":51359768117554,"sku":"OM-31042","price":36.0,"currency_code":"INR","in_stock":true},{"title":"2000 mAh","offer_id":51359768150322,"sku":"OM-31042","price":45.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0951\/6561\/2338\/files\/ChatGPTImageJun24_2026_02_16_01PM.png?v=1782290789","url":"https:\/\/scientifickart.com\/products\/li-ion-battery-1200mah-3-7v-18650-rechargeable-battery","provider":"scientifickart","version":"1.0","type":"link"}
