Product Features<\/b><\/h2>\n

Sufficient Capacity<\/strong><\/h3>\n
Our INR18650 lithium batteries are manufactured with a design capacity that is typically greater\u00a0than the nominal\u00a0capacity to ensure thatevery cell delivered to our customers is greater than the\u00a0nominal capacity.<\/div>\n

High Cycle<\/strong><\/h3>\n
All models are guaranteed to maintain more than 80% of their capacity when cycling cycles reach\u00a0300 weeks, and some\u00a0models can achieve 500 weeks.<\/div>\n
\n
ps: The above data is actually derived from the testing data of actual batches.<\/div>\n
\n

Low Internal Resistance<\/strong><\/h3>\n
Different models of batteries have slightly different internal resistance, we ship batteries with\u00a0internal resistance\u00a0between 13-18M\u03a9.\u00a0If you have special requirements, we can customize the\u00a0production according to customer needs.<\/div>\n
\n

Ultra-Low Self-Discharge<\/strong><\/h3>\n
Adopting low self-discharge technology, strong power preservation, minimizing the natural loss of\u00a0power. The battery\u00a0can be used\u00a0for a long time.<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

FAQs<\/b><\/h2>\n
Q: Are you a trader or a manufacturer?<\/strong>
\nA: We are a manufacturer with 5 factories producing 18650 Li-ion batteries in China, sales office in Guangdong Province, accept custom.<\/div>\n
<\/div>\n
\n
Q: What kind of certification do you have?<\/strong>
\nA: The company has passed ISO certification and its products have passed UN38.3, CE, CB, ROHS, SGS and other mainstream industry tests, and is fully insured with product liability insurance.<\/div>\n
<\/div>\n
Q: What is 3C discharge ratio?<\/strong>
\nA: 3C discharge multiplier means that the battery can be discharged at 3 times the current of its rated capacity. For a 2000mAh battery, 3C means that the battery supports a continuous discharge current of up to 6A, which is suitable for devices that require medium discharge power.<\/div>\n
<\/div>\n
Q: What devices is this battery suitable for?<\/strong>
\nA: This 3.7V 2000mAh Li-ion battery is suitable for devices that require medium current output, such as power tools, small drones, robots, electronic devices, and flashlights, etc. It is especially good for applications that require higher power support.<\/div>\n
<\/div>\n
Q: What is the recommended charging current for this battery?<\/strong>
\nA: A charging current of 0.5C to 1C is recommended, with about 1A recommended. Typically, a full charge takes 2-3 hours, depending on the specifications of the charger.<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
