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
