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, we have 5 factories in China to produce 18650 Li-ion batteries, and we have a sales office in Guangdong Province to accept customization.<\/div>\n
<\/div>\n
\n
Q: What is 3C discharge multiplier?<\/strong>
\nA: 3C discharge multiplier means that the battery can be discharged at 3 times the current of its capacity. For 2500mAh battery, 3C discharge current is 7.5A.<\/div>\n
<\/div>\n
Q: What is the maximum charging current for this battery?<\/strong>
\nA: It is recommended to use a maximum charging current of 1C, which is 2.5A, up to a maximum of 1.5C (3.75A) to ensure safety and prolong battery life.<\/div>\n
<\/div>\n
Q: What certifications do you have?<\/strong>
\nA: We have passed ISO certification, our products have passed UN38.3, CE, CB, ROHS, SGS and other mainstream tests in the industry, and are fully insured with product liability insurance.<\/div>\n
<\/div>\n
Q: How to store batteries?<\/strong>
\nA: Batteries should be stored in a cool, dry place, avoiding direct sunlight and high temperature environment. When stored for a long period of time, the battery should be kept at 40%-60% of its capacity to prevent loss of capacity due to over-discharge.<\/div>\n<\/div>\n
