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: What is 1C discharge ratio?<\/strong>
\nA: 1C discharge ratio means that the battery can be discharged at a current that is one times its capacity. For a 2500mAh battery, 1C means the maximum discharge current is 2.5A.<\/div>\n
<\/div>\n
\n
Q: Is the battery suitable for parallel or series connection?<\/strong>
\nA: Yes, batteries can be connected in series to increase voltage or in parallel to increase capacity. However, a battery management system is required when connecting batteries in series and parallel to ensure the balance and safety of the battery pack.<\/div>\n
<\/div>\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. insured with product liability insurance.<\/div>\n
<\/div>\n
Q: How to dispose and recycle the batteries?<\/strong>
\nA: Please dispose of your lithium batteries according to local regulations and avoid throwing them away. Most places have specialized battery recycling stations to ensure safe disposal.<\/div>\n
<\/div>\n
Q: How does battery capacity affect when connected in parallel?<\/strong>
\nA: When connected in parallel, battery capacity will be stacked. When two 2500mAh batteries are used in parallel, the total system capacity is 5000mAh.<\/div>\n<\/div>\n
