Product Features
Sufficient Capacity
Our INR18650 lithium batteries are manufactured with a design capacity that is typically greater than the nominal capacity to ensure thatevery cell delivered to our customers is greater than the nominal capacity.
High Cycle
All models are guaranteed to maintain more than 80% of their capacity when cycling cycles reach 300 weeks, and some models can achieve 500 weeks.
ps: The above data is actually derived from the testing data of actual batches.
Low Internal Resistance
Different models of batteries have slightly different internal resistance, we ship batteries with internal resistance between 13-18MΩ. If you have special requirements, we can customize the production according to customer needs.
Ultra-Low Self-Discharge
Adopting low self-discharge technology, strong power preservation, minimizing the natural loss of power. The battery can be used for a long time.

Q: How to store batteries?
A: 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.
