Frequently Asked Questions
- Do cylindrical lithium battery cells require visual inspection?
Yes, visual inspection is crucial for cylindrical lithium battery cells as the external appearance reflects the battery’s safety and performance. Our visual inspection typically includes checking the casing condition, connections, labels and markings, external insulation, leakage, and external cleanliness.
- Can cylindrical lithium batteries be charged with a power bank?
Yes, in addition to charging with a power bank, our lithium batteries support various charging methods such as chargers, laptops, and car chargers.
- What causes capacity degradation in cylindrical lithium batteries?
Capacity degradation (also known as capacity fade) in cylindrical lithium batteries refers to the gradual reduction of available capacity over time. This capacity loss is a normal part of battery usage but can be influenced by various factors such as the number of charge-discharge cycles, high temperatures, overcharging and over-discharging, storage time, and usage environment. To mitigate this, it is recommended to pay attention to usage and storage conditions, follow the specifications’ guidelines, and periodically replace aging batteries to prolong their lifespan and slow down capacity decline.
