In terms of charging cylindrical lithium-ion batteries, the maximum charging current of many chargers can reach 3A, 4A or even higher. This can fully charge a battery as soon as possible, greatly reducing the waiting time. However, some people also feedback that they don't like fast charging. They think that the 18650 charging current above 1A is too high and will affect the battery life. Therefore, when they buy lithium-ion battery chargers, they tend to choose those supporting manually adjust the charging current, and use small charging current. So, will fast charging damage the li-ion battery life?

TC-CC-CV charging method is a three-stage process of charging lithium-ion batteries. It is first originated from XTAR, the top-brand Li-ion battery charger manufacturer in China. This method prolongs Li-ion battery life and improves capacity utilization by charging with the right current at each stage and accurately cut-off charging at the right time.

After the 26650 battery, the bigger size 26800 appeared in the field of flashlights. The 26800 battery has a larger capacity and current. The…
