High-voltage lithium batteries use advanced technology and have a higher voltage than traditional lithium batteries, thus providing higher energy density. Their upper charging voltage can reach 4.35V or even 4.4V, which has a higher energy storage capacity than the 4.2V of traditional lithium batteries. This means that with the same capacity, our high-voltage lithium batteries can store more power and provide longer use time for your devices. As modern society has higher and higher requirements for the battery life of electronic products, our high-voltage lithium batteries will meet your higher requirements for standby time and use time.
