3.7V Li-ion battery for digital devices
1. Why you should choose the lithium battery over alkaline battery?
High capacity & stable discharge voltage
Light weight & small size & high performance than any rechargeable battery
3.7V Li-ion battery for digital devices is a great option for today's high-end electronics as these cells typically have higher capacities than their alkaline counterparts. Although rechargeable batteries tend to cost a little more than standard alkaline batteries up front, these costs have reigned in because you won't need to replace rechargeable batteries nearly as often as alkaline battery.
