Understanding 3.7 Volt Batteries
Before I made a purchase, I took the time to understand what a 3.7 Volt rechargeable battery is. These batteries are commonly lithium-ion or lithium-polymer types, and they are used in a variety of devices—from smartphones to drones. Knowing the voltage helps ensure compatibility with your devices.
