KP 403040 1000mAh 3.7V Lipo Rechargeable Battery

It's a 3.7V 1000mAh  Lipo Rechargeable Battery. A 3.7V 1000mAh lithium polymer (LiPo) rechargeable battery is a type of battery commonly used in various electronic devices. The battery has a nominal voltage of 3.7 volts. This is the average voltage output of the battery during its discharge cycle. It's important to note that the actual voltage can vary slightly depending on the charge level of the battery. The battery has a capacity of 1000mAh, which stands for milliampere-hours. This capacity indicates the amount of charge the battery can hold and deliver over a specific period. In this case, the battery can theoretically supply a current of 1000 milliamperes (or 1 amperes) for one hour before it's fully discharged. Lithium polymer batteries are a type of rechargeable battery that uses a polymer electrolyte instead of a liquid electrolyte. This design allows for flexibility in shape and size, making them suitable for slim and compact devices. They are commonly used in smartphones, tablets, drones, portable electronic devices, and other consumer electronics.
