Round Lithium Polymer Battery

The main difference between a 3.7V Lithium Polymer Battery and a 3.8V Lithium Polymer Battery lies in their nominal voltage, which represents the average voltage of the Lithium Polymer Battery during discharge.

  1. Nominal voltage: A 3.7V Lithium Polymer Battery has a nominal voltage of 3.7 volts, while a 3.8V Lithium Polymer Battery has a nominal voltage of 3.8 volts. This voltage difference might seem minor, but it can impact the performance and compatibility of the Lithium Polymer Battery with certain devices.
  2. Chemistry: The slight difference in nominal voltage can be a result of the specific battery chemistry used. For example, some lithium-ion batteries (Li-ion) have a nominal voltage of 3.6V or 3.7V, while lithium-ion polymer batteries (LiPo) can have a nominal voltage of 3.7V or 3.8V. Additionally, newer Li-ion chemistries, such as lithium nickel manganese cobalt oxide (NMC) and lithium nickel cobalt aluminum oxide (NCA), have slightly higher nominal voltages around 3.6V to 3.8V.
  3. Performance: The difference in voltage may affect the Lithium Polymer Battery’s performance, such as energy capacity and discharge rate. A higher voltage Lithium Polymer Battery can deliver more power, but it might also lead to increased heat generation and reduced lifespan if not properly managed.
  4. Compatibility: It is crucial to ensure that the Lithium Polymer Battery’s nominal voltage is compatible with the device it is intended for. Using a Lithium Polymer Battery with a different nominal voltage than specified by the device manufacturer can lead to poor performance or even damage to the device.

When choosing a Lithium Polymer Battery, always check the manufacturer’s recommendations for the required voltage and ensure the Lithium Polymer Battery’s voltage is compatible with the device.
