12V 2000mah DC Rechargeable Li-Ion Battery

It's a 12V 2000mah DC Rechargeable Li-Ion Battery. A 12V 2000mAh DC rechargeable Li-Ion battery is a type of battery commonly used in various electronic devices. This battery has a nominal voltage of 12 volts. It means that it operates at this voltage level when fully charged. However, the actual voltage of a Li-Ion battery can vary depending on its charge level. When fully charged, the voltage can be slightly higher, typically around 12.6-12.8V, and it gradually drops as the battery discharges. The capacity of a battery refers to the amount of charge it can store and deliver. In this case, the battery has a capacity of 2000 milliampere-hours (mAh). It indicates that the battery can provide a current of 2000 milliamperes (mA) for one hour before being fully discharged. The higher the capacity, the longer the battery can power a device.
