batterikapasiteten

Batterikapasitet, often translated as battery capacity, refers to the amount of electrical charge a battery can store and deliver. It is typically measured in ampere-hours (Ah) or milliampere-hours (mAh), where one ampere-hour represents the amount of charge transferred by a constant current of one ampere flowing for one hour. A higher ampere-hour rating indicates that a battery can supply a given current for a longer period, or a higher current for a shorter period. For example, a 10Ah battery can theoretically supply 1A for 10 hours, or 2A for 5 hours, assuming ideal conditions. The actual usable capacity can be affected by factors such as temperature, discharge rate, and the battery's age and condition. In consumer electronics, capacity is often expressed in watt-hours (Wh), which takes into account both the capacity in ampere-hours and the battery's nominal voltage. Watt-hours represent the total energy the battery can deliver. Understanding batterikapasitet is crucial for estimating how long a device will run on a single charge and for selecting appropriate batteries for specific applications.
