Get PriceEvery portable power station comes with a rated capacity, typically measured in watt-hours (Wh). This figure represents the total amount of energy stored in the battery.
Get PriceBattery capacity, typically measured in ampere-hours (Ah), indicates the total amount of energy a battery can store and deliver. It plays a crucial role in determining how long a battery can power a device before needing a recharge.
Every portable power station comes with a rated capacity, typically measured in watt-hours (Wh). This figure represents the total amount of energy stored in the battery. For example, an OUPES portable power station with a 1,000Wh capacity theoretically supplies 1,000 watts for one hour or 100 watts for ten hours.
A battery used to power a laptop computer may have an actual capacity of 5 Ah. This means that the battery can deliver 5 amperes of current for one hour, or 50 watt-hours of energy. The theoretical capacity of the same battery may be 10 Ah.
For instance, if a manufacturer states that a battery has a nominal capacity of 100Ah at a 10-hour discharge rate, this means it can deliver 10A continuously over that period. What factors affect the difference between actual and nominal capacity? Several factors can lead to discrepancies between actual and nominal capacities:
It plays a crucial role in determining how long a battery can power a device before needing a recharge. Knowing both actual and nominal capacities allows users to make informed decisions about battery performance, efficiency, and suitability for specific applications.
The theoretical capacity of the same battery may be 10 Ah. This means that the battery could theoretically deliver 10 amperes of current for one hour, or 100 watt-hours of energy. The rated capacity of the battery may be 8 Ah. This means that the battery is designed to deliver 8 amperes of current for one hour, or 80 watt-hours of energy.
