How Is Battery Capacity Measured in Ampere-Hours (Ah)?
Battery capacity is measured in ampere-hours (Ah). This unit indicates the amount of electric charge a battery can deliver over a specific period. One ampere-hour equals one ampere of current flowing for one hour. To understand this measurement, consider that a higher Ah rating means a battery can supply more current for a longer time.
For example, a battery with a capacity of 17.5 Ah can provide a continuous current of 17.5 amperes for one hour before it is fully discharged. Alternatively, it could supply a lower current for a more extended period. This measurement is crucial for determining the performance and range of devices powered by batteries, such as electric bikes. Understanding battery capacity in ampere-hours helps users gauge how long their devices will run before needing a recharge.
Why Is 17.5Ah Considered a Common Capacity for Electric Bikes?
17.5Ah is considered a common capacity for electric bikes because it strikes a balance between weight, size, and the desired performance range. This capacity provides sufficient energy storage for daily commuting and recreational riding without significantly increasing the bike’s weight.
The Electric Bike Company defines amp-hour (Ah) as the measure of how much electricity a battery can store and deliver over time. One amp-hour indicates that a battery can deliver one amp of current for one hour. This definition highlights the importance of capacity in determining an electric bike’s range and performance.
Several underlying causes contribute to 17.5Ah being a popular choice for electric bike batteries. First, this capacity offers a practical range of approximately 30 to 50 miles, depending on various factors like terrain and rider weight.
