1 Ampere-hour (Ah) is a unit of electric charge that represents the amount of energy a battery can deliver over one hour. Specifically, 1 Ah means that a battery can provide a current of 1 ampere for 1 hour. This measurement is crucial for determining battery capacity and understanding how long a battery will last under specific loads.
Understanding Ampere-Hours (Ah) in Battery Capacity
The concept of Ampere-hours (Ah) is fundamental in evaluating battery performance. This section will explore how Ah translates into practical applications, including its relevance to various battery types.
1. Definition and Calculation of Ampere-Hours
Ampere-hours quantify the total charge a battery can store and deliver. The formula to calculate Ah is:Ah=Current A ×Time h For example, if a battery discharges at a rate of 2 A for 3 hours, it provides:2A×3h=6Ah
| Current (A) | Time (h) | Total Ah |
|---|---|---|
| 1 | 1 | 1 |
| 2 | 3 | 6 |
| 5 | 2 | 10 |
2. Practical Implications of Ampere-Hours
Understanding Ah helps users select the right battery for their needs. For instance, a device requiring 5 A will deplete a 10 Ah battery in about 2 hours.
| Device Requirement | Battery Capacity (Ah) | Estimated Runtime |
|---|---|---|
| 5 A | 10 Ah | 2 hours |
| 3 A | 10 Ah | 3.33 hours |
| 1 A | 10 Ah | 10 hours |
3. Relation to Voltage and Watt-Hours
To convert Ampere-hours into watt-hours (Wh), which indicate total energy capacity, we use the formula:Wh=Ah×Voltage V For example, a 12V battery with a capacity of 10 Ah has:10Ah×12V=120Wh
| Battery Voltage (V) | Capacity (Ah) | Energy (Wh) |
|---|---|---|
| 12 | 10 | 120 |
| 24 | 5 | 120 |
| 48 | 2.5 | 120 |
