A 100Ah battery can run a 1000W load for approximately one hour if fully charged and assuming 100% efficiency. To calculate this, divide the battery capacity (in watt-hours) by the load: 100Ah × 12V = 1200Wh; then, 1200Wh ÷ 1000W = 1.2 hours. However, real-world conditions may reduce this time.
Understanding Battery Capacity and Load Calculation
When assessing how long a battery can power a specific load, such as a 1000W appliance, it is essential to understand the relationship between amp-hour (Ah) ratings, voltage, and power consumption. This understanding helps users make informed decisions about energy management in various applications.
1. Battery Capacity Explained
The capacity of a battery is typically measured in amp-hours (Ah), which indicates how much current a battery can supply over a specified period. For example, a 100Ah battery can theoretically provide:
- 100 amps for 1 hour
- 50 amps for 2 hours
- 25 amps for 4 hours
2. Power Consumption Calculation
To determine how long a battery will last when powering a specific load, we need to convert the amp-hour rating into watt-hours (Wh):
- Formula:
- Watt-hours = Amp-hours × Voltage
- For a common 12V battery, the calculation would be:
- 100Ah × 12V = 1200Wh
3. Running a 1000W Load
To find out how long the battery can run a 1000W load, use the following calculation:
- Formula:
- Runtime (hours) = Watt-hours ÷ Load (Watts)
- Runtime = 1200Wh ÷ 1000W = 1.2 hours
This means that under ideal conditions, a fully charged 100Ah battery at 12V can run a 1000W appliance for about 1.2 hours.
Battery Runtime Chart
| Battery Capacity | Voltage | Total Energy (Wh) | Load (W) | Runtime (Hours) |
|---|---|---|---|---|
| 100Ah | 12V | 1200 | 500 | 2.4 |
| 100Ah | 12V | 1200 | 750 | 1.6 |
| 100Ah | 12V | 1200 | 1000 | 1.2 |
| 100Ah | 12V | 1200 | 1500 | 0.8 |
