You can run a 100W device on a 100Ah battery for approximately 10 hours under ideal conditions. This calculation assumes the battery is fully charged and the voltage is stable. The actual runtime may vary based on factors like battery age, efficiency, and discharge rate.

Understanding Battery Capacity and Power Consumption

When managing energy needs, it’s essential to understand how battery capacity and power consumption interact. A 100Ah battery provides a certain amount of energy that can be used to power devices, while the wattage of those devices determines how long they can run.

1. Battery Capacity Explained

• Amp-Hour (Ah): This unit measures how much current a battery can deliver over a specific period. A 100Ah battery can theoretically provide 100 amps for one hour, or any equivalent combination (e.g., 10 amps for 10 hours).
• Voltage Consideration: To calculate total energy in watt-hours (Wh), you multiply the amp-hours by the voltage (V). For example, if the battery is 12V, then:

  Total Energy Wh =100 Ah×12 V=1200 Wh 

2. Power Consumption Calculation

To determine how long you can run a device, you need to consider its power consumption in watts (W):

• Power Formula: The formula to calculate runtime is:

  Runtime hours =Total Energy Wh / Power Consumption W  ​

Using the earlier example of a 100W device:

Runtime=1200 Wh100 W=12 hours 

However, this is under ideal conditions without accounting for efficiency losses.

3. Factors Affecting Runtime

Several factors can influence how long a battery will last when powering a device:

• Efficiency Losses: Real-world applications often experience efficiency losses due to heat and other factors, which may reduce actual runtime.
• Battery Age and Condition: Older batteries or those that have been poorly maintained may not deliver their rated capacity.
• Discharge Rate: Batteries have different discharge characteristics; drawing power at higher rates can reduce overall capacity.
