Amps to Amp Hours Calculator
A simple guide to understand battery capacity and convert between Amps (A) and Amp Hours (Ah).
What is Amp Hours (Ah)?
Think of Amp Hours like your battery’s gas tank – it tells you how much energy your battery can store. Just as gallons tell you how much fuel your car can hold, Amp Hours tell you how much electrical charge your battery can hold.
Simple Example: A 100Ah battery can power:
- A 1-amp device for 100 hours
- A 10-amp device for 10 hours
Converting Amps to Amp Hours
Here’s the simple formula you need:
- Amps = How much power your device uses
- Hours = How long you’ll use the device
- Amp Hours = The battery capacity you need
Comparing Different Batteries
When comparing batteries with different voltages, we use Watt Hours:
Quick Comparison
12V Battery with 100Ah
100Ah ร 12V = 1200Wh
24V Battery with 50Ah
50Ah ร 24V = 1200Wh
Both batteries store the same energy, just in different ways!
Real-Life Examples
Sizing a Battery for Your Device
Let’s say your device needs:
- 2 amps of power
- Runs for 5 hours
You’ll need a battery with: 10 Amp Hours
2 Amps ร 5 Hours = 10 Amp Hours
