3. Example Calculation:
   • If you have a battery with a capacity of 2000mAh (or 2Ah) and it can safely discharge at 4A, the calculation would be:
     C Rating=4A2Ah=2CC Rating=2Ah4A​=2C
     This means the battery can deliver twice its capacity in one hour.

Interpreting the Results

• A 1C rating indicates that the battery can discharge its entire capacity in one hour.
• A 2C rating means it can discharge twice its capacity in one hour, or fully discharge in half an hour.
• Conversely, a 0.5C rating means it will take two hours to discharge fully.

Practical Considerations

• Ensure that units are consistent when performing calculations. If your battery’s capacity is in mAh, convert it to Ah by dividing by 1000.
• Check the manufacturer‘s specifications for maximum discharge rates, as exceeding these limits can lead to overheating and damage.

Conclusion

Calculating a battery’s C rating is straightforward and provides valuable insights into its performance capabilities. By understanding how to determine this rating, you can make informed decisions about which batteries are best suited for your specific needs, ensuring optimal performance and longevity.
