SUMMARY

The energy stored in a battery can be calculated using the formula E = V * AH * 3600, where E represents energy in Joules, V is the battery voltage, and AH is the battery capacity in amp-hours. This calculation is essential for understanding battery performance and efficiency. The factor of 3600 converts amp-hours to Joules by accounting for the number of seconds in an hour. This method is straightforward and applicable to various battery types.

PREREQUISITES
  • Understanding of basic electrical concepts, including voltage and current.
  • Familiarity with battery specifications, specifically amp-hours (AH).
  • Knowledge of unit conversions, particularly between hours and seconds.
  • Basic mathematical skills for applying the energy formula.
NEXT STEPS
  • Research the characteristics of different battery types and their voltage ratings.
  • Learn about battery capacity measurement and how to interpret amp-hour ratings.
  • Explore energy efficiency in battery systems and how to optimize performance.
  • Investigate advanced battery technologies and their energy storage capabilities.
USEFUL FOR

Engineers, electricians, and anyone involved in battery technology or energy storage solutions will benefit from this discussion.

If you know the battery voltage V, and the battery capacity AH in amp-hours, the energy stored by the battery in Joules is just E = V*AH*3600, where the 3600 is the number of seconds in an hour.May 18, 2014

Welcome to the PF, Saleem. :smile:

We hope you enjoy the forums!
 
Most likely this can only be answered by an "old timer". I am making measurements on an uA709 op amp (metal can). I would like to calculate the frequency rolloff curves (I can measure them). I assume the compensation is via the miller effect. To do the calculations I would need to know the gain of the transistors and the effective resistance seen at the compensation terminals, not including the values I put there. Anyone know those values?
