SUMMARY

The maximum current that can be safely drawn from AA batteries varies based on the specific battery type, with some designed for higher power drains. To maximize amps from two AA batteries, connecting them in parallel is recommended, as this configuration increases current capacity while maintaining voltage. The discharge time is influenced by the battery's construction and is typically rated in amp-hours, which can be converted to watt-hours using voltage. Applying Ohm's Law and considering both external and internal resistance is essential for accurate calculations.

PREREQUISITES
  • Understanding of basic circuit theory
  • Familiarity with Ohm's Law
  • Knowledge of battery specifications, including amp-hour ratings
  • Ability to calculate power dissipation in resistive circuits
NEXT STEPS
  • Research the specifications of different AA battery types for current ratings
  • Learn about internal resistance and its impact on battery performance
  • Study how to calculate discharge time using amp-hours and watt-hours
  • Explore advanced circuit design techniques for optimizing battery usage
USEFUL FOR

Electronics enthusiasts, hobbyists working on battery-powered projects, and engineers seeking to optimize power consumption in devices.

What's the maximum amps that can i get from an aa battery without damaging it and how fast that should happen? Also if i had 2 aa batteries and i want to get maximum amps, how it is better to connect them (series or paralel) and how much does it take them to discharge? (sorry for my poor english grammar). Thank you!

The maximum current you can safely draw depends on the battery - some batteries are engineered to cope with a higher power drain than others. Try reading the label on the battery for useage limitations.

You should be able to use some basic circuit theory to work out the answers to the restof your questions.
Put your battery combination in a simple circuit with a resistance R. Don't forget the internal resistance r for each battery.

Use Ohms' Law and the definition of power.
Compare the differente cases.

The time to drain the battery depends on how the battery is built too - batteries are usually rated in amp-hours, knowing the voltage you can turn that into watt-hours and compare with the power dissipated in the different resistances.
