Thank you so much for this brilliant idea, can I know what value of resistor would be suitable for this experiment?Take a very well insulated (against heat loss I mean) container full of water and connect the battery to a resistor in the water. Then you measure the temperature of the water at the start and then watch the temperature rise. When it stops warming up, the difference in temperature and the specific heat of water will give you the total energy delivered to the water.
Can we know the voltage and amps-hours alleged to be in the battery?can I know what value of resistor would be suitable for this experiment?
The battery i'm using is an AA battery with voltage of 2V and 2600mAh. I'm planning to measure the maximum energy for 2 different kind of batteries which one of them would be a fully charge rechargeable battery and a newly bought non-rechargeable battery. The condition on the day of experiment wouldn't matterCan we know the voltage and amps-hours alleged to be in the battery?
For that matter, you can calculate energy by knowing the voltage and amp-hours in the battery.
The question remaining is, do you want to do the math while allowing for the decrease of voltage during discharge? Do you want to estimate for a new battery you might buy? Do you want to measure the reality of one battery in whatever condition it is in today?
