$begingroup$ You don''t measure current across a battery like that because an ammeter setting is effectively short circuiting the battery. In this case you were lucky it was only an AA cell. Had it been a car battery you would certainly have blown the fuse and/or destroyed the meter. Current is measured in series with a load.
A car battery''s power is measured in amp-hours (Ah) and watt-hours (Wh). Amp-hours show how much current the battery can provide in one hour. Watt-hours measure total energy output. You can convert between Ah and Wh using the formula: Wh = Ah × battery voltage. These measurements help evaluate battery capacity and performance.
For those who prefer a hands-on approach, a digital multimeter can measure battery capacity directly. The process involves: - Setting the multimeter: Switch the multimeter
- Measuring current: Set the multimeter to measure current (A) and connect it in series with the battery and a load. - Calculating capacity: By discharging the battery through a known load and measuring the time it takes to reach a specified voltage, users can calculate the capacity using the formula: Capacity (Ah) = Current (A) × Time (hours).
Fully charge the battery, discharge it at a constant current until it reaches its cut-off voltage, and calculate the capacity (mAh or Ah) based on the total discharge time.
