Monitor and record the discharge time. Connect the battery in series with the multimeter to measure the current drawn by the load. Calculate the capacity by multiplying the discharge current (in amps) by the time it took for the battery to reach its cutoff voltage.
We use a battery holder for our battery because the battery holder gives us two leads (one negative and one positive) so that we can connect it to the DC power supply via 2 alligator clips. Without the battery holder and its leads, it would be very difficult to allow for connection with the battery cell.
Without the battery holder and its leads, it would be very difficult to allow for connection with the battery cell. So if we are charging a single 'AA' battery, we need a single 'AA' battery holder. If we are charging 2 'AA' batteries, we need a double 'AA' battery holder, and so on.
To charge the battery, the buck converter is enabled while the first-stage voltage Op Amps and current-sense INA are used to measure battery voltage and charging current of the battery cell or battery pack.
The circuit design for this charger is a basic Arduino controlled power supply. The circuit power supply, we will be using an AC/DC power supply. Most USB ports would not be appropriate for this project because of the current limitations. The 5V source charges the battery through a 10 ohm power resistor and a power MOSFET.
There are two ways to check if the correct current is being output. One is to change the DC Power Supply to the "Amp" Setting. It should display the amount of amperes being output. The next is to use a multimeter to read the amps output. Make sure that it's the current the battery was designed to be charged at.
