Batteries or electrical cells are made using a range of different
substances. There are zinc dry-cells, alkaline cells and lead-acid
accumulators. When you use them, they become exhausted at
different rates. Therefore choosing the right type of battery for
a job is very important.
In this investigation, we will measure the voltage of a cell
over a period of time and until it becomes exhausted. A voltage
sensor connected to a datalogger can help us take the readings
