Battery Life

 

1. Background

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.

2. Objective
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 against time.
