MATERIALS FOR BATTERY TESTER


This is the battery tester we came up with to test the voltage and amperage of a battery. To do this you load the battery in it's size holder and turn on one incandescent bulb and read the voltage and amperage (one multi-meter is set to read voltage, the other is set to read amperage). You write down the reading and then turn on another bulb and document the readings. Finally you turn on the third incandescent bulb and document your final reading. This allows you to get preliminary data on a set of recharged batteries.
