Although many tests can be performed to assess the condition of the batteries such as ohmic testing, specific gravity, state of charge etc., only the capacity test, commonly referred to as the discharge or load test, can measure the true capacity of the battery system and in turn determine the state of heath of the batteries.
With a microcontroller, like the good old AVR chip, we can make a rechargeable battery tester that does the work for us. My tester puts AA batteries through a discharge test and reports the capacity in milliamp-hours (mAh) so you can compare battery capacity. The tester can test multiple cells individually, and display the results on an LCD.
To test the condition of a rechargeable battery, you will need the following tools: Multimeter – A multimeter helps measure voltage, current, and resistance. Battery tester/analyzer – A dedicated battery tester can provide more accurate readings. Battery charger – A charger is required for certain testing methods.
By measuring the voltage across the battery, its remaining capacity can be preliminarily estimated. The constant current discharge method is a more accurate battery capacity test method. Connect the battery to a certain load and discharge it at a constant current until the battery voltage drops to the predetermined cut-off voltage.
A discharge test determines the battery’s ability to sustain a steady output under load. Connect the battery to a discharge resistor and measure the voltage over time. A healthy battery should maintain a stable voltage throughout the test. Measuring the internal resistance provides insight into the battery’s overall health.
A performance test is defined as “a constant-current or constant-power capacity test made on a battery after it has been in service”2. It is the most commonly used discharge test method and it determines if the battery is performing according to the manufacturer’s specifications and/or if it is within acceptable limits.
