Electronic Testers: These are the go-to for quick and accurate measurements of a battery''s performance metrics like voltage, capacity, and resistance. Hydrometers: Used for lead-acid batteries, they measure the specific gravity of the electrolyte, which tells us about the battery''s state of charge.
A multimeter can be used to measure the voltage of a battery, which can provide an estimate of its remaining capacity. However, this method is not as accurate as a full charge and discharge cycle. To use a multimeter, set it to measure DC voltage and connect the positive and negative leads to the corresponding terminals of the battery.
Arduino can be used to measure the voltage of a battery, which can be used to estimate its remaining capacity. To do this, connect the positive and negative leads of the battery to the analog inputs of the Arduino.
Methods for Measuring Battery Capacity The discharge method involves fully discharging the battery under controlled conditions and measuring the total energy delivered. Ensure the battery is fully charged before beginning the test. Use a resistive load, such as a light bulb or resistor, that matches the battery’s rated current draw.
The standard procedure for conducting a battery capacity test involves charging the battery to its full capacity, then discharging it completely while measuring the amount of energy it produces. The test should be conducted under controlled conditions, with the battery at a specific temperature and discharge rate.
Resistance to corrosion and temperature fluctuations are significant attributes of high-quality test equipment. The instruments duty cycle and the maximum power rating also heavily contribute to the usefulness and longevity of the equipment. Long-term battery testing requires test equipment to run continuously.

Capacity is the leading health indicator of a battery, but estimating it on the fly is complex. The traditional charge/discharge/charge cycle is still the most dependable method to measure battery capacity. While portable batteries can be cycled relatively quickly, a full cycle on large lead acid batteries is not practical for capacity measurement.
