sulfuric acid battery testing
Typical lead acid batteries today are made up of an electrolytic solution that consists of sulfuric acid and water. The most direct way to check the batteries and whether or not they need to be recharged is to determine the specific gravity (SG) of this solution: the higher the SG, the higher the state of charge of the battery.
For many customers, regular maintenance of batteries includes testing the SG of each battery cell periodically. Battery producers, on the other hand, measure SG as a quality control parameter and use it to ensure that working batteries reach their customers. These preventive maintenance and quality control checks ultimately save a lot in operation interruption and battery replacement costs, and contribute to maintaining safety in the workplace.
With the Density2Go, it is possible to measure SG, density, or compensated SG or density. This application note shows you how to measure the above values with your Density2Go portable density meter, including measurement parameters, setting measurement limits to identify if batteries need to be recharged, and results.
