A discharge test carried out immediately after the installation or commissioning of the string is called an acceptance test. For lead acid batteries, the measured percent capacity must be at least 90% of the rated capacity for the battery to pass the test.

In summary, maintaining a low depth of discharge can enhance a lead acid battery''s durability. Limiting discharges to 30-50% of its total capacity leads to optimal performance. A lead acid battery lasts longer with careful management of discharge levels. What Are the Risks of Deep Discharge for Lead Acid Batteries?
While a battery is stored after m anufacture, it lose s some of its charge. The rate of self discharge is a function of grid alloy and storage temperature. Basically, for all lead -acid batteries, the rate of self discharge increases with storage temperature. The total charge lost is a funct ion of the time in storage at a given temperature. The

There are a number of standards and company practices for battery testing. Usually they comprise inspections (observations, actions and measurements done under normal float condition) and capacity tests. Most well-known are the IEEE standards:
IEEE Std 485TM-1997, IEEE Recommended Practice for Sizing Lead-Acid Batteries for Stationary Applications (BCI). IEEE Std. 1491TM, IEEE Guide for Selection and Use of Battery Monitoring Equipment in Stationary Applications. IEEE Std. 1578TM, IEEE Recommended Practice for Stationary Battery Electrolyte Spill Containment and Management. 3.
Most well-known are the IEEE standards: IEEE 450, “IEEE Recommended Practice for Maintenance, Testing and Replacement of Vented Lead-acid Batteries for Stationary Applications” describes the frequency and type of measurements that need to be taken to validate the condition of the battery.
Although the discharge test is a true test of the battery and provides valuable information, people are generally reluctant to do discharge testing, primarily because it is labor-intensive and time-consuming. It is also one of those tests that needs to be done right the first time on that day.
