6 FAQs about [Lead-acid battery discharge time test]

What is battery discharge testing?

What happens when a lead acid battery is fully charged?

A fully charged lead acid battery when subjected to discharge testing typically shows a phenomenon at the beginning of test known as coup de fouet.

How long does a battery test take?

None of the cells showed any problems. Battery manufacturer’s published discharge times range from 1 to 20 hours or more. It is preferred to test the batteries in a reasonable amount of time. A performance test with time duration of 3 to 4 hours is common; however shorter test times require higher loads.

How do you test a battery?

There are several methods: constant current discharge, constant power discharge, constant resistance discharge that can be used to perform a capacity test, but the most common method involves discharging the battery at a constant current until the voltage drops to a predetermined level.

What is a minimum voltage for a battery discharge test?

It is suggested that a minimum voltage of 0.05Vpc below the minimum average accepted as a pass at the end of discharge time at 83% of the discharge time. For example, if the discharge test has to run for 10m with a minimum voltage of 1.65Vpc, then every cell shall have a voltage of not less than 1.60Vpc after 8m 20s.

What is a battery performance test?

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.
