Battery Discharge Testing: A Comprehensive Guide to Testing

In electricity, the discharge rate is usually expressed in the following 2 ways. (1) Time rate: It is the discharge rate expressed in terms of discharge time, i.e. the time experienced by a certain current discharge to the specified termination voltage ch as C/5, C/10, C/20 (2) C rate: the ratio of the battery discharge current relative to the rated capacity, that is, times the rate.

Battery Capacity Test

For a lead-acid battery, the test time is approximated to be near the battery''s duty cycle. Most lead-acid batteries have a duty cycle of 5-8 hours and this is the timeline used and the end discharge voltage is usually 1.75-1.8 volts per cell or 10.5-10.6volts. To get the best results, use the same testing times in the battery''s lifetime to

6 FAQs about [Lead-acid battery discharge test comparison table]

What happens during discharge of a lead acid battery?

During discharge, electrons are passed externally through the load while internal chemical reactions at the interface of the electrolyte and the electrodes work to balance the charge equilibrium. Figure 3 illustrates the chemical states of a fully charged and discharged lead acid battery.

What is a battery discharge test?

Among all the tests, the discharge test (also known as load test or capacity test) is the only test that can accurately measure the true capacity of a battery system and in turn determine the state of health of batteries.
