Battery discharge testing, also known as battery load testing, is a process that test battery health statement by constant current discharging of the set value by continuously the discharge current from a fully charged state and then measuring how long the battery lasts.
6.1.6 If due to some reasons (for example: size or mass), battery pack or system is not suitable for some tests, then, after reaching a consensus through negotiation, the manufacturer and testing institution may use the subsystem of the battery pack or system as the test object for all or some of the tests.
6.1.4 Battery pack or system test delivery needs to include necessary operating documents, as well as interface components required to connect with the test equipment, such as: connectors and plugs, including cooling system interfaces. The typical structure of battery pack or system is shown in Appendix A.
For any type of battery technology, discharge testing it from its fully charged voltage down to its discharge voltage level, is the one true accurate measurement of its capacity and performance. For a small single battery, a discharge test is not to onerous.
As with all battery packs, the ultimate proof is a discharge test, so one was carried out on the to older battery packs. A discharge current of 1.4 A was used, which should have given a 1 hour duration for the test. The 03-2009 battery pack shown in blue, shows a reasonable discharge curve that tails off to the minimum voltage of 14.8 V.
Although many tests can be performed to assess the condition of the batteries such as ohmic testing, specific gravity, state of charge etc., only the capacity test, commonly referred to as the discharge or load test, can measure the true capacity of the battery system and in turn determine the state of heath of the batteries.
