How to Test Capacity of a Lead Acid Battery with a Source Measure Unit

Batteries are characterized by their ability to deliver the required current over some period of time, called Amp-hours. Also known as capacity, different types of batteries have different characterizations curves that show their amp-hours as a funciton of time. Veirfying the manufacturer's capacity after the battery has been used for some time is known as a battery charge-discharge test. In this video, applications engineer Barry Bolling uses a GS610 source measure unit to perform a charge-discharge test on a lead acid battery. Source measure units, devices that funciton both as a power supply and a multimeter/electronic load, are ideal for these types of tests.
