Connecting a battery in a circuit causes the current to flow through the connected circuit due to the movement of ions within the battery. Over a period of time, the ability of the battery to hold charge reduces. Measuring the capacity of the battery is the leading method for understanding its condition.
Reliable test equipment is required for testing batteries accurately. Crest manufactures fully-configurable test systems where you can program the complete battery testing profile. Testing the batteries after manufacturing and periodically thereafter, ensures timely maintenance which leads to a long service life. Replacements of batteries having failed under warranty can thus be avoided. Tests such as cycle life, capacity, and high rate discharge are important for accurately determining the battery health.
