Small button- or coin-cell batteries power many of the portable consumer electronics in use today. Efficiently monitoring the health and state-of-charge (SOC) of these batteries without significantly ...

What type of equipment is best to use for low-voltage test of battery cells? What is an electronic load, and how does it work? How to overcome a major limitation with the low-voltage-discharge test.

This circuit prevents over-discharge of a lead-acid battery by opening a relay contact when the voltage drops to a predetermined voltage (lower voltage threshold). When the battery is recharged to a ...
