The circuit described here is eminently suitable to indicate the capacity of a battery. We use a cheap electric clock for this. By connecting a resistor across the battery terminals, the battery is ...

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 Arduino based battery discharge monitor aims to provide an estimation of the capacity left in the battery by measuring and plotting its discharges. This Arduino based battery discharge monitor ...

Ricoh has introduced a battery protection IC for rechargeable one-cell lithium-ion and lithium polymer batteries which incorporates a two-step excess discharge current detector, used with an external ...

Using a MOSFET as an ideal diode can provide robust and reliable safety protection for the emerging generation of autonomous appliances, as Shane Timmons explains. The growing popularity of cordless ...

If you're a beginner electronics hobbyist you know that the capacitors on most battery-operated objects aren't powerful enough to kill you but can still provide a painful jolt of electricity if not ...
