This simple charger and capacity tester, which is built around two inexpensive and widely available modules, provides an ...

The true measurement of a battery’s capacity is essential for many scenarios. A capacity measurement device can solve the problem of spotting fake batteries as well. Nowadays fake Lithium and NiMH ...

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 ...

Gill's new TCT-1000 battery capacity analyzer is designed to simplify battery capacity checks for A&P mechanics because it automatically tests 12- and 24-volt lead-acid aircraft batteries. It doesn't ...

Batteries lose capacity over time. The process can be slowed down, but it’s inevitable, so after a few years, your EV won’t provide quite as much range as when it was new. The battery will lose about ...

Lithium-ion batteries are one of humanity’s greatest inventions. They have already helped us develop portable electronic devices and electric vehicles and are on the verge of conquering the grid ...

The 18650 is perhaps the world’s favorite lithium battery, even if electric car manufacturers are beginning to move towards larger cells such as the 21700. Used heavily in laptops and flashlights, it ...
