Apart from making better door stops, what advantage do lead-acid batteries have over lithium ion (Li-ion) batteries? The answer is that they are easier to charge. Apply 13.8V to any nominally 12V lead ...

Although not a new device, the LM317 is still a high-performance regulator. Its output voltage is essentially immune to fluctuations in load, supply voltage and temperature and this makes it ideal as ...

Editor’s note: Battery charging in a float or maintenance mode has been around for a while, especially for standby power, emergency lighting, telecom, uninterruptible power, and other critical power ...

Although important, neither consumer electronics nor electric vehicles are the main forces behind the growth in new battery technologies—instead it’s coming from “everything else.” This file type ...
