Meet the Next-gen Lithium-Sulfur Batteries
https://www.electronics-lab.com/meet-next-gen-lithium-sulfur-batteries/
What would you give for a battery, 5x the storage capacity of whatever you’re reading from? Well, the countdown to commercial availability for batteries of this type of capacity has already begun and it would be considerably cheaper than then currently available batteries. This radical improvement comes from using sulfur cathodes rather than graphite in […]
Battery (Lithium, NiMH, NiCd) Capacity Tester Using Arduino
https://www.electronics-lab.com/battery-lithium-nimh-nicd-capacity-tester-using-arduino/
The increased interest in IoT and electric automobiles around the world is driving an increase in the use of Lithium-Ion/Lithium-Polymer/NiCd/NiMH batteries as more devices and applications are using them, due to their high energy storage capacity to size ratio. This increased interest is, however, causing an increase in the number of batteries with “fake” ampere-hours […]

Free Elektor Article: 0-30V Lead-acid Battery Activator
https://www.electronics-lab.com/free-elektor-article-0-30v-lead-acid-battery-activator/
A well-known electronics store has been selling a very simple lead-acid battery activator for many years. Although I can’t prove it, my lead-acid batteries do seem to last longer since I started using the activator. The principle behind this circuit is very simple. The battery is loaded with a current of about 100 A for a […]
