"What is dead may never die." That's easily one of the best lines (and episode title) from HBO's Game of Thrones series. While the saying may ring true for the Ironborn, it's not quite as catchy when it comes to batteries.
Will smartphone batteries ever last as long as we need them to? Perhaps not. That's why we rely on external batteries to help us stay connected for hours, even days, longer than usual. But in 2018, you don't want to use just any external battery. Modern Android phones have fast charging — so should your portable charger.

We've all been there. Channel surfing lazily whilst reclining on the sofa—then all of a sudden, the remote stops working. Out of frustration, you hold the remote up higher, press the buttons harder, or maybe a even give it a good smack hoping that will fix it. Right around this time, you start to wonder if your trusty old remote has finally called it quits or if it's just a dead battery.
The old "my battery is dead" excuse for not calling your mother may soon be a thing of the past. A team from the Korea Advanced Institute of Science and Technology (KAIST), led by Professor Jo Byeong-jin, has developed a "wearable thermo-element" that can be built into clothing to power your electronic devices. The science behind the innovation converts body heat (thermal energy) into usable electric energy. Made with lightweight glass fiber, this small thermo-element strip can produce about ...
What's a penny worth these days? Not much. But could there be some free energy hidden inside your spare pennies? You'd be surprised! See how I hack together stacks of pennies into makeshift batteries that can drive small-current devices like LEDs and calculators.

Can you recharge non-rechargeable alkaline batteries? Yes you can! Gary Cutlack from techdigest.tv risks chemical burns to demonstrate.
Nicad batteries often die in such a way that they won't take a charge and have zero voltage. This usually means they're shorted out by crystal dendrite growth. Here's a method of bringing them back to life by zapping those shorted crystal dendrites away with too much current and/or voltage. We'll use a welder as a power source. You could also use a car battery, a DC powersupply, or almost anything with some voltage. Charged-up capacitors are popular for this because you can get a very fast pu...

You may or may not know it, but getting rid of old batteries is a problem nowadays. Buying alkaline batteries from the store can be bad news, since these cannot be reused or even recycled. They end up in land fills and can pose serious toxic threats. Buying recycled batteries from the store is a better way to go, since these guys can be recycled and of course, reused. So check out this tutorial for some more adivce on properly disposing or your batteries. Good luck and enjoy!
This video shows us the method to make your laser pointer work with AAA batteries. Take a metal casing made of metal. In the video, we take a Duracell mini flashlight and remove the front and back part. Unscrew the top and back of the laser pointer and remove the batteries. Roll some aluminium foil and put it in the metal casing. Put the AAA batteries in the casing with positive side inside. Put the casing and the laser pointer together and the laser works. Bind the two together by two rubber...
Take apart a 9V battery and turn it in to Six AAA batteries. This way you save money. amazing science experiment trick. This is a simple battery deconstruction that results in a 9 volt battery's dissection into six AAAA batteries. They are not AA or AAA, but a kind you won't find at Radio Shack.
