So I have a bunch of 18650 4v cells that are only suitable for a flashlight or portable radio. Is there any way to revive these cells? I got 2 nicad packs from an older Harbor Freight impact drill that came back by a slow long complete discharge, but a complete discharge on a lithiu...
remove all the loose dirt and oil from the top of the battery with a dry cloth, giving particular attention to the areas around the vent caps; these must be free of debris before you open them. Undo the vent caps on all the battery's cells, unscrewing them by hand or by...

Of course, electronics without a power source are rather pointless. The same researchers have also found a way to make a soft, flexible lithium-ion battery that looks a lot like artificial leather. This material, too, can be woven into clothes to power a range of gadgets, providing hundreds...
