Rechargeable batteries are getting better and better, and they have the potential to save you some money.
Still, they are not perfect and they remain more expensive than conventional alkalines. That makes it pretty painful when its time to throw them away.
Or, maybe it’s not time after all if you try this trick.
Take a pair of rechargeable batteries and hold them together negative pole to negative pole, so that the positive terminals extend out in opposite directions.
Now, take a pair of tongs or a similar metal kitchen tool to connect the two positive terminals together. Hold them this way for about 30 seconds.
Now, put them back in the charger. There is a good chance that they will now accept a charge again.
