If you have a "dead" rechargeable battery, do not dispose of it immediately. Try the following trick that might bring her to life. At least you have nothing to lose.
Usually rechargeable Ni-Mh batteries if not charged properly, they are likely to hold “μνήμη”Or even completely refuse to recharge. So if you have a rechargeable Ni-Mh battery that no longer refuses to charge, then before throwing it in the recycle bin, try the following trick. You will only need a second rechargeable battery in good condition and one…. tongs for barbecue !!!
Get a fully charged similar battery with the one that is "dead" (of the same type) and keep them so that the two their negative poles to be joined. Then hold their two free positive terminals between a pair of barbeque tongs. Actually just short the two positive poles. But not for long, just for 30 seconds. See how it's done below video:
This trick does not promise that it will work every time or on every battery, nor that if it works once on a battery then it will work again for a second time on that particular battery. Not even that it will liven up the battery with the same power chargings he had before he died. However, you simply don't lose anything by doing so. You had her to throw away anyway.
However, we wish you good luck.
I didn't expect it, but out of 4, 3 worked!!!!
Thank you very much!!!!
