Query: Shockingly Bad Performance

These batteries suck, after one year of use, they fail at an astonishing rate, do not hold a charge after being charged and then stored for later use, and do not last in electronic devices, even when they are fully charged before use. They are ridiculously overpriced for the number of uses I get out of them.Do the right thing, buy Eneloop instead.
