Low cost, but cheap
on January 7, 2010
I agree with jetpower. These seem like a killer deal, but the performance is terrible.
About 3 years ago, I bought two packs of 12, one to keep around the house for smoke detectors and other devices, and a pack to use at church in our wireless microphones.
They were okay for the wireless microphones, because forgetting to turn off the mics didn't really test the longevity of them. I'd probably buy them again for that reason + the low price.
But for home use, they just didn't last. Smoke detectors lasted about 4 months before chirping when the batteries were newer. After two years at home (shelf life dated 2011), the remaining batteries were dead. They come with plastic caps attached, so I know they didn't short out and discharge themselves.
Keep in mind, this was quite some time back. Have they improved? Not likely, but possible.
I have a Duracell Ultra in my bedroom smoke detector, it's been in there for about two years and is still running strong. But these ProCells, and my poor experience with AA rechargables from Duracell, have seriously weakened my resolve to buy their brand in the future.
I hope my experience is useful in your decision making process.
