Leaked killed my smoke detector! Latest batch says best by 9/23, would not gamble on it.
Hey, thanks for the heads up. You probably saved me from having to replace my smoke, CO2, and water detectors.
I’ve ordered these in AA and AAA types before and was impressed with the quality. Compared to all the other off-brand batteries (i.e. not Energizer or Duracell) they were excellent. I can speak to the 9V type, and when it comes to smoke and CO detectors, I would always suggest Energizer. Those are too important.
