I've had issues with batteries on Amazon in the past but these are OK. Fully charged and work well.

Too soon to tell about longevity.

After reading so many reviews of 1/2AA batteries arriving dead or low I was hesitant to buy any on Amazon. But then I saw that buying this size anywhere was next to impossible. But I needed them for my Eve window sensors, so I bought this pack and a cheap battery tester.Mine arrived in a plastic clam-shell, with each battery in an individual little zip-lock baggie. All tested at very close to full, and all my sensors reported 100% battery on installation.

seems to do the job. have purchesed these in the past and have had good success.

I bought these as spares for a pair of zwave temperature sensors. The sensors came with batteries that have just now gotten low after 10 months in service. When I went to replace with a couple of these SAFT batteries, one sensor showed low battery but functioned ok. The other worked for a few hours and died as well. I put the original batteries back in and at least they are working. I can't imagine any quality battery would discharge down to 10% charge after 10 months of cool, dry storage. I have quality testers - primarily a ZTS MBT-1 pulse load multi-battery tester as well as a Fluke 75III multimeter for voltage. Volts read lower than on my original batteries, but my original batteries won't even test out on the ZTS. I will attempt to exchange these for fresh batteries and will update this review as to the outcome if I have more to report back.

Perfect in a pinch and you can't beat the value. My security company sells these for 2.5 times the price here and they are the exact same brand. Always have extras of these specialty batteries on hand. In my case each security sensor in the house takes one so I'm prepared. In my experience the shelf life is very good.

These are the batteries for my alarm sensors. The last set lasted at least 3 years, so I will not know how good these are until they survive that long. But, they have lasted long enough that I don't think they are bad.
