I’d like to poll people’s experiences with the replacement batteries for ST sensors.
Here is my story:
I had 2 ST motion sensors which with the original Panasonic batteries last from at least 6 months to a year. When they went offline I figured the batteries were depleted I replaced them with Panasonic batteries I ordered from amazon (third party sellers because amazon doesn’t carry them). None of the two was able to reconnect to the hub after battery replacement. I figured may be the sensors went bad, probably the reason why they were offline to begin with, so I bought some iris sensors to replace those ST sensors and didn’t think much of them…they didn’t work so well to begin with…
However, just 2 days ago. One of my leak sensor went offline with battery status of 0%. This senor worked great for close to a year I think and it had triggered a few times so I was very happy with it. I replaced another Panasonic battery from amazon, and it reported 100% and I thot all was good. However, in less than 24 hours I noticed the battery level dropped below 90%, then the 2nd day, it dropped below 80%…
This got me thinking, may be the “new” batteries I bought from amazon (third party seller) were problematic. Though the batteries all have Panasonic logo on them, they all came in generic seal or even “zip-loc” style bags, with no branding on them. So I have no way to tell if they are really new batteries or even authentic Panasonic batteries.
I have not been able to find these batteries from retail store, so I just got them from amazon. I’d like to know if there’s a better place to order these types of batteries, so I can have a higher confidence that the batteries are good to begin with?
EDIT: I checked my amazon order history: The CR2450 I ordered were actually sold by amazon, but the question about the batteries remains.
