Review: Ecobee sensor batteries - I have to use these for battery replacement on my ecobee door and window sensors. No one carries this size, not even Home Depot, ACE or Menards. Even went to an auto parts store they don’t carry these either. There pretty thick in size but do work great. I usually have to replace these in my sensors every year so I’m not sure if it’s the battery quality or b/c we are in a colder climate. I know desertcart is the only place i can find these so I try to keep them on hand as sometimes I have received a dud battery in the package.
Review: Battery for alert necklace came quickly - Prompt, reasonable price and the item was available unlike my experience locally.
