PGSONIC 5 Pack CR2477 3 Volt Lithium Battery

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 amazon 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.

Prompt, reasonable price and the item was available unlike my experience locally.

Good quality, just couldn’t make them fit into battery replacement project that I was working on.

Good value and seem to last using.

I had two items that had tiny lights. One a paper letter opener & the other a pen. I found them in a drawer with no functioning light in each. Ordered the batteries, changed them in the devices, and now will keep them out to use at my bedside and small desk. Otherwise, these cool tiny devices would be in the landfill.

Great

As advertised

Good
