Panasonic CR123 CR123A 3V Lithium Battery ,6 Count (Pack of 1)

CR123s are the batteries you only think about when something important goes dark or silent. A flashlight, a door sensor, an optic that picked a bad moment to quit. These are the real thing. Fresh date codes, full voltage out of the pack, and they have held up in a light that rides in my truck through a Texas summer and a couple of cold snaps. Lithium primaries shrug at temperature the way alkalines never will, and that is most of why you are buying them. The thing to watch is the market, not the battery. This size gets counterfeited constantly, so check the date codes when yours arrive and be suspicious of anything much cheaper. Also, these are primaries. They are not rechargeable, and do not confuse them with the lookalike rechargeable cells that fit the same tube.

These batteries were a great price and exactly what we needed.

Very good batteries, took care of my smoke detectors.

I do like these, easy to test with tester and install. I did NOT like ADT device not liking one of the two batteries needed on smoke detector near furnace. One only registered 3.1 volts and the detector would not recognize it. Had to make sure they were more than 3.0 volts for that ADT to recognize them. Moral, just put a tester on them before you replace older ones failing.

The batteries were fine but the wrap around them was ripped. The package they were shipped in was ok.

The batteries are compact and effective.

Good product. Worked as they should.

Just as ordered. Have an alarm system which calls for this battery and all is fine.
