Energizer 123 Lithium Batteries (2 Pack), 3V Photo Batteries

Our glass break alarm sensor is very particular when it comes to batteries. I have tried off-brand ones only to find out that the sensor refuses to work. Energizers are instantly recognized by our alarm sensor as soon as I place them in the sensor! They last far longer than I anticipate as I change them very infrequently!

Had to buy these to replace batteries in an alarm sensor, and no store carried these. Hopefully these will last for years to come.

I'm always an energizer kind of person just to be honest.These perform as expected, using them in wireless home security products.They measure 3.2v out of the package.The service life is great. Years in my applications. 2 of them are in a garage with temps fluctuating from 20f to 110f on the regular and last the same as ones indoors at 78 year round.

The non-rechargeable batteries work perfectly in my Protac HL USB flashlight. Previously, I bought an aftermarket rechargeable battery, but the flashlight did not function properly. Since the flashlight is not used often, these Energizer lithium batteries (2 per flashlight) are a less expensive option compared to a new Protac rechargeable battery.

This 2 pack battery set has a 10 year shelf life. It cost $9.00 which is pretty expensive. I bought a similar battery on Amazon named Tenergy and it’s less expensive for a pack of ten. I believe that the Tenergy battery pack is about $20.00 so it’s 1/4 the price per unit of the Energizer.

Good product

Batteries! You just need them and for this flashlight it had to be this battery. I looked around several hardware stores and they didn’t have this battery or they were very expensive. Found it on Amazon at a good price. Delivery in a couple of days. Flashlight has a bright and useful light once more. A good buy.
