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

these batteries seem to last forever. fair price for what they are and reliable when you need it

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.

These batteries really do last a long time. We use them in our Ring CO/Smoke listener and we have to change them out only every couple of years.

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.

Ordered these for my wireless alarm,they don't last very long,but they work

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.

Easier than running to the store. Two pack batteries delivered quickly!

Exactly what we needed. Good price. replace every year but the battery life is much longer. Great power & strength. Long lasting .
