Tenergy CR2 3V Lithium Battery Non-Rechargeable PTC Protected High Performance CR2 Batteries for Flashlight, Digital Cameras, Toys, Alarm Systems, 10 Pack

great battery. lasts as long as the big brands.

I use them for my golf laser yardage tool. Good price

I was glad when they came it works good with my smoke alarms in the house

Very pleased with the batteries although they seem to last less than others I have purchased

Great price for the punch! Long lasting for electronics.

Great

I am extremely pleased with these batteries. I bought a 20 pack back in March 2023, didn’t use them all and have a few leftovers. I put them in my Smartthings device tonight, it still register 100%. After 2 years and 4 months sitting in the drawer, the batteries didn’t degrade at all.

I have been using "name brand" batteries for my GPS for years. I was able to purchase 10 batteries for less than 3 of the other batteries. I have only been using Tenergy batteries for a few weeks so I can't comment on the battery life, but, so far so good.

Exactly what I needed and are the perfect ones for my window sensors. Thank you.

They arrived super fast and you can't beat the price. These work out to be much cheaper than other brands I've used in the past. I use it for my door sensors for my home alarm system. The work great and are long lasting. My review is based on a daily low usage but I'm sure they work just as well on these power hogs. I would definitely recommend this product!

Works like other name brands but more value due to price

Bonnes
