Customer Ratings & Reviews

Bought to replace my whole house fire and co detector system control module. It uses these batteries and is responsible for linking the whole system together so I trust these batteries

I go through these batteries like your average person goes through AAs or AAAs. So when I was able to find them in a 12 pack and also get a sweet discount for being a Best Buy Plus member it was a no brainer. Not sure what else you were expecting in a review of a battery. It is 3V and will fit devices designated for a 123 batter...

I have to buy these ever 6 months for my motion sensors in my security system. They suck to change but nice to have a Bestbuy near with them.

I have four Arlo cameras that are great; however, each one requires 4 batteries. The usual cost for four is 27.00 This package has enough for 3 cameras at less than the cost for two. Great deal!!!!

A 12 pack of CR123 batteries that I use for my flashlight and headlamp at work. 12 batteries at $30 works out to $2.50 per battery. That's a pretty good buy!

They work well until they die. They could be a little more affordable but they do work. Nice compact sized battery with a nice bit of power to them.

The batteries went out in my smoke detector and I need it replacements I was quite surprised when I opened it up and I saw this type of battery true the form they did last for about 10 years so if you're looking for something long lasting good quality this is the battery for you.

Energizer lithium battery 2pack needed for my golf rangefinder will last twice as longer great quality

These are great batteries. Please check the expiration date on packages that are mailed directly to your home and exchange immediately if the date is close to the expiration date. Otherwise, great batteries.

Great batteries. Batteries for my flashlight are hard to find. These worked great.

I like that they came in a 4 pack. I have to use these type of batteries for my home security motion detector. They work great and last a while.

these worked perfectly for my security cameras. they hold charge for longer than expected. good deal.

These batteries last longer than the other brands and I also think they work a lot better for my cameras I would recommend these to anyone that has cameras

These batteries are necessary for Arlo Netgear outdoor cameras. My automobile was stolen in front of my home two years ago and that is when I purchased the Arlo cameras. Best Buy always have these batteries in stock and I especially like that they have a (2-Pack) available so I can just purchase two packs as each of my cameras take four batteries. Many stores do not carry this battery or only have a 12-pack available which is quite expensive. I have always purchased excellent batteries at Best Buy and never have I had to return any because of not working properly.

Long lasting power in locator beacons. Durable and dependable in tough environments

These batteries ended up being a few dollars more than some of the others available. I tend to have better performance out of these. Maybe it's a placebo effect but these seem to power the flashes on faster and tend to last longer.

Picked these up for my high power laser pointer. They always last about 3 months on it. Great bang for your buck.

I needed two batteries and I got two batteries. The batteries powered the item that I bought them for. Would get again when these die.

Lithium batteries are not cheap but for outdoor items or electric door locks where cold performance is necessary, don't skimp out. They are also good on other mission critical things like the battery backup in fire alarms. In fact, with the longer life, why not pay more up front and get better life?

These batteries are still working with full power. I recommend these batteries because of longevity and power
