Odd size.They fit a cat toy, only place I could find it.

Works great no issues using them and them not working I always trust energizer for my battery needs,. Don’t forget to check your battery needs for devices you gift To others!

They got an old clock back to running. We'll enjoy our waterford crystal clock.

My wife and I have a special clock in our living room that uses this N Cell E90 Battery. Most places do not carry it but as I was searching for one I found it at Best Buy. Wow, thanks guys for carrying a hard to find battery.

I was so happy when I discovered that Best Buy carried these odd-sized batteries. I had an old Lenox clock that had been a mere decoration on a shelf for years. Now, she runs again!

I have a small clock that takes batteries that are not stocked at most stores. I went to Best Buy and there they were in stock. The Energizer N Cell E90 battery got my clock running again.

I have two items which use this N/E90 battery, so it is great to find a 2-pack for about the same price elsewhere for a single battery.

These N Cells are not super easy to find. They're not common. But my son has this toy (Anki Cozmo) and it has 3 cubes that use these and I was glad to find them at Best Buy.

I always buy the competition so I was surprised how long this lasted. Years ago it was like a generic. Now it seems like the quality it should be for a brand.

Works as expected. Last pair lasted a couple of seasons of use on my bicycle 3 LED tail light.

I really like these Energizer - N Cell E90 Batteries (2-Pack) are really long lasting. I feel like they last twice as long as other brands that I have used.

Strange battery type, it seems. Not always easy to find, but was glad they had a two pack at BestBuy. I use for a clock that takes these N size. They seem to last a few months in the clock before needing replacement.

I use a HP 19BII calculator for work and these batteries are the ones that fit this calculator. I find the Energizer brand lasts longer than cheaper competitors so it's worth paying a couple of dollars extra.

I use these specialized batteries in a high powered flashlight that requires them. They seem to work well, have lots of power and last reasonably long. I am pleased with their performance.

good batteries that have lasted a good while and done their job. work pretty well and not had any problems with it so far.

Use these for our security devices. They last a long time. I recommend this battery for its long life in motion sensors and glass. Break sensors.

They're batteries. The did what they were supposed to. My son needed them for his robot, they worked like a charm, He's happy!

It was a lot easier finding these inside Best Buy compared to WalMart or Target. They fit the garage door opener perfectly and I was in and out of the store in under 5 min.

I really love these Energizer - N Cell E90 Batteries are reallly long lasting and nice quality. I really like that it comes in 2 pack so I can have extra when I need it

I'm glad Best Buy carries this sometimes tough to find battery. Energizer is top quality and the 2-pack is a great value.
