Customer Ratings & Reviews

You know that smoke detector low battery warning will go off in the middle of the night while your sleeping! The extra expense for lithium batteries is a small price to pay for peace of mind. I put them in any important device-especially the ones you don't want a traditional alkaline battery to leak in! I have had numerous instances where "bargain" alkaline batteries from the store that begins with a "C" and ends with an "O" have failed and leaked before reaching expiration dates-including recently when properly stored unused batteries leaked while still in the package!

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

these last a long time and they keep our door lock working hard, the August lock keeps me from getting locked out

Hands down the best brand and line you can purchase. Use them for firefighting lights cannot afford to take a chance

The Energizer are great batteries. I brought for my alarm glass breaker,

My husband uses these for his flash light. He loves them! They last for about a month too. Mind you, he uses his flashlight 5 nights a week at work.

Puppies batteries for Arlo cameras they work wonderful last a long time and love the quality and quantity that come in the package

Perfect product as mentioned and right price at the store

Just keeps going and going in my flashlight strong output of light

This is just what I needed! It works well and keeps going and going.

this brand of batteries is the best. never have a complaint about battery life and all of my battery operated products are functioning great and for a long time

Good batteries long life does the job I need them for.

They work great in my water purifier, not cheap though.

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

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

Great product for the money, long lasting for a good price.

[Employee of bestbuy] they last very long and a great battery for my camera

The battery has been reliable. It is supposed to last longer than other brands, but I have not been able to establish it yet because it has been in use.

I needed these batteries for my ADT smoke/CO detectors and they were in stock for immediate pickup. They are a bit unusual to find and I didn't want to wait to receive from Amazon.
