Customer Ratings & Reviews

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

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

Great product for ring alarm sensors, last lot of time

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?

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

The batteries work as they should. I hope they will as long as they say that they should.

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.

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.

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

Expensive but lasts longer.No need to worry about leaks

The batteries lasted a good amount of time for my flashlight. Great product and will stock up more soon.

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

Excellent value. We use for outdoor cameras. Long lasting

purchased as replacement batteries for my security system glass break units. excellent price and expected long lasting usage.

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

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

Energizer is my preferred brand of batteries for use in my security cameras. This package saved money compared to buying smaller packs.

One of my Smoke Detectors began chirping after we left for a vacation. I had some friends go to our house and see about changing them out. Unfortunately they weren't the typical 9 Volt type and my friends went to our local hardware store to purchase them for us, but could not find them. So I just had them deactivate the alarm for that sensor (I have multiple smoke alarms in my residence anyway) and found these at my local Best Buy. I got them for for $7.99 sold 2 in a pack which is what I needed to replace. I would have bought more, but they only had one pack left. Everything has been fine since the replacement, but need to find more of these for the other detectors.
