Works like normal batteries no complaints we recommend

Purchased a 4 pack to replace batteries in all my detectors. These energizers do the job. The price was great, delivery was quick. 4-pack is the right size because I have 4 detectors. Energizer batteries last the longest. Good product for a fair price price.

Used a different batch of batteries for awhile that had horrible lifespan but these ones have been going strong for me much longer.

Energizer MAX 9V Batteries (4 Pack), 9 Volt Alkaline Batteries, good batteries for the price, good service, fast shipping.

Great products.. we use them in smoke detectors which we have 9

I purchased these batteries due to my previous batteries in my smoke detector alarm going bad, these new batteries are excellent and definitely worth the money. Ill be buying more to put in my other smoe detector alarms throughout my house.

they worked well and have held a long charge for my fire alarms in my house for years

My Panasonic transistor radio was not working properly or finding the stations I was looking for even when I turned the dial. I replaced the battery and low and behold it works as good as it did when I got it for Christmas in 1972

You know the quality is going to be good and it's going to last long if it's an Energizer battery. Use the 9 volt in my smoke detectors, They tend to be pricey, but with a sale and a bonus certificate it was a great buy.

Energizer Max 9V are great batteries to keep on hand for spares!

Energizer bunny batteries. Need I say more. Work like they are suppose too

The batteries are great for smoke detecters. These batteries can last longer than most. I've used these before and change them once a year. I suggest that anyone should buy the following batteries. Great product!!!

Works as intended. I believe that the battery life is almost as long as its main name brand competitor.

Batteries share a great Quality product. Great value on large count pack.

I like that these come in a 4 pack, 4 smoke detectors, 4 batteries. 9v cost a little more but I used a $5 certificate so it made these a good deal. They last way longer than a year so well worth the cost

These 9 volt batteries were on clearance. They are great batteries at a hood price. I should have bought a few more.

Very good battery last one on the shelves I was very lucky

I love this batteries because I used every year for alarm systems plus outside garage door opener program.

They keep going, and going, and going. Very trusted and well liked: plenty of juice, while others go out faster.

Not much to say here he’s a batteries they work plugged into my smoke detector I change the batteries for these every six months never giving me a problem
