Long lasting
The voltage is perfect for my son's toy cars, and it lasts a very long time. It's also easy to use. It works for remote control cars; I forgot to buy batteries for a while!

Very reliable and long lasting
I’ve been using these in my smoke detector and they’ve lasted really well. They hold power for a long time and don’t suddenly die out. I like that they feel reliable, especially for safety devices. A little more expensive, but I trust these more than cheaper brands.

Short life batteries
Bought a 4 pack and replaced in smoke detectors. Lasted 9 months in one before it started chirping. Do not trust that the others will last either. Company would not reimburse cost unless I took pictures of all the batteries, which would involve taking all the smoke detectors off the ceilings, sending in with email correspondence, etc. Not worth it-this is not a reputable company that they would not take me at my word that the batteries were inferior to go bad that quickly.

I’ve used the Energizer MAX 9V battery in a smoke alarm and it was quick and easy to install with a secure fit. The battery delivers consistent power and hasn’t shown any drop in performance so far. Packaging is sturdy and clearly labelled, making it easy to store safely. Overall, it feels reliable and well made, which is important for devices you depend on. I trust Energizer for long-lasting performance and peace of mind.

I Love Energizer Max!
These 9V2 batteries by Energizer Max are hands down the very best! The quality is good and they work great! The packaging is totally on point and it's a piece of cake to use! I really like that the pack includes two 9V2 batteries! I think it's great that they have long lasting power for my everyday devices as well! Overall I give this product two great big thumbs way up and would definitely recommend it!

Poor performance
Had to replace in less than 2 months. Smoke alarm battery. Poor performance.

Thank you for submitting your Review. Joe ! We apologize for the inconvenience caused. Many thanks for you feedback on the new child-resistant packaging. We have changed the packaging format to be in compliance with Reese’s Law, which states that all button, coin and hearing aid batteries – and devices powered by those batteries – must be contained in child-resistant packaging that features specific warning copy. The products have been subject to rigorous independent tests, confirming that the new packaging is 100% child resistant*, and zero batteries were accessed by children during CRP testing.* The new plastic dial includes additional staking points for extra security. By that nature it does mean that there will be a difference for users in how to access batteries in the pack, compared to previous packaging. The independent testing also showed that 99% of seniors were able to open the pack for the first time in under one minute*. On the second attempt, this time halved* so we found that consumers become faster with more familiarity and with instruction. We want to support everyone through the transition to child-resistant packaging and have prepared the following video that shows you how to open the pack. https://youtu.be/Si6aKj-1doQ Please reach out to us on 1-800-383-7323 or email us on customersupport@energizer.com to assist you better.

Reliable 9V batteries with consistent voltage and
I’ve used Energizer MAX Alkaline 9V batteries in smoke detectors and other household devices, and they deliver consistent voltage and dependable functionality. Capacity feels solid, with long runtimes before needing replacement. The weight is standard for a 9V and fits securely in devices without looseness. Overall performance is stable, reliable, and exactly what I expect from Energizer.

Reliable, long-lasting 9V battery that’s worth pay
I’ve used Energizer MAX 9V batteries in smoke alarms and a few other devices, and they’ve been really dependable. They last a long time, which is nice because changing 9V batteries is something you don’t want to do often. I haven’t had any issues with them dying suddenly or not working when I need them. Even ones that have been sitting in a drawer for a while still work fine. They do cost a bit more than some cheaper brands, but I think it’s worth it for something you can rely on, especially for safety devices. Overall, they’re simple, reliable, and do exactly what you expect without any hassle.

The Bunny just keeps going!!
Just replaced several Energizer 2430 batteries in our house! Also replaced the 9V in our smoke alarms!! Something about those Energizer bunny commercials got me hooked - I love that I can count on them to be top quality, don’t have issues with quality or leakage and are fairly priced.

Love Energizer
I just had 10 year sealed smoke alarms installed. I don’t need 9 V batteries except for my outside garage door code opener. I am glad I was able to find a two pack for a decent price.
