The Eternal Flame of Tiny Power” Let me tell you about this Energizer 9V battery — the Chuck Norris of electricity. I bought one in 2008 for a smoke detector. That smoke detector has since witnessed three apartments, two breakups, one existential crisis, and a mysterious incident involving microwave popcorn and regret. The battery? Still going. Probably judging me. Last week, my friend’s Bluetooth speaker died mid-party. I pulled this battery out of my smoke alarm like a defibrillator in a medical drama, snapped it in, and boom — instant resurrection. I’m convinced these things aren’t powered by chemicals — they’re fueled by pure spite and determination. If the apocalypse comes, the only survivors will be cockroaches and 9V Energizers. 10/10 would trust to power my smoke alarm, my hopes, and maybe my next relationship.

Reasonable price and brand name alkaline batteries.

I use this for my active pickups in my Zakk Wylde gibson les paul, get a long lasting drive out of them, and always reliable, without being too expensive too!

These are really great. I use them in my smoke alarms. They last a very long time and I don’t have to worry about changing them very often. They are also a great value.

Great batteries, last so much longer than the ‘cheaper’ versions. Very happy with the packaging and the durability of them. Will be buying again.

It got the job done. No more chirping from my smoke detectors.

The Energizer Max 9V battery is decent and does the job, but nothing exceptional. It works fine for low-drain devices, but I found the lifespan to be shorter than expected compared to some other premium batteries. Reliable in the short term, just not the longest-lasting option for the price.

Got this 4 pack to replace batteries in our smoke detectors. Replaced the one on vaulted ceiling in primary bedroom as it requires a tall ladder and is a pain to get to, but also happened to be the one that had alerted us it was time for a new battery. Day 1, fine. Day 2, alarm started chirping again, indicating a new battery is needed. All that effort and the expense of these batteries for nothing. Very irritated!

Excellent batteries that work well and last a long time. I always choose this brand. I highly recommend them to everyone. I usually buy them for children’s toys. My child plays with the toys very often, and the batteries handle it well.

Long Review (English): Energizer batteries are a great choice for anyone looking for reliable and affordable power. They perform very well in everyday devices like remotes, clocks, toys, and flashlights. One of their strong points is that they are widely available and often a little cheaper than Duracell, making them a very convenient option.

Great for smoke detectors and other essential devices. Long shelf life and leak-resistant design make them a trusted choice. Good packaging.

Great product. I use these batteries with some of my children's toys. They last a really long time, which is not only great for the environment as they dont need throwing away as often but also great money wise as dont need to buy them all the time.

Great 9 volt battery from Energizer! We use these in smoke detectors and the like and the last forever. They preform as expected and are fairly priced.

Energizer Max 9 Volt batteries are a must have. They offer a 5 year shelf life, which is important because these are the batteries we use in our Smoke detectors. For this reason we must use long lasting batteries that are reliable and most importantly from a brand we trust when protecting our loved ones

My favorite batteries.

Compatibility is awesome. Long lasting duration and packaging is beautiful. It is valuable economy. Highly recommended for everyone in need

I’ve used Energizer MAX 9V batteries in various household items like smoke detectors and wireless microphones, and they never disappoint. They have an impressively long shelf life and hold their charge for months, even in high-drain devices.
