Energizer Max 9V Batteries - Alkaline Battery

Everything was wonderful

I don’t receive this item, I searched all bags

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.

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.

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.

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.

Great, long lasting batteries.

Great for smoke detectors

They are good

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.
