Allmax 9V Maximum Power Alkaline Batteries (48 Count) – Ultra Long-Lasting, Leakproof Design, 7-Year Shelf Life, Maximum Performance (9 Volt)

I use these batteries in our summer home smoke detectors.i change them every 6 months so longevity is not a concern but good to know they last much longer than my needs. They have plenty of power left when it’s time to leave but I still change them to keep on schedule. The price plays a big part in my purchase, much less than the usual brand names. Definitely worth a try.

No complaints. I have purchased several times and they last just as long as name brands. The price point is why I go with this brand.

They arrived quickly, they work and the price is right. Not sure how long so will add the 5th star later.

Many brand choices for batteries, unfortunately few are made in the USA. I've had the occasion to use Allmax in various sizes. Did some research and the quality of these are great especially considering the price. Excellent performance as well.

I play in a 6-piece western swing and honky tonk band, and typically have at least two guitars with wireless connections to my amplifier. The belt packs use 9-volts, and they are power hungry. Most of the time they will eat a 9-volt up after 2 x 4-hour shows of solid playing, so you can imagine how many 9-volts I need playing 20-40 shows per year part time. I have been using these for about 2 years now, and they get the jo done at about the most reasonable price I could find for 9-volts. I do wish they came with the little black plastic caps that snap over the terminals to prevent the batteries from discharging should they come into contact with other metal things in my gig bag, but I've simply kept a few of those handy from past brands I've owned and use them on these once I remove the wrappers. Other than that . . . they are awesome and a decent value.

Another one of my smoke detectors started chirping because the battery was getting low. Of course it is the one in the living room which required me using a ladder to get too. Check my box of batteries and all of my 9v batteries were dead. I decided if I was going to buy a battery for one smoke detector then I might as well buy enough batteries for the other 4 dead smoke detectors. Now all of my smoke detectors have batteries and I won't have to worry about them chirping for many years to come.

Came in fully charged, Allmax have been a good source for quality affordable batteries.Recommend.

I have been ordering Allmax batteries in various sizes for years. Great shelf life, always work and it is so nice to stock up batteries and not have to run to the store everytime something goes out. We are in Florida and with the threat of hurricanes, it is important to be prepared at all times. Each May we carefully inventory our stock and batteries are at the top!! Having batteries we can depend upon when the power goes out is the link to making things work and sitting in the dark. We have compared to name brands and the Allmax stand up equal.
