Customer Questions

  • Are Allmax batteries rechargeable?

Allmax batteries are not rechargeable. Please DO NOT try to recharge alkaline batteries, which could lead to battery leakage or explosion. Alkaline batteries and rechargeable batteries are not interchangeable. You cannot recharge an alkaline battery.

  • What is the capacity in mAh of the battery?

The battery’s mAh determines how long the battery will last, and performance varies based on the type of electronic device you use. When you use our batteries in smoke detectors, Allmax’s 9V batteries have a capacity of 720 mAh. This is good.

  • Where can I find the expiration date?

You can find the expiration date on the body of the battery or on the box. It is marked with a “Best Before” date. Our Allmax 9V battery has a 7-year shelf life, meaning under proper storage conditions you can use it any time before this date.

  • Will the battery fit in my device?

They usually do. For example, the height of our 9V batteries is 1.85 inches with an outer diameter of 0.66 inches. This conforms to IEC standards. So if the size of your battery compartment is designed to IEC standards, our batteries will fit.

  • How are Allmax batteries packaged?

There is an Allmax 9V battery tightly wrapped in plastic shrink packs, with 24 shrink packs per package that are well-packed in boxes that are easy to open, easy to stock, reclosable, and impact-resistant, so your batteries are always protected.

  • Can I store batteries in the refrigerator?

Not a good idea. It is best to store batteries in a cool, dry place. We DO NOT recommend storing batteries in the fridge – this does not lengthen battery life. For safety reasons, please keep batteries away from children and heat sources like fire.

  • Are batteries affected by temperature?

Extreme high or low temperature is not good for batteries. DO NOT use or store batteries at high or low temperature. Low temperature may cause battery discharge capacity to drop, while high temperature may lead to battery leakage.

  • What should I pay attention to during use?

Please remove the film around the battery before using it. Check whether the anode and cathode of the battery compartment of the device are normal, without dirt and rust. Do not mix old and new batteries or batteries of different types or brands.

  • How can I track the status of my order?

Should you have a question or concern about the delivery of your order, please contact Amazon through their website or by calling their toll-free number 08002797234. Together we work to ensure your deliveries are on time and in perfect condition.

  • What if I receive a broken or defective product?

If your box or product is damaged in any way, please contact Amazon. Amazon is responsible for delivering our products, so they will take care of your order. Should you need further assistance, please don’t hesitate to reach us through Amazon.

    Our smoke alarm started to beep driving us all mad. Ordered online and delivered quickly to resolve the issue.
    Good price for the pack and spares for when the others start thank you

    Found these store for.over a year in fridge and lose zilch. They are on par with the name brand alkaline from the retail store..I would.say it holds up longer than the silver classic household brand with kitty on label and the copper tops. Used hundreds over the years, and I keep cases in the fridge.

    Arrived before time well packed they seem to retain the power from the short time they have been in use.

    I ordered these for smoke detectors. The price was very good and based on previous reviews I decided to give them a go.
    They arrived promtly and are all indivually wrapped inside a fitted box, which is a nice touch.
    All working well so I assume they will be good for the job intended.

    Great for the smoke alarms. Can’t comment on longevity as I change them every 6 months

    We always buy in bulk. With 7 remotes, 6 smoke detectors, flashlights, clocks, battery operated candles and small strings of lights, we seem to be changing batteries in something daily These batteries seem to last as long as Big Name brands. And for much, much less. I would recommend them.

    See my other Allmax reviews, excellent packaging, shelf life and cost per milliamp. I recommend Allmax highly.

    Just what I needed for my battery case. Not many devices in the house need these, but the ones that do are the smoke alarms and the carbon monoxide monitors, and they always seem to need batteries at the same time.

    Golden Review Award: 2 From Our UsersBeen using a well known film companys cheap batteries OK to start with but now lasting a very short time, so I thought I’d try this make, I must say they are top quality and power seems to last a lot longer, I’ve used them in Smoke Alarms, Multimeters, used 4 at once in a signal Generator and some electronic projects all work well, more than happy and will buy again.

    as i bought these for long term use in smoke alarms and test equipment which is stored away in my toolbox without being used for long periods the leak proof is extremely important.
