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 48 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.

Safety first but money talks in these austere times. 4 batteries for less than the price of one from the DIY store down the road.
Really well packed. Delivered quickly. Fitted in 4 smoke alarms in minutes. No more squeaks in the night. They work perfectly.
Buy these with confidence. 5 stars all round.
Price was right I needed 5 for smoke dectectors. Arrived quickly
Bin sehr zufrieden, halten solange wie andere Marken Batterien, sind jedoch preisgnstiger.
So far, so good. For use in household smoke detectors. Will update later this year once longevity can be determined but the initial charge seemed more than adequate to start.
Best batteries ever for the price. Don’t waste your money on those expensive brand name batteries.
No problems using these in my smoke detectors even after sitting on the shelf for a year.
Das Produkt hat meinen Erwartungen entsprochen. ber eine entsprechende Langlebigkeit kann ich keine Aussagen machen.
Fast reliable shipping. Had to replace the battery in my stubborn fire alarm and other brands flaked out quickly but not this one !
Batteries seem to be a good value and thus far no issues.
They work as well as name brand ones but for way less money
Bought for my metal detector battery lasts about an hour, for real I’d buy for fire alarm but nothing else. Just fyi
Don’t hesitate. The prices are fair and the batteries are as good as any of the top brands out there.
These batteries have a great price point. The first battery works well but I can’t measure actual life as it is in the early stages of operation.
Vier Batterien 9 Volt. Lieferung okay. Wie lange sie halten muss ich zeigen, sind im Rauchmelder verbau
I put them in the old and new smoke detectors they work great. It’s been 1 month so let’s hope they las
I just received these batteries a week ago. Each one comes individually wrapped in plastic. I installed one in my single 9V battery multimeter and it works good so far.
However, it’s gonna take weeks to find out how long it will last.
In all honesty I can’t speak for the longevity of these batteries because I haven’t used them long enough to pass judgement, however, I can speak for what my eyes tell me about probability. Let me start by saying these are the finest packaged and protected 9 Volt batteries I have ever seen and I’ve been around nearly eight decades. These batteries come individually sealed in a very sturdy cardboard box, no flimsy cardboard or plastic container. These batteries are packaged far better that either of the two top brands and one of those, Duracell, I have quit buying, due to mediocre performance from all their batteries, including leakage. To sum it up, all my future battery purchases will be ALLMAX, unless there is a performance issue, which I seriously doubt will happen.
I use these in smoke detectors and garage door keypads. I change them in the smoke detectors twice a year. The neat packaging js the best part – No plastic to fight with.
They’re really well packaged and have lasted a few weeks already!
They arrived in perfect condition. I’m using them in smoke alarms so it will be a while until I can review longevity.
They came in fast and work as well as the expensive brands.
I’ve only used two so far so it’s hard to give much more of a rating.
Wrapped great – Individually and collectively. Have good Voltage and seem to be holding plenty of punch after a month’s use . No leakage . Cannot give final response for a few years , but so far – GREAT !
Been using this brand for the past couple of years in our smoke alarms. They last a year, that is all I can ask!
Value for money awesome unsure of longevity at present but I’m sure it’s grea
They’ve lasted as long or longer than the big name brands I’ve used. Less expensive, too.
My annual battery replacement in my smoke/CO alarms throughout the house.
Not yet reached the end of it’s life, so unable to comment on this.
I needed one of these for a complaining smoke detector. They came quickly. The one I put in the smoke detector stopped it complaining. I am happy.
One other plus … The box they came in is perfect. Sturdy, re-closable, and just big enough to store the rest of the batteries. Many other batteries come in packaging that uses up more space than the batteries do, or must be destroyed to be opened. I give these batteries an Extra 1/2 Star just for the box.
Used for for replacing batteries in chairlift controls as I was unable to get to shops.
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.
I use these batteries for a pain-relief tens machine and they are ideal! Long lasting and easy to use.
So this product came charged properly.
I did however knock one star off because it came as 6 years1 month life, not 7 as advertised.
Allmax are as good as the more expensive batteries of the same. Very good value for money and completely reliable.
Been 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.
Batteries were well packaged and fit well into my various appliances. None have run out yet after 2 months
Only used one so far, contact me again in 7 years and I will tell you how they lasted. Used in smoke alarm, fit very well, no problems.
I have a tens machine so I go through a lot of batteries these are great value and las
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.
very good value be careful you dont get order repeated like i did
