They are larger than other 9V batteries
Reviewed in the United States on January 23, 2018
First and foremost, we really like the Amazon brand batteries. I used these batteries in a digital clock and worked just fine. However, our main reason for buying this set was to use them in our smoke detectors. In short, they are TOO BIG! I never realized 9V batteries vary in size until we tried to use these in the smoke detectors. Please see the pictures. They are slightly taller and a little wider. The door on our smoke detectors simply won't close and you don't want to force it. This is the only reason we purchased this many...so learning has occurred! We simply don't use them for anything else other than the occasional battery in a digital clock and for that they work fine. Please keep this in mind when purchasing. Make sure whatever you are putting them into that you have the extra length and width to accommodate a slightly larger battery.

The positive and negative charges on one of the batteries in the set was labeled in reverse. I installed the battery based on the charge and within a few seconds the battery was making sizzling noises and smoking. I turned off the device and carefully opened the battery compartment. Upon comparing it to the other batteries I realized it had been mislabeled. I'm thankful I was still in the room when this happened considering one of the devices I'd installed the other 9V battery in was in a different room. I will be contacting Amazon and filing a complaint. I'm very disappointed in their quality control standards.

I've also had the same problem as a bass player who reviewed these batteries. The battery is too tall and fat for tight battery cavities and don't last long enough. You can see from my attached ***PHOTOS*** that it doesn't even fit in my battery compartment w/o smashing it in and you don't want to do that because it'll bite into the attached wiring.
There are more cons for this particular usage than there are positives. They may work great in other applications but I'm going back to buying regular brand batteries for my electronic instrument needs.

Not so good for active electronics in instruments/pedals
Reviewed in the United States on February 19, 2018
I thought these would be a great deal since I have quite a few pedals and active basses that need 9v batteries. Also seeing the amount of star ratings thought I couldn't go wrong. But these things can't seem to keep a charge even when I unplug everything.Reviewed in the United States on February 19, 2018

FYI, this review is for the 9 volt batteries. Amazon apparently groups the reviews for all of their battery styles together. I can't really help with that.
Batteries were just a tiny bit longer than the ones they were replacing. This was a problem in my carbon monoxide detector... But the battery compartment is finicky to battery size. I imagine this would work fine in most places, so long as the battery compartment isn't too fancy.
By my measurements, the AmazonBasics battery is the same size as another heavy duty battery that won't fit in my CO detector. These batteries are 0.6mm longer and 0.6mm wider than a standard duracell battery.
My photos attached show some measurements... Which may not be perfect but hey I don't get paid for this:
1: The length measurement of an Amazon Basics battery (47.96mm), along side a Duracell (clearly shorter) and another brand "Heavy Duty" battery.
2: A measurement of the difference in thickness between the Amazon Basics and the Duracell battery. (0.59mm thicker)
3: A measurement of the difference in length between the Amazon Basics and the Duracell battery. (0.6mm longer)

Before purchasing these batteries I thought All 9V batteries were identical ... Now I know they're not.

For the most part these AmazonBasics 9 Volt Batteries work great and for the price are an excellent value but there not for everyone and should be used and purchased with caution.
The main problem with these AmazonBasics 9V batteries is they are Slightly Larger than most other 9V batteries and the battery posts or terminals on the top of the AmazonBasics 9V are slightly shorter or protrude less than other name brand 9 volt batteries.
The AmazonBasics 9V batteries work well in my multimeter, wireless motion sensor, tone probe and tone generator however they don't fit or work with my wireless microphone, mixer, guitar tuner or CO2 detector.
I was intrigued by the slight difference in size between regular 9V batteries and the AmazonBasics brand so I took out my callipers and measured an AmazonBasics 9V and a Duracell 9V and here are the results
Length: 0.59mm Longer
When measuring the length of the battery from the top of the positive terminal to the bottom of the battery the AmazonBasics 9V battery is 0.59mm longer than a 9V Duracell battery.
Thickness: 0.53mm Thicker
When measuring the thickness the AmazonBasics battery was 0.53mm thicker than a 9V Duracell battery.
Terminal Height: 0.45mm Lower
When measuring the height or protrusion of the terminals on the AmazonBasics 9V battery compared to the Duracell it was visually evident that the terminals on the AmazonBasics 9V are lower and when measuring with callipers it turns out they indeed protrude out 0.45mm less than a 9V Duracell battery.
After measuring the two batteries I now understand why the AmazonBasics 9V batteries will not work in some of my devices. The AmazonBasics 9V battery is too big to fit into the housing of my CO2 detector and guitar tuner.
While the AmazonBasics 9V battery fits into the compartment of my cordless mic and microphone mixer the terminal posts are too short to make contact and therefore won't power up these devices.
So What's the Verdict? There's no denying these AmazonBasics Batteries are a fantastic deal and if you're a Prime Member you get an additional 20% off bringing the cost per battery down to $1.37 each, compared to $3.24 each for Duracell 9V's.
For my uses, I find the AmazonBasics batteries last about 70% as long as the Duracell's so when your factor in price and performance the AmazonBasics 9 Volts are a good value as long as they will fit and work in your device ... and that my friends is the magic question.
The bottom line - I will continue to purchase and use AmazonBasics 9V batteries for the devices they will work in and
Unfortunately I will still have to use the more costly name brand batteries for the devices they won't fit.
