I thought it would be a no-brainer to pick a 9-Volt battery, as our smoke detector battery was dead and I hit the market to find a pack of a 9-volt battery.
But, when a salesman asked me which brand 9-Volt batter do you want? I had no clue.
He further asked, do you want a rechargeable 9-volt battery or a disposable battery? Me, with the same confused face.
And the next question made me fly off and do some research.
Let me rephrase the question again, maybe you too are like me, and just want to buy any 9-volt battery with zero research.
“Do you want an alkaline battery or a Lithium-Ion battery?”
We all use 9-volt batteries in our homes. They are mostly used in small electronics devices along with Smoke detectors, transition radios, carbon mono oxide detectors, and many more.
So, it is always a better idea to have a pack of batteries ready before they run off power and you forget even to replace the batteries.
The research I am putting on is based on my testing and experience. I narrowed down around 2 dozen best 9-volt batteries and picked the mentioned ones.
These 9 Volt batteries are what I found most useful, for me. I am sure this guide will be a great help for you too.

Consumer Reports 9 Volt Battery Buying Guide
The battery is an individual that plays an important part in the overall cost of home devices. To get the most out of that battery, you should pick the one that suits your devices and your overall needs.
But, what factors should you pay special attention to?
Like, for a novice or who hardly pays attention when buying batteries, what should be the factor you should ensure your batteries come integrated with?
This tiny section is going to help you.
Lithium or Alkaline
Lithium batteries come with high capacity, higher initial voltage, and longer shelf-life. They got more power of storing energy than alkaline batteries. They are mostly used in high-drain devices, where you don’t have to worry about the battery draining quickly.
On the other hand, alkaline batteries are used for low-drain devices like LED Headlamps, Toys, Clocks, LED Flashlights, radios, and many more. They can be used in high-drain applications like video cameras, incandescent bulbs, and others.
But for the type of devices like fire alarms, smoke alarms, and others Lithium batteries are considered the best because of their slow self-discharge. For that, they are considered ideal items for devices that are not used as frequently.
But, Lithium batteries are more expensive than alkaline batteries.
For average household items which are used every day on regular basis, we prefer using alkaline batteries.
Dischargeable or disposable
Disposable batteries aka single-use batteries are designed to be used until they are left with no power. Depending on their size, shape, and type, a single-use battery can last for around 7-15 years on the shelf.
On the other hand, rechargeable batteries can be recharged for repeated use. They are more expensive than single-use batteries and can cost around $15-$40 for a pack. If you want to buy rechargeable batteries for regular use devices like digital radios, DSLR cameras, and many others, it is the best idea to buy a rechargeable battery.
Your need for the device
Now, you have seen how rechargeable and disposable batteries differ in size and performance. Now it comes down to your device, and the type of battery you need to power your device. If you have a low-drain device, any battery can do that. If you need to power a high-drain device, this is where you need to think twice before giving it a shot.
Generally, lithium batteries compared to alkaline batteries are considered as I mentioned above too for high-drain devices. If you buy a rechargeable lithium battery for your device, look for high capacity. Because higher capacity will have more power or battery stored, that will last longer on a single charge.
Shelf life means how long the batteries can hold the power. Like, alkaline batteries can hold the power for around 5-7 years, and lithium batteries for 10-15 years on the shelf.
Rechargeable batteries lose their power faster than disposable ones. But the newer low self-discharge rechargeable batteries like lithium-ion batteries hold the power for longer compared to traditional rechargeable batteries.
Battery life means for how long in one charge or one life the battery can juice up your device. For rechargeable batteries, you need to consider how long the battery last on one charge, and single-use, for how long the battery can run.
Number of Batteries
That’s one of the most important questions because I always recommend having stock ready for most important devices like smoke alarms.
Do a quick survey around your home, check how many gadgets you have for 9v batteries, and purchase as per your needs.
Purchase more than what you need, so that you always have a few spare on your hand.
With lots of brands and models available right now for 9V batteries, we have gathered the top best 9V batteries here. In the list, we added alkaline as well as lithium-ion batteries, rechargeable as well as one-time-use batteries.
These 9 Volt batteries can be used for multiple applications and electronic devices. Now, it is you who suits your expectations, and your budget range.
We can hope that this guide will help you pick the right option. And if you are buying it for the first time, the buying guide section is surely going to help you a lot.
How Long Does a 9V Battery Last?
There is more than one thing that takes part in the overall life span of a 9V battery. Like, its type, the alkaline battery shelf life is around 5-10 years, and lithium battery shelf life is a bit longer around 10-15 years.
It also depends on the quality of the battery, and the load you are putting it under.
What Is The 9V Battery Used For?
9V batteries can be used for a wide range of applications. Like, a 9V battery is used in smoke alarm devices, radios, walkie-talkies, fire alarms, portable electronics, and much other use.
