Best 9 Volt Battery Consumer Reports

Best 9 Volt Battery Consumer Reports, Tips, Reviews, Ratings, and Guides in 2022

If you’re looking for a new 9-volt battery, or just want to know what the best options are for consumers, then you’ve come to the right place. In this article, we’ll be looking at some of the best 9-volt batteries on the market according to Consumer Reports. We’ll also give you a breakdown of what to look for when buying one, and some of the pros and cons of each option. So, without further ado, let’s get started!

What is a 9 Volt Battery?

A 9-volt battery is a small, square shaped battery that produces 1.5 volts, which can often be loaded into certain household items to provide additional power. Typically, they are sold in packs of five or more batteries, and are great for powering things like wireless doorbells, clocks, smoke detectors, medical equipment, toys/models/crafts, radios, speakers, guitar pedals & amps, walkie-talkies, keyless entry remotes or any other device that requires one or multiple batteries to operate it.

Most Common Types of 9-volt battery:

Alkaline: This is currently the most common type of 9-volt battery, and for good reason. Alkaline are reliable, come at a decent price point, and will typically last around 4 hours if used in a smoke detector, or over 40 hours when used with certain types of toys/models/crafts.

Lithium: Lithium batteries are some of the bests you can buy. They’re very expensive though, especially compared to Alkaline, but they offer more power, which results in longer lasting batteries. Another benefit of lithium batteries is that they don’t drain nearly as fast as alkaline do when not being used (up to 90% less). They also have about double the lifespan of alkaline. So, if you’re looking for a high-quality 9-volt battery, then lithiums are the way to go.

Rechargeable NiMH – Like lithium batteries, rechargeable NiMH’s are some of the bests you can buy. They last about twice if Alkaline and provide 1.2 volts per battery instead of 1.5 volts like alkaline do. The only negative thing about these types of batteries is that they tend to lose their charge rather quickly after being used for around 6 months or so (although it should be noted that this does vary from device to device).

What should you know about 9-volt battery?

To get the most life out of each 9-volt battery, you should always take it out as soon as your device stops working. Leaving a battery in a device that’s not being used will cause the battery to drain faster.

If possible, avoid using 9-volt batteries with cheap devices or toys because doing so will result in a very short lifespan.

Another thing to note is that there are two different sizes 9-volt batteries currently on the market: Size 10 and size 13. These numbers refer to how many millimeters thick the plastic casing around the battery is. Now, if you have a device that requires one of these sizes then you might want to consider buying an adapter, since they’re typically cheaper than buying an entirely new 9-volt battery.

If you buy a 9-volt rechargeable battery, you’ll have to charge it before using it the first time. Just follow the instructions that come with your battery.

Factors to Consider before buying 9-volt battery:

What to look for when buying 9 Volt Batteries?

Price Range: As expected, price tends to vary depending on what type of battery you want to buy. If you’re only going to be using it for a few small devices, then alkaline batteries are generally going to be cheaper. However, if you need a long lasting 9-volt battery that will power a lot of items over a long period of time, then lithium or rechargeable NiMH’s will probably suit your needs better.

Number of Batteries: Most 9-volt packs come in 5-packs, although there are options available with 2-batteries and 10-batteries included as well. Obviously, the more batteries contained within the pack, the less often you’ll have to replace them. So, if you have a lot of devices that require 9-volt batteries, then it may be worth the extra few dollars to buy one that contains more.

Longevity: As with any type of battery, longevity is very important when buying 9-volt batteries. If you will only use them occasionally, then alkalines are probably your best bet in this case. However, if they’re going to be powering larger devices for an extended period (like smoke detectors or toys), then consider getting lithiums or rechargeable NiMH’s instead.

Noise: Noise is another factor that can determine which type of 9-volt battery you should get. If you need something quiet, then Alkalines, Lithiums , or Rechargeable NiMH’s are your best options due to their lack of noise .

Warranty: Just like all other products that you buy, 9-volt batteries will also have warranty information included with their packaging. If something were to go wrong with your battery, then be sure to check out any warranty information that’s included in the box to see if it can be replaced or refunded.

If you take care of your devices and put your 9-volt batteries through normal use, then buying high quality 9-volt batteries will give you great results. However, if you happen to do something with them that goes against their intended use (for example, not removing 9-volt batteries from high-drain devices when they need to be replaced), then the warranty information on the box may help either refund or replace your battery.

Size:  Both size 10 and size 13 are the most common sizes of 9-volt batteries, but you might need to buy an adapter if your device needs one of these sizes.

Quality:   Since these batteries are usually the cheapest available, you get what you pay for. They’re not going to last long or have a lot of power, but if you just want something simple that’s only going to be used a couple times , then alkaline 9 volt batteries will work fine .

 

Power output: Since alkaline 9-volt batteries are designed to hold their power for long periods of time, they’re able to provide just as much current as any other battery.

Ease of replacement:   Just like all other sizes of batteries, the easiest way to replace them is by using a screwdriver to open your device and taking out the old one. Afterwards, simply insert your new 9-volt battery into the empty slot and use two screws to secure it in place so that it doesn’t rattle around or break.

Usage: When it comes down to it, alkaline 9-volt batteries are usually used for lower current devices (like smoke detectors or toys) that aren’t going to be heavily used.

Durability: Like all other sizes of 9-volt batteries, alkalines are very durable and unlikely to break if their intended use is followed properly. However, if you do happen to drop or puncture them, then they may shatter and leak, which will damage your device.

Length: Alkaline 9-volt batteries are the longest of all 9-volt batteries (as well as the biggest), which is another reason why they’re not ideal for use in higher current devices.

The Pros and Cons of 9-volt battery:

Pros:

9-volt batteries are usually very cheap, so if you only have a couple devices that need them, then you won’t have to spend too much

9-volt batteries hold their power nicely, so they’re great for devices that aren’t going to be used often

Cons:

If your device needs more power, then alkaline 9-volt batteries are not ideal for its use since they can’t provide as much current as other types of battery.

What happens if I put a different type of battery into my device?

You should never place a different kind of battery or metal object inside of your device unless you have done extensive research on whether it’s safe to do so. Putting in a foreign object can cause damage to the battery’s connector, which could impact your device’s performance.

What are some alternative things I can use instead of 9-volt batteries?

You can try using D cells with your device if it is compatible with them. If not, then you might consider switching to rechargeable lithium ion or nickel-metal hydride (NiMH) 9-volt batteries since they tend to provide more power than alkaline ones.

What are the best rechargeable batteries to use with my device?

In general, it’s advised that you use either nickel-metal hydride (NiMH) or lithium ion 9-volt batteries if you want your device to perform at its peak. These types of batteries can provide up to 10 times more power than alkaline ones. However, make sure that your device is compatible with these before using them since they both have their own special standards and requirements.

Which 9-volt battery lasts longer? Alkaline or Lithium ion?

It’s difficult to determine which type of 9-volt battery lasts longer since it really depends on the brand. Lithium-ion ones usually provide more power than alkaline batteries, but they can be more expensive to purchase. This means that in some cases, it might work out cheaper for you to stick with alkaline 9-volt batteries instead of lithium-ion ones.

How good are midget batteries?

Midget or AAA Alkaline Batteries generally do not last long when used with devices that drain a lot of energy. If this is your main use for them, then you will find yourself having to replace them quite often unless you have money to burn. Repeatedly replacing alkaline midget batteries can get costly when compared to other batteries such as lithium-ion ones.

What’s the best 9-volt battery?

The 9-volt battery that is best for one person might not necessarily be the best choice for someone else. Therefore, it’s important to look at your specific needs and choose accordingly instead of blindly following what someone else has done or something you’ve seen online.

Do lithium-ion batteries explode?  Do they leak acid?

Lithium-ion batteries can explode if they are placed under a lot of heat, but this doesn’t happen right away since there is a period where the heat accumulates until it reaches a point where it combusts or explodes. Furthermore, lithium-ion batteries do not contain any acid inside them, so they cannot leak out from normal use unless you purposely puncture them somehow. 

Can I leave my batteries in the charger overnight?

If you are using a smart or digital charger, then it’s generally not advised that you leave your batteries inside of it for too long. Leaving them in the charger all night can cause them to overheat which could end up causing damage to both the battery and the charger itself.

What type of batteries should I use with my TV remote?

It’s best for you to use alkaline or lithium-ion batteries with your TV remote since they last longer than other types but be willing to keep some spares on standby because these will eventually run out. You can also try switching it up by alternating between alkaline and lithium-ion batteries so that each one gets an equal amount of use.

How do I fix my remote control not working?

If your remote isn’t working, then it’s possible that its batteries are dead or dying. You can also try cleaning the receiver where you put in the batteries or using some rubbing alcohol on it since dirt and debris can sometimes interfere with how well it works. If none of this is helping, then you might need to buy new alkaline batteries for your remote instead.

How does a 9 Volt battery work with LED flashlights?

A 9 Volt battery can work with a LED flashlight, but it will drain faster than alkaline batteries since they provide more power. This means that you will need to ensure that your 9-volt batteries are fully charged or have been recently replaced before heading out. In the long term, it might be better for you to buy lithium-ion batteries instead if you want prolonged use of your flashlight before needing to replace them.

Which 9V battery is best for my smoke detector?

If you need new batteries for your smoke detector, then using either nickel-metal hydride (NiMH ) or lithium ion ones is recommended . These types of batteries can last a lot longer than alkaline ones and do not contain any harmful mercury inside them so there is no risk of them contaminating the air in your home.

How does a 9-volt battery work with a doorbell?

9 Volt batteries will work with a doorbell, but they often do not last very long since they drain quickly. You might have better luck using alkaline or lithium-ion batteries with your doorbell instead if you want to ensure that it works smoothly throughout the day. What’s more is that some people have found it helpful to use different brands of batteries for their doorbell so they can tell whether it is the battery itself or something else going on when there are issues.

What do rechargeable NiMH batteries give out when they die?

It’s important to know that all rechargeable batteries will eventually die and give out zero volts. Therefore, even the greenest of consumers should consider recycling them instead of throwing them away. Even though they aren’t going to be reliable anymore, you can rest assured that they have been put back into use as an alternative energy source somewhere else.

What is the average life of a 9 Volt battery?

It’s estimated that a 9 Volt battery can last up to 100 hours since it is one of the most powerful varieties available. This means that if you use your 9-volt batteries sparingly, then they should last quite a long time before needing to be replaced.

How do I charge my rechargeable batteries?

You will need to place your rechargeable batteries inside of a charging station with their poles pointing in opposite directions, so they don’t overheat and explode. Once they have been recharged sufficiently, turn off the station and remove them from inside of it so you can put them back into whatever device you originally used them with.

Do 9-volt batteries have mercury?

Lithium-ion batteries contain no mercury so they are safer for people to use. All other types of rechargeable batteries may have trace amounts inside of them but there won’t be enough for you to feel any negative effects. Mercury is a naturally occurring chemical, but you should still try to recycle your batteries whenever possible to keep it from going into landfills or being released into the environment.
