Block Batteries

About 9V Batteries

Even if you are playing with a remote-control car, playing an electric guitar, you are relying on 9V batteries to power them. Several other household devices like smoke detectors, flashlights, wall clocks, and milk frothers also depend on them for power. These are special types of batteries, normally called block batteries.

In today’s world with electronic gadgets everywhere, 9V batteries are also ubiquitous. It is, in fact, the most popular type of battery in the world. One reason for this is because they have become the industry standard for a slew of different electronic devices, starting from the earliest transistor radios in the 1950s. Furthermore, you can easily tell a 9 V battery apart from the others because of its unique shape. It looks like a rectangular prism with a polarized connector at one end. Read this article to find out more about them. Having a better understanding of them will help you choose the right model of block batteries for your use.

Four best 9V batteries to buy

The history of 9V batteries is as old as the history of transistor radios. Both of them were first made in the 1950s. Original 9V batteries were first made with mercury oxide. Mercury oxide batteries were, however, not efficient by today’s standard. Luckily, battery tech has improved by leaps and bounds in the last decades. Hence, the block batteries. Modern batteries use compounds like nickel-metal hydride, nickel-cadmium, and lithium-ion. This prevents them from losing their charge capacity over time and ensures a consistent power output. Here is a list of four of the best nine-volt batteries on the market right now!

EBL 9V five-pack batteries

This charger-battery combo comes with five 9 V batteries and a charging station that supports charging all five of them at the same. But in order to charge them, you don’t necessarily have to plug in all five batteries. EBL has been manufacturing batteries for more than 20 years. So, they have mastered their techniques. As a result, this battery pack has exceptional durability and performance. These batteries are an excellent choice for smoke alarms, toys, clocks, and even medical devices. Nickel-metal hydride used batteries in these batteries are not quite as energy-dense as lithium-ion batteries. But compared to all the other cheaper batteries you can find; these have more charge capacity of the block batteries.

LP 9V Rechargeable Battery Pack

If you are looking for a pack of rechargeable batteries, this battery/charger combo is an excellent option. This pack includes two 9 V rechargeable lithium-ion batteries and a charger. Lithium-ion rechargeable batteries are an ideal option and are most commonly used for portable electronics, like mobile phones and cameras. They provide high-density energy and excellent power performance. If you keep a fully charged LP rechargeable battery idle, it will only lose two per cent of the charge over a period of two months.

Tenergy 9V Rechargeable Battery

The batteries for Tenergy are also nickel-metal hydride. This package comes with four 9V batteries, each suitable for a variety of uses. You can use them in smoke detectors, walkie-talkies, and even medical devices. The most attractive feature of this battery is its incredibly high charge density. Furthermore, because the battery has a built-in charging IC, it prevents the negative effects of overcharging. This also means that there is no harm if you use a third-party charger to recharge these batteries. However, it is recommended that you use the original charger that comes with the battery.

Energizer 9V Lithium Batteries

Energizer is probably one of the most famous brands among battery manufacturers. Moreover, Energizer Advanced Lithium 9V batteries are well known in the industry for their reliability. The expected life of this lithium battery is up to 10 years. Also, lithium batteries can hold twice as much charge as alkaline batteries. They are leak-proof and perform well even at high temperatures. Higher power output means you can rely on them to run small computers, home appliances, smoke alarms, and electronic gadgets.

Tips on how to buy 9V Batteries Online

Finding the right type of battery might not feel like a difficult thing to do at first. However, because there are a variety of different batteries, even in the 9V category, it is not that simple. While it is true that a device might run if you put enough 9V block batteries in it, choosing a random 9V cell will not give you the best performance. You should know what factors to consider while selecting the batteries. Here are a few things to keep in mind while shopping for them.

  • Rechargeable vs Non-rechargeable – Two main categories in batteries are rechargeable and non-rechargeable. Rechargeable ones can be reused hundreds or thousands of times before they start to lose their ability to hold the charge. On the other hand, non-rechargeable batteries are single-use batteries. Buying rechargeable batteries makes sense if you are using devices that run out of batteries quite fast.
  • Charge capacity – This refers to how much charge the battery can hold. This varies wildly depending on the chemical composition of the battery. One thing to keep in mind is that although 9V batteries have a larger form factor, they actually hold less charge than an AA battery.
  • Type of battery – There are at least half a dozen different types of batteries, even within 9V batteries. The most common one is the standard Nickel-metal hydride batteries (NiMH). NiMH batteries are suitable for high power devices like cameras and GPS devices. Another type is the Lithium-Ion battery. Li-ion batteries can hold more charge than NiMH batteries. Therefore, they are useful for laptops and smartphones.
  • Safety – This one is true for all kinds of electrical and electronic devices. Batteries are basically a container for electric charges made of chemical materials. If the battery is not well built, that creates a potential for many hazards. So, always buy a battery from reputed brands.

All of us these days own and use at least some kind of electronic device. Therefore, you will need many other products as well like battery chargers, tablets, smartphones, cameras and camera supplies, lights, memory cards, and more.

Question & Answer

How long will a 9V battery last?

It is not possible to answer this question without going into concepts like power input of devices, the difference in charge capacity between different battery types, and so on. In short, there are two factors that dictates how long a battery is going to last: how much charge the battery can hold and how fast the device is draining the charge from the battery. That means, you will have to calculate this separately for each scenario. Look at the input power rating of the device and the charge capacity of the battery. Then do the math.

Which 9V rechargeable battery is the best?

There is no one type of 9V battery that is ideal for all kinds of uses. Rather depends on how much current the device requires to operate. Also, it is not always economical to buy rechargeable batteries in all use cases. Because rechargeable batteries cost many times more than non-rechargeable ones, it only makes sense to buy them if you need to replace the block batteries every now and then, for example in the case of a camera. On the other hand, if you need a battery to run a clock, it is going to be cheaper to use a non-rechargeable battery.
