Why are there no B batteries?

Batteries are the lifeblood of modern technology.

They power everything from your TV remote to a hybrid car and to a laptop computer, and they're becoming more important as the world becomes increasingly electrified.

The types of batteries commonly used in everyday life are AA, AAA, C, and D batteries. Did you realize that there are no "B" batteries?

What happened to the B battery? Is it a lost battery technology?

In this article, we will discuss and have a look at why are there no B batteries, and we'll also take a look into some other common battery-related questions.

Are there B batteries?

B batteries do exist, but they are a lot less common than A, AA, AAA, C, and D batteries. 

You may never have seen a B battery in your life, and that is because they were left behind when the naming system for batteries standardized their designations.

When the first vacuum cleaners were invented, they required a lot of power. And so, in order to generate enough juice for these devices, companies manufactured large batteries that could fit inside and provide long-lasting energy through high voltage currents. These "B" sized batteries operated with voltages ranging from 6V up to 12Volts while others used 'A' size battery cells at 3 volts each or less, thus creating smaller AA (1 cell) AAA (2 cells), C(4cells) D(6+cells). As time went on, however, and technology advanced, their practical use diminished significantly as we moved away from vacuumed floors into more convenient handheld vacuums that need far less power than before, hence making them largely old and no longer in use.

You may be wondering why a B battery isn't sold or available in stores nowadays. The answer to this question lies in how the commercial success of certain brands has changed over time. In general, people use only four types of these: AA-sized ones being most popular as well as AAs' smaller cousins - AAA; then come to Cs and Ds. Nowadays, manufacturers continue making products using those trusted old staples due to availability but also because not many consumers have other choices available at stores or elsewhere online.

Why do we never see B batteries?

You might be wondering why we never see B batteries. 

Batteries have been around for a very long time. In fact, the word battery comes from an 18th-century term for containers that held a mixture of powder and shot. The word was casually used to refer to an electrical device composed of two electrochemical cells that produce direct current. Nowadays, batteries are incredibly common in many aspects of society. However, not all batteries are created equally.

You probably won't find any B batteries at your local hardware or Walmart, but that does not mean they are totally extinct. You just might need to search a little harder for them and buy them from an online retailer, or most B batteries are labeled differently. However, when you buy a pack of AAA, it is labeled as "Battery". But this does not mean B batteries do not exist.

B-size batteries are often used as cells to make up larger batteries. For example, a particular purpose 6-volt battery might be made with 4 B size cells inside that create 1.5 volts each for the total of 6 volts. The Energizer U10 is close to a B-Size and likely will work if you need it.


There were B batteries, but they're not as common as other battery types. There have been a variety of battery types throughout history, many different sizes, shapes, voltages, storage capacities, and with all sorts of different names.

B batteries were no longer around by the time the smaller, more common battery types came about. Different sizes were reduced in their voltage and stored capacity over time as technology advanced. This is why we no longer see B batteries. With so many changes with the devices and gadgets we used in today's world, B batteries started to fade because of the increased use of electricity. B batteries were used in products like antique radios, which aren't being sold as frequently and weren't as popular back then.

The different sizes/shapes/voltages/storage capacities of batteries have all been standardized so that they can be interchanged between devices today.
