Batteries

In this category, you will find a large selection of batteries. We have both regular batteries, rechargeable batteries, battery chargers, and special batteries.

Additionally, we also have a large selection of many other exciting items, such as MP3 players, strips, and powerbanks.

How does a battery work?

Batteries are something that most people use in their daily lives, but to a lesser extent than before.

In the past, most people used the type of battery you find on this page for almost all devices, at least if they were wireless.

Today, we still use batteries for most wireless devices; however, they have become built-in and are increasingly rechargeable, unlike the batteries of the past.

The science behind batteries

To make it a little technical yet still simple, we quickly go over the technology and the science behind the batteries we use.

Overall, a battery is an energy source that converts chemical substances into usable electrical energy.

Batteries contain acid, which is used to create energy, but is incredibly harmful to the environment.

This is why batteries are constructed in an incredibly strong way, to keep these substances contained.

This is also the reason why batteries cannot be disposed of with the rest of our waste but must be separated, as it harms the environment if the substances escape the battery's casing.

Lithium batteries

The type of battery that almost everyone buys and uses is called a “lithium battery.”

Lithium is the name of the metal the battery is made from.

Lithium is a so-called “alkali metal” that is incredibly strongly reducing and very light. This makes it perfect for batteries.

Like all other batteries, modern lithium batteries are constructed with a positive and negative side, which must be inserted correctly into your device to provide power.

5 things to look for when buying batteries

When looking for new batteries, there are a few things to keep in mind, as there are many different types of batteries.

Some batteries last longer than others, depending on the type of battery it is and sometimes also which manufacturer it is from.

Below are a few points that you should consider before purchasing your next batteries.

#1 Battery size

When buying batteries, size is the most important thing to consider, as there are many different battery sizes, and not all can be used for your devices.

Some sizes are extremely similar to each other, and it can be difficult for some to distinguish between them.

AAA batteries and AA batteries are often the two sizes that people tend to confuse. AAA batteries are used for newer remote controls for televisions, while AA was the earlier standard for remotes.

#2 Rechargeable or non-rechargeable batteries

If you plan to use your devices over a longer period, it makes sense to invest in rechargeable batteries instead of disposable batteries.

With rechargeable batteries, you do not need to buy new batteries every time they run out of power.

You just need to plug them in to charge, and they will be ready to use again in a few hours. This way, you also save money on having to buy new batteries each time.

With rechargeable batteries, you not only save money but also space, as you do not need to have used batteries lying in a bag or box until they are disposed of at the landfill.

#3 Lithium batteries

Lithium batteries have a much better energy density than regular batteries and are therefore better for electronic devices that are used for extended periods.

More and more technologies have begun to use lithium batteries, and it is therefore also the universal standard for batteries today.

These electronic devices use lithium batteries:

• Smartphones
• Tablets
• Laptops
• Digital cameras
• Electric cars

#4 Bulk discount

Often, batteries are sold in slightly larger quantities, such as in a pack of 12, 24, or 60. If you know you will need the batteries again sooner or later, it can be worthwhile to buy in larger quantities than just a few.

You often save a little money by buying the larger packs than by just buying a pack with, for example, four batteries.

On this page, you can buy different battery packs ranging from 2 batteries to 60 batteries in a pack.

#5 Longevity and Max number of charges

The best batteries can usually last up to 5 years and be recharged about 400 times before it's time to replace them with new batteries.

Even though the batteries are rechargeable, they still have a max. lifespan. Not all batteries can last equally long and for the same duration.

Therefore, it is important to read up on how many times they can be recharged and how many years they last.

This is primarily what differentiates the cheaper batteries from the more expensive batteries from larger manufacturers.

Frequently asked questions about batteries

Can lithium batteries be recharged?

Lithium batteries can indeed be recharged, just like regular batteries can. They have a better energy density than normal batteries, which means they are also better at holding charge, making them perfect as rechargeable batteries for electronic devices.

Are lithium batteries dangerous?

Lithium batteries are not dangerous as they are designed to contain the chemicals inside the battery well. The chemicals in the battery can, however, become dangerous if they come into contact with too much heat and explode.

How long can batteries last?

Most batteries can last between 3 - 5 years depending on the size and manufacturer. The older the battery is, the less it can last in the future.
