How do device batteries work?

Rechargeable batteries are rechargeable batteries for the mobile operation of electrical devices.

Before use, the battery is charged from a power source. It absorbs electrical energy and stores it in the form of chemical energy in the battery cells. The stored energy can then be used as a power supply for the device, even if it is not directly supplied with the mains plug at a socket or a USB connection. The stored energy from the accumulator is available for the mains-independant power supply with electrical energy.

There are two ways to charge device batteries:

In most small devices, the entire device with inserted battery is connected to a power source via a charging cable. The effort required to remove the battery from the battery compartment is eliminated. Examples of this direct charging technology are mobile phones, smartphones and laptops.
The other option is to charge the battery separately on a charger. In this case, the battery must be removed from the device before charging. This principle is often used when using second batteries. While one battery is plugged into the device, the other already hangs on the charging technology. The device is thus completely ready for use, because as soon as a battery is empty, it is exchanged for the newly charged one. Chargers for device batteries can be found here.

What device batteries are available?

The batteries can be divided into four large groups:

Rechargeable batteries for specific devices such as smartphones, laptops, razors and various electrical tools
Power banks and power stations as energy storage and universal charging technology for different battery types
Ups batteries for uninterruptible power supply and emergency lighting
Universal rechargeable batteries in standardized battery formats

This will help you find a suitable rechargeable battery

Important criteria when selecting a suitable battery are:

The size of the battery and the position of the electrical contacts so that it can be inserted into the battery compartment of the device.
The voltage, in volts, that it provides to operate the device.
The capacity in mAh. It provides information on how much electrical energy the battery can provide in a certain period of time. The higher the capacity, the less often the rechargeable battery has to be recharged.

Practical advice

If you have the original battery at hand, all relevant information is usually printed on the energy storage device.

Select a battery for a specific device

Are you looking for a battery for a specific device, either as a second battery or as a replacement for a defective battery? Then proceed as follows:

In the overview, first select the product group. For example, there are device batteries for e-bikes, hand-held scanners, headphones or navigation devices.
On the bottom of the product group, you can then use the filters to:
- Select the type of battery to replace
- Or in the filter to match your device.

Practical advice

The search for a brand is not necessarily a target for rechargeable batteries. Often, device batteries are not manufactured by the manufacturer of the device itself or are worth comparing prices with cheaper suppliers when looking for replacement batteries. Compatibility with the device type alone is important for use.

Use power banks and power stations as external batteries

Power banks and power stations are also rechargeable batteries. However, these are not inserted directly into the device. As external energy storage devices, they supply electrical energy for charging the actual device battery. With this charging technology, the entire device is connected to the power bank or power station with its charging cable. Some power banks allow the simultaneous charging of several device batteries.

Uninterruptible power supply through battery technology

In order to ensure uninterrupted power supply (UPS) , rechargeable batteries take over the power supply if the main power source is temporarily unavailable. For UPS systems there are special batteries of different manufacturers and models in our shop.

In addition, you will find rechargeable batteries for emergency lighting here.

Questions and answers

Where can ich find rechargeable batteries in conventional battery formats?

The majority of the device batteries are special rechargeable batteries. Standard batteries for inserting into battery compartments can be found here.

What was the difference between a battery and a charger?

The battery and its associated charger are usually separate electronic components. It wants the basic principle of battery technology, which aims at mobile use of electrical devices without permanent connection to the stationary power source.

In practical use, the battery functions without the direct connection to the power supply, i.e. without a charger. It then only passes on the energy previously absorbed and stored by the charger to the electronic consumer.

By the way: With some devices the electronics for battery and associated charging technology are installed together. For example, the car battery, which is technically correct, is actually an accumulator that charges itself again while driving using the appropriate charging technology. This principle is also found in the case of electric bikes, the E-Bike. As an alternative to the permanently installed charging technology, these batteries can also be removed and charged at other chargers, as is usually the case with electric wheelchairs, for example.

Search tip: Are you looking for a rechargeable battery that you can insert in a standardized battery compartment instead of a battery? These standardized battery cells for universal use can be found here.
