Batteries & Rechargeable Batteries – Mobile Power Supply for Electronics Projects
Batteries and rechargeable batteries are essential components for the mobile power supply of microcontrollers, sensors, development boards, and many other electronic devices. Whenever no fixed power source is available, they provide the required electrical energy.
Technically, a distinction is made between batteries as primary cells, which are generally non-rechargeable, and rechargeable batteries as secondary cells, which can be charged and discharged multiple times. Both variants store energy chemically and provide it as electrical voltage when needed.
In the field of embedded systems, IoT, robotics, or mobile measurement and control applications, choosing the right energy source is crucial. Factors such as voltage, capacity, form factor, and discharge current determine which battery or rechargeable battery is suitable for your project.
Batteries – Reliable Primary Cells for Many Applications
The most common battery types include alkaline batteries, zinc-carbon batteries, lithium batteries, and coin cells. They differ in chemical composition, capacity, voltage characteristics, and area of application.
AA batteries (Mignon, LR6) and AAA batteries (Micro, LR03) are frequently used in remote controls, flashlights, wireless mice, or sensor projects. Typical capacities range between approximately 1.9 Ah and 2.5 Ah for AA, and between 0.5 Ah and 1.2 Ah for AAA. Proven products are available from manufacturers such as Panasonic, Duracell, VARTA, and tecxus.
9-volt block batteries are used when higher voltage is required at comparatively low power, for example in smoke detectors or measuring devices. Lithium batteries offer high energy density and long shelf life, while coin cells serve as compact voltage sources in watches, calculators, or backup circuits.
Many models are available not only in single blister packs but also in practical packs of 10 or 24. This simplifies stocking for workshops, laboratories, industrial applications, or regular use in electronic devices.
Rechargeable Batteries – Reusable Energy Sources for Sustainable Power Supply
Rechargeable batteries are reusable energy storage devices and are particularly suitable for equipment with regular energy requirements. Typical variants include NiMH standard rechargeable batteries, lithium-ion rechargeable batteries, industrial batteries, device-specific batteries, as well as high-performance power banks for USB-powered electronics.
Lithium-ion rechargeable batteries are characterized by high energy density and low self-discharge. They are used in microcontroller projects, mobile computers, cameras, or embedded systems, among others. Selection is based on voltage, form factor, and capacity in mAh.
Power banks combine integrated lithium cells with charging electronics and protection circuits. They enable the mobile power supply of development boards, single-board computers, or smartphones via USB.
Lead-acid batteries also play a role in electronics and industrial applications. They are robust, cost-efficient, and easy to charge. Typical areas of application include alarm systems, emergency power systems, telecommunications, or photovoltaic applications.
Accessories for Batteries & Rechargeable Batteries
Suitable battery holders, battery clips, battery testers, and transport boxes are available for safe and flexible use. Battery holders allow the easy integration of AA, AAA, or 18650 cells into prototypes and enclosures.
Battery testers help check the charge level and identify faulty cells at an early stage. Clips and connection cables make it easier to connect 9V blocks or individual cells to development boards. Transport boxes protect batteries and rechargeable batteries from short circuits and mechanical damage.
Especially in prototyping, maker projects, and industrial applications, the right accessories contribute significantly to safe and reliable power supply.
