Batteries

Electrical devices need energy and thus a power source to function properly. There are many possibilities of supplying it, among them batteries, which is the simplest way to power a device. This of course applies to mobile and portable devices, which we use not always where we have access to the socket and mains power. Batteries can be found both in the remote control for TV, as well as in children's toys and remote-controlled vehicles, as well as electronic devices and controls for larger and more complex systems. Batteries differ not only in appearance but also in parameters. Not every battery fits all electronic devices. Therefore, it has to be properly adjusted to the requirements of the device. We have a choice of, among others, commonly known fingers, lozenges, i.e. flat batteries used most often in watches, as well as batteries for special purposes, e.g. for smart watches and smartphones.
