Battery "Crohn": what it is and what it is for

Every person in the house has a device,which runs on batteries. For example, the remote from the TV, children's toy, a tonometer or any other electronics. We often do not think about what kinds of batteries are there. Just come to the store and buy exactly the battery that we need for our device, in accordance with the instructions. In fact, the battery market offers a wide selection. There are batteries type AA, AAA, C, D. But there is also a special kind - this is the "Crohn" battery, which has the type PP3. And this is not the whole list of different batteries that have the greatest consumer demand.

In appearance, mini-batteries differ from each other only in size. They all have a cylindrical shape, except for one type (the "Crohn" battery is a parallelepiped).

Separation of batteries occurs also on the electrochemical system:

1. The salt battery is differentfragility. Work in high-tech devices for such batteries is impossible (20 minutes - a record time of its use). The maximum that her work is designed for is a quartz watch or another simple and small device.
2. Alkaline batteries have great performance. AT High-tech devices can work for two or three hours.
3. The lithium battery broke all records according to the working time. It has been running for over a month, even in the most powerful devices for energy consumption (even with the device constantly on).

Recently, more and more popularityacquire battery cells. They have different charges and are capable of working for a longer period, unlike conventional batteries. But the main feature of batteries is their ability to restore their charge with a charger. Such "charging", as a rule, are sold for a certain type of rechargeable batteries. However, recently, universal devices for recharging batteries have started to appear on the market more and more often (any type, including the "Krone" battery) can be charged.

Batteries of different shapes are designed for different devices. Batteries types AA and AAA are often used in remote consoles, small flashlights,

medical equipment and digital technology. Devices of types C and D are used for large lamps and devices of a technical nature. In children's toys are often used batteries "Crohn".

These power supply elements are also differentby type and electrochemical system of batteries, respectively, their cost depends on these factors. The most expensive are battery batteries (the "Krona" battery is also rechargeable). Salt is the lowest cost, and alkali is sold at an average price.

Recently, manufacturers of technicaldevices are increasingly producing products that use a battery "Krona", the price of which is small, and the charge keeps quite a long time. This is beneficial to the manufacturer and the buyer.
