Battery charger: feature and functionality

To date, the field of application of AA and AAA batteries is quite extensive. Such batteries are installed on MP3 players, many camera models, children's toys and even on the remote control of the TV. However, to continuously maintain a normal level of charge, you need to regularly charge them. And for this you need to have a special memory. In this article, we will learn all the features of a tool such as a battery charger, and consider its functions.

Characteristic

The term "charger" means a special device for charging batteries from the energy of external sources. Typically, such tools convert the voltage to 220 volts under 3.6 V (or what kind of charge is your model of the battery), thereby charging the device to the desired level. By this principle, all memory devices of this type operate.

It is customary to distinguish between a battery charger for power, or more precisely, with the maximum charging current that it can provide. This value on different memory models varies from 700 to 2000 mA. The more current the device generates, correspondingly, the less time it takes to charge the battery.

Presence of slots

Often, a standard battery charger (the instruction manual for its use is attached to each model separately by the manufacturer) has from 2 to 4 connectors for charging the batteries. In this case, the number of slots and their number is always a multiple of two. In addition, there is a memory device that can simultaneously work with different types of batteries. In this case, the device has 2 slots: under AA type batteries (finger) and the same number of connectors for AAA type elements (so-called little fingers). At the same time in the design of such memory is provided one connector, designed for the rechargeable "Crown". Its voltage is usually 9 V. The battery charger , which works with several types of batteries, is called a combined battery.

Protection against overheating and incorrect polarity

This function is available on almost all models of modern memory. It is very useful and even necessary, since it protects the memory and the battery itself from overheating and failure. If you forget about the operation of this device (which can lead to overheating and recharging) or install a battery with the wrong polarity, the presence of such a function will help you avoid such consequences.

Battery charger with LCD display

Unfortunately, not all models of battery chargers are now equipped with a display. There are options with LCD mini-display (exclusively black and white), but they are much more expensive than others. On such a charger for batteries, the price is about 1.5 thousand rubles. And if you have several devices working on this kind of battery, buying a device with such a device will not be superfluous for you. This display provides complete information about the electrical current, charging time and voltage. This is a very useful feature that allows you to track the status of the battery without removing it from the connector.
