Each house has appliances that power AA and AAA batteries. Some gadgets absorb a lot of energy. It is much more profitable for them to use NiMH batteries. Their capacity is comparable to the capacity of expensive disposable batteries. Moreover, they can be used up to 3 thousand times. With proper care, the batteries will last about five years. They are charged with special devices.
Device selection
The use of low-quality chargers significantly reduces the battery life. Manufacturers offer a huge number of devices for fast charging of nickel batteries. They use high currents (1000 mAh and higher).
When choosing a device, you need to pay attention to the following factors: the presence of separate slots for each battery, functionality (determining the full battery charge, discharge), the presence of protective systems, the ability to work with different sizes of batteries, and charging time.
Robiton
Robiton is a Russian brand specializing in the production of power supplies. The company appeared on the Russian market in 2004. Robiton procharger smart charger is designed to charge nickel-cadmium batteries. It is equipped with overcharge and overheat protection. The device has four slots. Using the Robiton charger, you can charge one or several elements of different sizes.
At the bottom of the model are the control buttons and cooling holes. There are two inputs on the case: for usb and a network adapter. Using the device, you can charge devices directly. The user independently adjusts the current strength. The Robiton charger operates in three modes: charge, discharge, test and restore.

Opportunities
The device supports sizes AA and AAA. First, the user selects the desired mode and amperage using the control buttons. Using the "Data" button, you can choose which information will be displayed on the screen. These are amperage, charging time, voltage and battery capacity. Using the number buttons, the user selects a slot with a battery.
In reviews of the Robiton charger, users particularly appreciated the availability of additional features. The "Discharge" function allows you to extend the battery life. Many appliances turn off when the battery is not fully discharged. When charging such a battery, part of its capacity is lost and its service life is reduced. To prevent this effect, it is recommended that you fully discharge the battery. Many users drain their batteries by inserting them into a flashlight. But this method can lead to overdischarge of the battery. It is better to use the charger function.
The "Test" mode allows you to evaluate the battery capacity. Using the Restore function, you can extend the life of your old battery. The disadvantage of the device is the lack of backlight display. The charger must be used indoors. Do not expose it to moisture, high temperatures, vibration and shock. Use a soft cloth to clean the case and screen. Do not store the device near heat sources. After use is complete, you must disconnect the machine from the network. Do not disassemble the device. This may result in fire or electric shock. It is better to entrust the repair to a professional master.
