If the batteries in an electronic device have to be changed too often, then you should think about batteries, the capacity of which can be restored using a special charger.
Such charge recovery devices are compact in size and consume a small amount of electricity. What is the difference between different models of chargers, as well as how to choose the best quality product will be described in detail in this article.

What are the battery chargers
Battery chargers are divided into the following types:
- Multifunctional devices.
- Simple charging.
Intelligent chargers are more expensive, but allow you to control the level of charge. Also, multifunctional products can be classified as professional, because they allow you to charge various types of batteries.
Many smart models have the function of recognizing the type of element and its capacity, which allows the most efficient and safe use of the device to restore the battery capacity.
Simple charges are designed to recharge only one type of battery, so they have a minimum size, and their cost is significantly lower than the price of smart memory.
The principle of operation of the charger
In simple memory, the restoration of the battery capacity is carried out by supplying the rated voltage to the DC battery contacts. Such devices are small in size and are intended, as a rule, to charge only one type of battery.
Simple memories start working immediately after they are connected to a 220 V network, and there is an LED on the device case as an indicator of inclusion. Simple devices include models such as: Duracell cef14, Tank007 18650 ZU2 et al.
Intelligent models of chargers are complex electronic products that are equipped with sockets for charging various batteries. The cases of such memories are made with charge indicators, with which you can accurately determine the level of charge of the battery.
The functionality of modern devices is not limited only by the usual supply of a rectified electric current of the required voltage, but also allows the process of restoring the battery capacity with different intensities.
Most often, such devices have the following functions:
- Fast charge.
- Pre-charge.
- Drip charge.
The quick charge function is activated when it is necessary to restore the battery for a short time. This result can be achieved by applying high current to the contacts. You can also use this mode to recharge the battery.
The main disadvantage of this option to restore the battery capacity is its strong heating, which can not but adversely affect the total battery life.
Pre-charging is necessary when the product is completely discharged and a significant period of supplying a small current is required to fully charge the battery.
In the drip charging mode, the current is supplied in small portions, which also allows you to completely restore the product's performance without significant overheating.
Which batteries can be charged using the charger
Using the charger, you can charge the following batteries:
- Nickel cadmium.
- Nickel metal hydride.
- Li-ion.
The shape of the battery can be any. If the charger is designed to restore the capacity of batteries of various shapes, the device can be successfully used to charge the little, finger and disk products. Also, many memories allow you to restore the capacity of batteries of type D, C and "Krone".
Using universal chargers, you can restore the batteries of mobile phones, players, toys, and use them for vape batteries. Through a special USB adapter, such memory devices can be used to restore the capacity of almost any type of battery. You can also purchase a device of the type "Frog", with which you can also restore various battery products.
What to look for when choosing a charger
When choosing a charger should be guided by the following information:
- What type of batteries do you need to recover.
- How often do you need to charge the battery.
- The number of batteries.
If it is necessary from time to time to restore 1 or 2 elements of the same type, then it is enough to purchase the cheapest device. But when a large number of different batteries are available, then you can not do without the purchase of a professional charger.
If, for example, 8 batteries are installed in an electronic household appliance, then to restore the capacity of all elements you will need to purchase a capacious memory. As a rule, an instruction is attached to the device, which explains which batteries can be restored.
Popular battery chargers
In order not to make a mistake when choosing a charger for rechargeable batteries, a charger of well-known manufacturers is recommended. To date, the devices of the following companies are most popular with buyers:
- LiitoKala - The memory from this manufacturer differ not only in good quality, but also in low cost. Even in the middle price range, you can purchase a universal transformerless charger equipped with a display.
- Varta - devices from the German manufacturer of electrical goods are of the highest quality and reliability. Even with prolonged use of the products of this company, there are no deviations in the operating mode, and also there is no power drop when restoring the capacity of large batteries.
- Energizer - It has all the necessary qualities in order to award them first place in this rating, but the relatively high cost of products does not allow this.
- Sititec - A manufacturer of high-quality electronic products, including solar-powered memory. Products are not only reliable, but also at a relatively low price.
- GP - devices for restoring the capacity of batteries from this manufacturer have a low price and good quality. Most of the company's products are available for round batteries with a capacity of up to 2600 mA.
The products of any manufacturer from this list will make it easy to restore the battery to its rated capacity.
