Schematic diagram of the charger

Sometimes you need to charge the batteries of various devices, but there is no suitable charging, a universal battery charger will come to the rescue. The scheme of its operation is quite simple and compatible with almost any device. The universal charger has the following scheme of work.

Schematic representation of an electric universal charger

For different types of batteries, it is enough just to change the charge current. It should be 0.1 A of the battery capacity, then with such a charge, the battery will last for about 800 charge / discharge cycles, depending on the type of battery. The charging time, taking into account the current 0.1 A from the battery capacity, will be 10-12 hours.

Acid batteries need to be charged with a choice of discharge 10 times less than other devices. This is done using the S2 and S3 toggle switches on the adapter, where the current strength is 0.1 and 0.25 A, respectively. If both levers are connected, then the value is set to 0.35 A. From this it follows that the acid battery must be charged under the action of a current strength of 1, 2.5 and 3.5 A.

Universal charger for all types of batteries: technical features

Why universal battery chargers are good: choosing the best models
The choice of the adapter is based on the technical characteristics.

What parameters are best to consider when choosing a universal charger.

ParameterDescription
Type of batteries and accumulatorsThe device can be combined (when it is acceptable to use different types of batteries, including finger-type) or standard, which is designed for one carrier. It often charges AA or AAA-type rechargeable batteries, as well as mobile, crown, laptop (if there is a USB port) and others.
Current strengthThis parameter can be changed manually depending on the battery requirements. However, the higher the parameter, the faster the battery will charge. It is noted that online charging will shorten battery life.
Number of charging channelsThe more outputs for various installations, the more multifunctional the device is considered. It happens that purchased models have channels with different amperage.
Availability of additional features:Discharge: In the vast majority of cases, batteries are difficult to discharge to a minimum before charging. This function in the adapter is very convenient, as it allows you to completely discharge the battery. Display: The screen displays all the characteristics of the flowing charge, including amperage, voltage and operating time. Overheating and error protection: In the event of power surges, the device will help to avoid damage to the battery, as it stabilizes the charge channel. Also, the function is able to prevent the battery from burning out if it is installed in the wrong polarity.
Saving functionYou've probably heard about the Boost mode in the charger. What is this, every electronic knows. This is a function that switches itself off after a full charge of the battery, saving energy and preventing the battery from burning out. At the same time, it charges the battery for a certain time.

Some types of adapters are capable of operating on a non-traditional 12V network. This installation is practical, as it can be carried with you and even connected to a car cigarette lighter.

IMPORTANT!

To keep the battery in good condition, charge it fully for 14 to 16 hours once every few weeks, at least once a quarter.

If you do not have the opportunity to periodically charge the battery for such a long time, then try to use the battery at a moderate temperature and avoid deep discharges.

How to choose a universal battery charger: expert advice

If you are faced with an acute question of choosing a charging for a battery, you need to decide exactly where it will be used. In addition, pay attention to the following points:

  • manufacturer and its relevance. The more well-known the brand of charging, the lower the likelihood of becoming a victim of counterfeiting. Today on the market you can find installations from UFO, Sony, Samsung, Varta and others. These models are popular thanks to user reviews;
  • the integrity of the packaging and the operability of the adapter. When choosing, be sure to make sure that the device is not opened before you. The buyer must independently verify this, check the device for operability in the store;
Why universal battery chargers are good: choosing the best models
A large number of ports is a significant advantage for universal charging
  • nominal capacity of the installation. It is important that this parameter meets your requirements. 2000-10,000 mAh is enough to charge mobile devices, and a laptop and other equipment will require a large capacity;
  • charging power - this is an equally important parameter when choosing. Allowable battery charge current - 10% of its capacity;
  • the presence of a USB port. This feature is now quite comfortable, as it allows you to charge traditional home electronics;
  • be sure to decide on the type of adapter: can be portable, impulse and passive. The latter is ideal for cases where it is necessary to convert the current for high-quality and safe battery charging;
  • choose a suitable charging scheme for the installation. There are options that operate with constant current and those that operate with constant voltage. The first type does not guarantee a safe charge, since it does not protect against overheating, and the second is unable to fully charge the battery. Accordingly, the combination adapter should be selected.

These guidelines will help you find the most efficient and durable adapter for any device.

What is Charger Boost Mode: How It Works

Almost any charger with multiple functions has a quick charge (BOOST) mode. Such a function can help out if there is no time for deep charging. For example, if your phone runs out during an important call, and it takes at least 30 minutes to turn it on. In such a situation, it is better to use the BOOST mode, it will help reanimate the residual battery charge for a while.
