4LR44 battery

What are the important uses of 4LR44 battery?

4LR44 battery refer to batteries used in solar power generation equipment, wind power generation equipment and renewable energy storage.

The important uses of 4LR44 battery are as follows:

(1) Voltage regulation (stable voltage)

Since the working characteristics of solar cells are affected by changes in the intensity of sunlight (irradiation), temperature and other factors, if the solar cell module is directly connected to the load, the load is often difficult to operate in the best working state, and the system efficiency is very low. However, when the battery is used as an energy storage battery, it will clamp the working voltage of the solar cell, converting the solar cell to charge the energy storage battery, and the energy storage battery will supply power to the load steadily (especially voltage), ensuring that the system operates in the best working state.

(2) Supply instantaneous high current discharge

The use of solar photovoltaic systems is expanding, especially off-grid solar photovoltaic systems. When they enter thousands of households, they will be used as the starting power of household appliances such as refrigerators (compressors), electric vehicles and motors, because such electromechanical equipment requires a large current to start, and the starting current is often 5 to 10 times the rated working current. The solar cell components in the photovoltaic system are affected by the maximum short-circuit current and the limitation of light intensity. The photovoltaic cell array is difficult to cope with the starting current requirements. If a battery is used, a large current can be supplied to the load for startup in an instant.

(3) Storing electric energy

In most off-grid photovoltaic systems, the voltage and current of the photovoltaic cell (solar panel) array cannot be completely consistent with the load (electrical appliance). Especially when natural conditions change, the light intensity changes on cloudy days, rainy days, and at night, the photovoltaic cell cannot supply full load energy, which makes it difficult for the electrical appliance (load) to use normally. With a battery for energy storage and the ability to regulate its energy metabolism, the photovoltaic system equipped with an energy storage device can satisfactorily and steadily supply the required electric energy to the electrical appliance. Therefore, it is very necessary to use 4LR44 battery to store energy for the photovoltaic system.
