The Panasonic battery is a relatively good brand product and it is used in many applications. To summarise, the main functions of the battery are the following.
Firstly, electrical equipment and vehicles are in fact not electrically charged per se, its main fuel is oil, but batteries are essential for motor vehicles, because to headlights, horns, etc. are dependent on batteries to provide current in order to work. But the battery has a limited capacitive storage capacity and its more immediate role is to provide current for the generator when it fails to supply current when it starts. So inside the motor vehicle, the battery is connected to the generator, and is connected in parallel, which can provide a strong current when the engine starts.
Secondly, if the generator fails and loses its power generation function or the voltage is too low, many electrical products on the motor vehicle will not work properly, and with the battery, it can provide current for the electrical appliances in case of emergency, so that the equipment on the motor vehicle can be energised normally.
Thirdly, Panasonic batteries also have the greatest benefit of being able to store electricity, the realisation of this function requires two conditions at the same time, one is that the generator load is relatively small, there is excess electricity for the battery inside the active material and electrolyte chemical reaction, the second is that the battery capacity is insufficient.
