If you charge ordinary dry batteries at home, the voltage will not increase. Rechargeable batteries are charged and discharged through chemical reactions, and there must be some losses during the process, which is why the battery has a lifespan. In professional battery terminology, there is an equalization charge and a float charge. In a simple sense, equalizing charge means the current is constant, while floating charge means the voltage is constant. Equalizing charging will increase the voltage. For example, a normal 2.25V battery will reach a maximum of 2.35V during equalization charging, and the limit will reach 2.25V during float charging (ideally lossless), and those we normally use at home. It can only have a certain voltage, which is equivalent to a floating charge, and the story will not increase
