WhatsAppAs a general rule, the higher the voltage, the more charge the battery has. However, the relationship between voltage and state of charge is not always linear. For example, a fully charged 12-volt lead-acid battery will have a voltage of around 12.8 volts, while a partially discharged battery may have a voltage of 12.2 volts or less.
WhatsAppIt can vary, and you can look for the battery datasheet). And it will kill the battery due to overheating. Not a good thing. But if you have a current regulator, you can plug it between the batteries and set the current to the standard maximum charge current (which is about 25% of the battery capacity), in this case, 25A, and let them equalize.
