What Should A 12 Volt Battery Read Fully Charged. What should a 12 volt battery read when fully charged. The battery is not charged and could be bad if the reading.
Specific gravity is read with a hydrometer. What amps should a 12 volt battery read when fully charged. In fact 12 volt is just a term used to distinguish one battery from another.
When the multimeter reads 128 volts then your battery should not be charged any further because it is fully charged.
For a 12v lead acid this is typically 144 v fast and 138 standard and maybe 131 maintainance If my dead battery at 122 volts is connected to a charger the voltage star. The density or specific gravity of the sulphuric acid electrolyte of a lead-acid battery varies with the state of charge see table below. If it reads 126 volts the battery is just attaining a fully charged state. A 12-volt battery is a term used to distinguish between exceptional styles of batteries.
