You can determine if a 12V battery is completely charged by measuring its voltage. A fully charged 12V lead-acid battery should have a voltage of around 12.6-12.8 volts. You can use a multimeter to measure the voltage across the battery terminals. If the voltage is lower than 12.6 volts, the battery is not fully charged.
Lead-Acid Battery Cells and Discharging. A lead-acid battery cell consists of a positive electrode made of lead dioxide (PbO 2) and a negative electrode made of porous metallic lead (Pb), both of which are immersed in a sulfuric acid (H 2 SO 4) water solution. This solution forms an electrolyte with free (H+ and SO42-) ions. Chemical reactions ...
A new lead-acid battery does not have to be jumped after the installation. They come fully charged from the manufacturing process. Some people reported that they need to jump a battery to start an engine, although it''s a brand new battery.
The main types of lead-acid battery are flooded (wet), AGM and gel. Lead-acid batteries are made up of 6 cells. Each cell provides 2.13V and when fully charged the whole battery has a voltage of 12.72V. Each cell has one positive plate and one negative plate. The positive plate has as a lead dioxide (PbO2) coating.
