Lead Accumulators

Lead accumulators are actually batteries . That’s right, the ones we use in cars.

These accumulators or batteries supply the vehicle with electrical energy for its engine.

The inventor of this device was the French engineer Gastón Plante who, in 1859, built the first lead accumulator, using lead plates dipped in an aqueous solution from the dilution of sulfuric acid.

The batteries we use today are much more modern, as they are manufactured to last longer and, for that, the electrodes are made of lead and mixed with antimony.

Lead accumulator discharge – is the transformation of chemical energy into electrical energy.

accumulator charge– when it is connected to a generator of 6 volts on average, whose generator and accumulator poles are positive with positive and negative with negative, current flows through the accumulator that is opposite to the direction of the current.

Accumulator efficiency – has an average of 80% and is defined by the relationship between the energy supplied at discharge and the energy received at load.

Capacity of the accumulator – this is the most important factor of the accumulator, because it is the total electrical charge supplied until it is discharged.
