Plante Batteries

Plante Batteries were invented by the French Scientist Gaston Plante in the year 1859.  The Plante Battery was the first rechargable battery.  It is also the first lead acid battery.

As a  lead acid battery, the Plante Battery uses pure lead plates.  The advantage of the Plante battery is that the capacity remains the same throughout its life.  Its grid design enables it to generate high currents and is thus suitable for applications which require high bursts of currents.  The active material in the positive plate is generated and regenerated throughout its lifetime.  Hence, there is  no loss of capacity. 

Each cell typically has a voltage of 2 volts.  Its ampere hour efficiency is 90%. 

The downside of this battery is its large size and high cost.
