However, traditional lead-acid batteries usually suffer from low energy density, limited lifespan, and toxicity of lead [5, 6].
Vented lead acid: This group of batteries is “open” and allows gas to escape without any positive pressure building up in the cells. This type can be topped up, thus they present tolerance to high temperatures and over-charging. The free electrolyte is also responsible for the facilitation of the battery’s cooling.
