Lead

Lead-Acid batteries are rechargeable accumulators that use lead dioxide (PbO₂) as the positive electrode and porous lead (Pb) as the negative electrode, immersed in an acid electrolyte (H₂SO₄ – diluted sulfuric acid). This technology, although invented in 1859, remains widely used thanks to its reliability, affordability, and robustness.

Characteristics:

The low cost of lead-acid batteries makes them essential in stationary applications and the automotive sector, notably:

Good suitability for permanent recharge (backup)
Relatively low self-discharge
No legislative constraints on transport for so-called sealed batteries
Very low energy density, thus not suitable for embedded applications
High sensitivity to deep discharge
Low cycling capability

Examples:

YUASA NP7-12, NP1.2-12, NP38-12, CYCLON
