Shaping the future through energy

The standout features of the lead batteries used in the M5BAT project are their optimised high current capability and long cycle life expectancy.

Basically, lead batteries are divided into two main categories: flooded or sealed.
Flooded or wet cell lead batteries have cells with a liquid electrolyte and are extremely reliable and low-maintenance.
Sealed or VRLA (Valve-Regulated Lead-Acid battery) lead batteries include both gel and AGM (Absorbent Glass Mat) batteries.
The distinctive feature of the gel technology is that the electrolyte is suspended in the gel, which achieves very high cycle life.
In AGM technology, the liquid electrolyte is contained in a glass mat. VRLA technology is maintenance-free with no need to top up the battery with water.
Modern lead acid batteries are environmentally compatible, efficient, low/no-maintenance and store energy reliably. They also achieve a recycling rate of up to 99%.

Sustainability and recycling

Unlike other energy storage technologies, lead batteries allow a recycling rate of more than 99%. The lead that is recovered is used to make new lead batteries, ensuring a cost-efficient and sustainable process.

Specifics of lead batteries

During the discharging process, lead (negative) and lead oxide (positive) are converted into lead sulphate.
The electrolyte (diluted sulphuric acid) is actively involved in the chemical reaction.
And the fact that – from a chemical perspective – both plates contain the same material (PbSO4) is what is typical of this specific type of rechargeable battery.


One cycle comprises one discharging phase and one charging phase.
