Sulfation over the lifetime of the battery

• 
• The chemical reaction which allows to the battery to generate energy is reversible whilst the battery keeps an adequate charging level.
• If the battery gets discharged too deeply, the Lead Sulfate sediments crystallise on the plates during the discharging phase. This can permanently effect performance and reduce battery life because the lead sulfate crystals will no longer be transformed in lead oxide during the charging phase.
