Batteries which can be recharged are known as accumulators. These are electrochemical accumulators whose reaction is based on the lithium element. Since the 2000s, accumulators have offered the greatest specific energy (energy to mass ratio) and the greatest energy density (energy to volume ratio). A lithium cell without an integrated protection circuit is an unstable technology and non-compliance with the given guidelines can, in some cases, cause severe, irreversible physical injuries and material damage such as the risk of explosion, burns, electrocution, etc.
