Disposal of Used Batteries
If any of the batteries are found to be leaking, place them in a suitable container that can withstand sulphuric acid
and dispose of them in accordance with local regulations.
Lead-acid batteries are classified as hazardous waste material and represent a key item in the control of battery
pollution control. Batteries must be stored, transported, used and disposed of in accordance with national and local
legal requirements and all other criteria applicable to the treatment of hazardous waste material and waste battery
pollution prevention.
According to the applicable regulations, waste lead-aid batteries must be recycled, while all other disposal methods
are prohibited. Uncontrolled or random disposal of waste lead-acid batteries, or other improper disposal methods
can result in serious environmental pollution, which will be investigated by the relevant authorities.
