entering a battery, as this may cause short circuits.
Leakage Handling
NO TICE
Electrolyte overow may damage the equipment. It will corrode metal parts and
boards, and ultimately damage the boards.
Electrolyte is corrosive and can cause irritation and chemical burns. Should you
come into direct contact with the battery electrolyte, do as follows:
● Inhalation: Evacuate from contaminated areas, get fresh air immediately, and
seek immediate medical attention.
● Eye contact: Immediately wash your eyes with water for at least 15 minutes,
do not rub your eyes, and seek immediate medical attention.
● Skin contact: Wash the aected areas immediately with soap and water and
seek immediate medical attention.
● Intake: Seek immediate medical attention.
Special requirements for lead-acid batteries:
NO TICE
When the battery temperature exceeds 60°C, check whether the electrolyte leaks.
If the electrolyte leaks, take proper measures promptly.
NO TICE
If the electrolyte leaks, follow the instructions of the battery manufacturer or use
sodium bicarbonate (NaHCO3) or sodium carbonate (Na2CO3) to neutralize the
electrolyte.
