Risk of injuries and health problems
• If the liquid acid leaks or becomes oxidised, avoid any contact
with the skin, eyes and mucous membranes. In the event of
contact with battery acid, rinse the point of contact
immediately with plenty of clean water and seek medical
attention immediately.
• Batteries should be removed from the unit when they are
spent, or if they are not being used for prolonged periods.
This will prevent damage due to leaks.
• Do not expose the batteries to extreme conditions by placing
them on radiators, for example. Increased risk of leaks!
• The batteries must not be charged, opened, thrown into fire
or short-circuited. Risk of explosion!
Battery recycling
• Do not dispose of batteries with the ordinary household
waste. To protect the environment, batteries should be
disposed of in line with the regulations in force.
• Never recharge non-rechargeable batteries. Do not
disassemble batteries. Do not throw them into the fire.
• Do not incinerate them.
