Battery recycling
Batteries and electric accumulators contain several substances that can have a harmful fect the environment the batteries are not properly recycled after Improper disposal batteries can contaminate the groundwater , and NEW HOLLAND strongly recommends that you return all used batteries a NEW HOLLAND dealer , who will dispose the used batteries recycle the used batteries properly some countries, this a legal requirement.
Mandatory battery recycling
NOTE: The following requirements are mandatory
Batteries are made lead plates and a sulfuric acid solution. Because batteries contain heavy metals such lead, CONAMA Resolution 401 / 2008 requires you return all used batteries the battery dealer when you replace any not dispose batteries your household
Points sale are obliged to:
• Accept the return your used batteries
• Store the returned batteries a suitable location
• Send the returned batteries the battery manufacturer for recycling
