What is a safe way and a proper way to dispose batteries

Take them to a local Waste Management facility

Explanation:

Dispose of car batteries at an auto parts retailer or hazardous waste collection site. Since car batteries contain lead acid, they can't be disposed of in the trash or tossed in with your recycling.[3] Many retailers, like Home Depot or Auto Zone, will accept dead or used car batteries. You can also drop them off at recycling or waste disposal facilities that specialize in hazardous materials.

Take rechargeable batteries to a recycling facility. Rechargeable batteries contain nickel and cadmium, which can create an environmental hazard if the batteries are thrown away in a landfill or an incinerator. These batteries must be disposed of at a hazardous waste collection site, recycling facility, or an electronics retailer that recycles batteries.

Proper Disposal of Batteries. To safely dispose of batteries with lithium or batteries of greater than 9 volts, put clear packing, masking or electrical tape on the batteries’ terminals or sandwich the batteries between two layers of tape
