There are basically three types of batteries that boaters are most likely to use: lead acid, rechargeable nickel-cadmium (NiCad) and alkaline.

Lead-acid batteries contain lead and sulfuric acid, both of which are toxic to the marine environment. As a result, most states have enacted recycling laws for lead-acid batteries and most battery dealers take back your old battery for recycling. BoatUS, actually charges an additional fee upon purchase of a new battery if you do not bring in your spent one. Marine centers also accept old batteries for recycling.

At the recycling centers, lead and plastic are extracted and sent to a new battery manufacturer. Today, new lead-acid batteries can be expected to contain somewhere between 60 and 80 percent recycled materials.

For additional information on where to recyle lead-acid batteries, try the Battery Council.

NiCad batteries are another proposition. Used in everything from laptops, to cameras, phones and power tools, they can be recycled through a program sponsored by the Rechargeable Battery Recycling Corporation (RBRC) in cooperation with participating retailers. To find a vendor in your area, check out the RBRC website.

Although you can toss your alkaline batteries into the trash, chances are your county or municipality sponsors a curbside collection once or twice a year for hazardous household waste–a far preferable solution. Your local public works or sanitation department can provide you with a schedule and further details.
