Frequently Asked Questions
Battery DisposalBatteries contain many hazardous substances and should be disposed of carefully and properly. Watch the video made by Battery Council International (The trade association for the lead-acid battery industry) for a guide.
Batteries should be recycled at an appropriate recycling center
What happens to my old battery?
The battery is broken apart in a hammermill, a machine that hammers the battery into pieces.
The broken battery pieces go into a vat, where the lead and heavy materials fall to the bottom while the plastic rises to the top. At this point, the polypropylene pieces are scooped away and the liquids are drawn off, leaving the lead and heavy metals. Each of the materials goes into a different "stream." We'll begin with the plastic, or polypropylene.
The polypropylene pieces are washed, blown dry and sent to a plastic recycler where the pieces are melted together into an almost-liquid state. The molten plastic is put through an extruder that produces small plastic pellets of a uniform size. Those pellets are sold to the manufacturer of battery cases, and the process begins again.
The lead grids, lead oxide and other lead parts are cleaned and then melted together in smelting furnaces.
The molten lead is poured into ingot molds. Large ingots, weighing about 2,000 pounds are called hogs. Smaller ingots, weighing 65 pounds, are called pigs. After few minutes, the impurities, otherwise known as dross, float to the top of the still-molten lead in the ingot molds. The dross is scraped away and the ingots are left to cool.
When the ingots are cool, they are removed from the molds and sent to battery manufacturers, where they are re-melted and used in the production of new lead plates and other parts for new batteries.
Old battery acid can be handled in two ways.
The acid is neutralized with an industrial alkaline compound similar to household baking soda.(ACID + ALKALINE=WATER + SALT) This turns the acid into water. The water is treated, cleaned and tested to be sure it meets clean water standards. Then it is released into the public sewer system.
Another way to treat acid is to process it and convert it to sodium sulfate, an odorless white powder that's used in laundry detergent, glass and textile manufacturing. This takes a material that would be discarded and turns it into a useful product.
