Not only is recycling your laptop battery the right thing to do, it could be the only legal option. Computer Hope notes that the United States has more than 500 recycling laws; depending on where you live, you may be mandated to recycle that old battery. With a few phone calls, you can determine the best recycling option for you and take advantage of local drop-off programs or nationwide mail-in programs to recycle your laptop battery.
Take your laptop battery to an office supply store that offers electronics recycling. As Computer Hope notes, Best Buy, Radio Shack, Office Max and Office Depot all offer electronics recycling in the store.
Purchase an iRecycle kit from Battery Recycling (see Resources), then place your laptop battery inside and send it back to them. In addition to laptop batteries, they recycle every type of battery and many other electronic items. They sell kits from 5.44 to 22.7kg. and include shipping, materials and recycling fees in their price. In 2010 a 5.44kg. kit cost £22.70; this can fit the laptop battery and much more.
Contact your laptop manufacturer directly to inquire about battery recycling. Many companies offer laptop-recycling programs for their products that allow you to mail in items. Recycle the used laptop battery through your computer manufacturer if it offers such a program.
Call your town's recycling office to determine whether they offer a laptop battery-recycling program or an electronics waste recycling program that will allow you to recycle the battery in your community. Follow their recommended procedures for local recycling, if it's an option.
