Battery Disposal

Dry cell batteries are batteries used in many common items—including power tools, watches, video cameras, calculators, flashlights, toys and hearing aids.

They include:

  • Alkaline
  • Alkaline rechargeable
  • Lead acid sealed
  • Lithium
  • Metal hydride
  • Mercuric oxide
  • Nickel-cadmium
  • Silver oxide
  • Zinc-air batteries.

The materials in these batteries—mercury, lithium, silver cadmium, lead and acids—all have the potential to be hazardous wastes. If batteries are burned or landfilled, the heavy metals in them can be released into the environment. These batteries also contain valuable metals that can be recovered for reuse.

On the UWO campus we categorize batteries into alkaline, and heavy metal.

Alkaline batteries such as AA, AAA, C, D, 6 Volt, 9 Volt are currently not recyclable and should be thrown out in the normal trash.

All other heavy metal batteries should have both of the electrodes covered with tape and delivered to a central collection area for disposal or recycling.

Vehicle batteries should be stored in a designated collection area. On the UWO campus we have a contract with a certified scrap battery hauler that picks up used vehicle batteries weekly.
