"  They&amp;#039;re in our remote controls, cell phones, alarm clocks, toys, just about everything. While we couldn&amp;#039;t get by without them, some batteries can be a threat to our environment. Unless they&amp;#039;re disposed of properly, heavy metals including mercury, lead, cadmium and nickel can leach into the environment and water supply.Here&amp;#039;s how to tell which are hazardous, which aren&amp;#039;t, and how to dispose of them properly: Hazardous: Large lead-acid batteries (found in most cars), button cell batteries (such as those found in watches, hearing aids, and calculators), and disposable lithium batteries can all be hazardous. Bring them to a Household Hazardous Waste Collection Site where they&amp;#039;ll be handled in a way that won&amp;#039;t harm the environment. Visit Earth911 to find a collection site near you. Nonhazardous: Alkaline, lithium ion, nickel metal hydride, and carbon zinc batteries are all in this group. These are common batteries sized from AAA to D that we use in flashlights, toys, and other electronics. You can dispose of them by placing in the garbage or recycling. There&amp;#039;s also a mail-in recycling program called Battery Solutions which will recycle batteries for you. It&amp;#039;s a good idea to go through your battery drawer and discard any batteries that no longer work. Make a point of picking up new ones in the sizes that you&amp;#039;re out of or low on. This way, the next time you want to get a new electronic toy going, you won&amp;#039;t have to scrounge around looking for the right size battery and maybe have to settle for delayed gratification. When you&amp;#039;re buying new batteries, consider nickel cadmium (Ni-Cd) or nickel (Ni-MH) rechargeables- --they&amp;#039;ll cost a bit more up front but will last a lot longer, quickly paying for themselves.
