Batteries: Toss or Recycle?

Batteries: Toss or Recycle?
May batteries be safely discarded along with other household trash, or must they be recycled? While newer batteries contain less mercury and other toxic substances than older versions, they do include trace amounts that could potentially harm the environment.

Prepared For Power Outage
If you cannot afford to buy an portable emergency power generator, you can make your own DIY generator, use 12 volt batteries or compact solar power units to run some basic 12 volt operating pieces of aquarium equipment or adaptable appliances to provide life support during a power failure.
