How to Recycle Button Cell Batteries:
Button cell batteries are round, between 5 and 12 mm in diameter and commonly found in watches, hearing aids and calculators. According to the Mercury Education and Reduction Campaign, mercury was removed from alkaline batteries in 1996, but not from button cell batteries. If incinerated or left in landfills, mercury and other toxins can leak out and enter water supplies and food chains. Therefore, button cell batteries should be recycled and not put into the regular trash.

Battery run-time on a laptop is difficult to determine. Actual battery running time depends upon the power demands made by the equipment. The use of the screen, the hard drive, and other accessories results in an additional drain upon the battery, effectively reducing its running time. The total run-time of the battery is also dependent upon the design of the equipment.
Batteries in portable consumer devices such as a laptop, camcorder, cellular phone, etc, are typically made using either Nickel Cadmium (NiCad), Nickel Metal Hydride (NiMH) or Lithium Ion (Li-Ion) battery cell chemistry.
Lithium-Ion (Li-Ion) has become the new standard for portable power in consumer devices. Li-Ion batterys produce the same energy as NiMH battery but weighs approximately 20%-35% less. This is can make a noticeable difference in devices such as cellular phones, camcorders or notebook computers where the battery makes up a significant portion of the total weight.
