• What is the difference between NiCad, NiMH and Lithium Ion batteries?

• 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. Each type of rechargeable battery chemistry has its own unique characteristics:
  
  NiCad and NiMH:
  The main difference between the two is that NiMH battery (the newer technology of the two) offers higher energy density than NiCads. In other words, the capacity of a NiMH is approximately twice the capacity of its NiCad counterpart. What this means is for you is increased run-time from the battery with no additional bulk or weight. NiMH also offers another major advantage: NiCad batteries tend to suffer from what is called the "memory effect". NiMH batteries are less prone to develop this problem and thus require less maintenance and conditioning. NiMH batteries are also environmentally friendlier than NiCad batteries since they do not contain heavy metals (which present serious landfill problems). Note: Not all devices can accept both NiCad or NiMH batteries.
  
  Lithium Ion:
  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. Another reason Li-Ion batteries have become so popular is that they do not suffer from the "memory effect" at all. They are also environmentally friendly because they don't contain toxic materials such as Cadmium or Mercury.

• What does shipping cost?

• To calculate the cost of shipping, choose the country to deliver goods.
  
  Then our system list the shipping cost on the down column of the webpage.

• What are the different ways you ship to me?
