2.When is my credit card charged?
3.What do you consider my billing address?
4.Are credit card transactions safe?
5.What is the difference between Ni-Cd, Ni-MH, and Li-ion?

8.WHAT IS NTSC AND PAL STANDARD?
1.What is sulfation of batteries?
Sulfation is the formation or deposit of lead sulfate on the surface and in the pores of the active material of the batteries'''''''' lead plates. If the sulfation becomes excessive and forms large crystals on the plates, the battery will not operate efficiently and may not work at all. Common causes of battery sulfation are standing a long time in a discharged condition, operating at excessive temperatures, and prolonged under or over charging. (Return to Top)

2.When is my credit card charged?
We accept Visa and MasterCard and debit cards including JCB, Maestro-UK and Solo. Paypal is also accepted at our secure checkout site.
Your credit card is charged immediately upon completion of the checkout process. Sophisticated systems are set up to immediately send your order to our shipping department, to be shipped out by the end of the following business day.

3.What do you consider my billing address?
Your billing address is the same address information on file with your credit card company. When entering this information during the checkout process it is important that you enter this information exactly as it appears on your credit card statement. If the information is not accurate, your card may be declined.

4.Are credit card transactions safe?
Absolutely! In fact, it''s statistically safer to use your credit card over the Internet than in a restaurant or department store. Payments are gone through WorldPay servers, which use Secure Sockets Layer (SSL), an encryption technology that works with Netscape Navigator, Microsoft Internet Explorer, and AOL''s browser, so that customer''s personal information can be protected.

5.What is the difference between Ni-Cd, Ni-MH, and Li-ion?
Li-ion (Lithium Ion). This is one of the newest cell types available. It is also the lightest battery type currently available on a commercial basis and can provide more power than the other main cell types. There are no known problems of memory effect with this battery type and it is the easiest battery type to care for. The downside of this battery is that it has the highest engineering costs and therefore the price is usually considerably higher than other cell types.
Ni-MH (Nickel Metal Hydride). This cell type is the most common cell type currently available for laptop computers (although Li-ion is rapidly becoming the most popular). This battery type is relatively cheap to manufacture and therefore tends to be cheaper than Li-ion. This cell type is prone to memory effect, so it is important to take good care of your Ni-MH battery to ensure that you obtain the best runtimes.
Ni-Cd (Nickel Cadmium). This is one of the oldest cell types and is generally only found in older laptops. The main pro for this cell type is its ability to handle higher loads, and therefore is more commonly found in portable power tools or devices that need a lot of power to work efficiently. The main downside of this cell type is that it is notorious for suffering from memory effect, so good care must be taken with this battery type to ensure most effective use of battery.

6.What is a "Smart" / "Intelligent" battery?
"Smart" / "Intelligent" batteries have internal circuit boards with smart chips which allow them to communicate with the notebook and thus better monitor battery performance, output voltage and temperature. Smart batteries will generally run 15% longer due to their increased efficiency and also give the computer much more accurate "fuel gauge" capabilities to determine how much battery running time is left before the next recharge is required.

7.Do I need to completely empty the battery before charging it, and does doing this prevent the so-called "memory effect"?
You don''t need to empty the battery before charging it. Lithium-based batteries, like those used in iPod, have none of the memory effects seen in nickel-based rechargeable batteries. (Return to Top)

8.WHAT IS NTSC AND PAL STANDARD?

Although VHS video format is the same throughout the World, the video standard or electronic signal that is recorded on the cassette varies from country to country. The two most common video standards used are NTSC and PAL.

NTSC is the video system or standard used in North America and most of South America. In NTSC, 30 frames are transmitted each second. Each frame is made up of 525 individual scan lines.

PAL is the predominant video system or standard mostly used overseas. In PAL, 25 frames are transmitted each second. Each frame is made up of 625 individual scan lines.



To determine your video standard refer to the chart below:
