What payment means do you accept?
We accept credit card payment through PayPal payment system.
PayPal payment system supports VISA, MasterCard, Discover, eCheck and PayPal.
How to pay without having a PayPal account?
You can pay with a debit or credit card.
When is my credit card charged?
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, where items are to be shipped out by the end of the following business day.
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
Can I cancel an order?
Orders cannot be cancelled once the checkout process has been completed. Due to our commitment to process orders quickly, once the checkout process is completed our warehouse is immediately notified to pick and pack the order for shipment. We regret any inconvenience that this may cause you.
If you have any difficulties, please feel free to reach us by clicking the Contact Us button on the website. We will get back to you shortly.
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 Paypal servers, which use Secure Sockets Layer (SSL), an encryption technology that works with Firefox, Netscape Navigator, Microsoft Internet Explorer, and AOL's browser, so that customer's personal information can be protected.
Do you charge sales tax?
No, there is no sales tax for any orders ( No Commercial Value).

Can I come to your locations to pick up an item?
Unfortunately, we are not currently configured for individuals to come to our locations to pick up their orders. We are merely an office for processing the paperwork for these transactions.
What will I be charged for shipping?
Shipping and handling charges vary greatly depending upon the value of the materials and craftsmanship of the piece and its final shipment destination. The shipping and handling rates are clearly posted in each item's description and are non-negotiable. Please consider this when placing your order.
Who will deliver my orders?
Items will be shipped by USPS, Royal Mail, Deutsche Post and Hongkong Post Air-Mail. We may use other carriers as necessary.
How long will it take for my item to reach me?
Please note that business days, excluding Saturdays, Sundays and Public Holidays, are calculated in terms of delivery period. In general, it takes about 7 - 15 business days for delivery.
How do I track my shipment?
We ship your purchase before the end of the next business day after you have checked-out. We would send an e-mail with the tracking number so you can check the progress of your delivery at the carrier's web site.
What should I do if my shipment never arrives?
Please allow up to 10 business days for your item to be delivered. If it still does not arrive, please reach us by clicking the Contact Us button on the website. We will get back to you shortly.
How do I ship items to a different address?
During our checkout process, specify where you want your purchase shipped. It can be different from your credit card billing address. You may specify any ship-to street address.
- How can I return or exchange an item?
- Can I get a refund?
- Can I return any product for any reason and receive a full refund?
Can I return or exchange an item?
Yes. Please review our Return Policy above to find out about returns and exchanges.
Can I get a refund?
If you are not satisfied with any of our product(s) in any way, we will gladly replace the product(s), or refund your money when the product(s) are returned within 30 days of purchase. After the initial 30 days of purchase, we offer replacements, but no refunds, for defective products up to 12 months from original purchase.
Refunds are issued in the same form of payment as in the original transaction within 10 business days of receiving your return. Please review our Return Policy above for details on how to get a refund.
Can I return any product for any reason and receive a full refund?
No, we cannot refund shipping and handling. Due to our aggressive pricing, shipping charges are non-refundable unless we shipped incorrect item(s).

What is a battery?
A battery is a device that generates an electrical current by electrochemical reaction..
What is a battery pack?
A battery pack is an assortment of two or more battery cells, configured in a predefined order - a series, parallel or a mixture of both - to deliver the desired voltage, capacity, or power density.
What is Volt?
Volt (V), short for voltage, is a measure of electrical force or electrical pressure. The terminal voltage, measured in volts, of a battery is the electrical potential difference across its two terminals. Battery cells of different chemistries have different voltages. A nickel-based cell, like NiCd and NiMH, provides a nominal cell voltage of approximately 1.2 V and a Li-ion cell provides 3.6V/3.7V.
The voltage of two battery cells, of the same chemistry, is always the same. Their capacities may be different, but the voltage always remains the same. Higher terminal voltages are obtained by assembling two or more cells in a series, parallel or a mixture of both. For example, a 7.4V, Li-ion battery would be made up of 2 cells connected in a series.
It is important that the voltage of a cell or a battery pack always matches the voltage requirement of the device in which it is used. If there is any mismatch of the two voltages, the device will not function. Excessive exposure to a different voltage may also damage the equipment. Equipment users should take special care that the batteries they are using matches the voltage requirement of their device.
What is milliampere-Hour (mAH)?
It is a unit of measurement of battery capacity, i.e. the amount of power packed into a battery. It is obtained by multiplying the current in miliamperes (mA) by the length of time that the current is flowing, abbreviated mAH. Higher "mAH" rating means higher battery capacity, which results in longer battery life between charges.
What is the "Memory Effect"?
Ni-Cd batteries, and to a lesser extent Ni-MH batteries, suffer from what's called the "memory effect". What this means is that if a battery is repeatedly only partially discharged before recharging, the battery "forgets" that it has the capacity to further discharge all the way down. To illustrate: If you, on a regular basis, fully charge your battery and then use only 50% of its capacity before the next recharge, eventually the battery will become unaware of its extra 50% capacity which has remained unused. The battery will remain functional, but only at 50% of its original capacity. The way to avoid the dreaded "memory effect" is to fully cycle (fully charge and then fully discharge) the battery at least once every two to three weeks. Batteries can be discharged by unplugging the device's AC adapter and letting the device run on the battery until it ceases to function. This will insure your battery remains healthy.
What is a battery cycle?
Cycle life is measured by the amount of times a battery may be charged and discharged. Every time a battery is charged and discharged, it uses one cycle. Cycle life is very important in battery applications such as laptop batteries and emergency light batteries. A Ni-Cd battery has a cycle life of 500-1000 or more cycles.
What is self-discharge?
Self-discharge is the loss of charge in a battery when not in use. Unused batteries lose their charge over time. The loss of charge, or self-discharge, is the highest right after charge when the battery holds full capacity. Other factors like humidity and temperature of the storage place also contributes to the rate of self-discharge.
All battery chemistries self-discharge. Li-ion batteries have the lowest self-discharge rate at 5% to 10% per month as compared to NiCd, at 20% per month, and NiMH, at 30% per month, under identical conditions.
What is battery life?
It is the number of battery cycles, a full charge followed by a full discharge, a battery can offer before it needs to be replaced. Li-Ion batteries generally offer around 300 charge/discharge cycles.
