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.
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
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.
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 or 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.
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.
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.
In science and technology, a battery is a device that stores energy and makes it available in an electrical form. It converts chemical energy into electrical energy, producing an electric current when connected in a circuit. The finished battery is an electrically connected group of cells (wired in series) that stores an electrical charge and supplies a direct current (DC). We usually call finished battery as battery pack and unfinished battery is called as cell.
Batteries are grouped into following categories: Alkaline battery Zincic carbolic battery Lead-Acid battery Nickel-metal-hydride Nickel-cadmium Lithium battery Li-ion battery Li-polymer battery Fuel cells Solar cells Other types of battery
A primary battery is not intended to be recharged and is discarded when the battery has delivered all of its electrical energy. A rechargeable battery is a galvanic battery which, after discharge, is restored to the fully charged state by the passage of an electrical current through the cell in the opposite direction to that of discharge.
Charger or electro circuit can't be fit for the battery. Overcharge and over-discharge, etc. Battery can't comply with the charging requirement The lifetime of a battery can be prolonged by: Using the original charger Charging the battery after it automatically powers off, then full charge the battery Avoiding erroneous usage of battery, such as heavy pressure, short circuit, fall off and so on
The battery has no voltage. The charger has no output electric current. Low charging efficiency due to external cause Solutions to the problem: Test whether the charger has voltage and output electric current or not. Check if the charger is well contacted with battery. Activate the battery with voltage and current 1.5 times higher than those of the battery. (Use this method only when the battery can't be charged.)
No voltage. External shot circuit or overcharge, anti-charge Cells expansion and short circuit caused by direct anode contact and continuous high efficiency electric current overcharging. It can be avoided by: Checking if the battery is without voltage or electric current Avoiding short circuit Avoiding collision and pressure among batteries Charging the battery after it automatically powers off, then full charge the battery.
A new battery usually maintains a discharged condition with very low capacity. It is highly recommended to fully charge new battery packs before using. You can refer to the users' guide of your electronic device for charging instructions. A new battery pack needs to be circled (fully discharged and recharged) three to five times to reach its optimum performance. Rechargeable battery will undergo self-discharging when left unused for a long period of time. Thus, it should always be stored in a fully charged state and kept in a cool, dry and clean place. To maintain the optimum performance of a battery pack, it is highly recommended to circle (fully discharging and recharging) it at least once a month. It is normal if a new battery gets warm when being charged or used. However, please pay special attention if the battery pack becomes excessively hot. This may indicate there is a problem with the charging circuit of the electronic device. Please consult a qualified technician if necessary. New batteries are hard to be charged. Sometimes, your electronic device may indicate a fully charged condition about 10 to 15 minutes when the new battery pack is being charged for the first time. When this happens, remove the battery pack and let it cool down for about 10 to 15 minutes then repeat the charging procedure. Sometimes, a new battery will suddenly refuse to be charged. If this happens, a suggested solution is trying to remove the battery from the device and insert it again.
Do not modify or disassemble it. Do not incinerate or expose battery to excessive heat, which may result in an exposure. Do not expose battery to water or other moist/wet substances. Avoid piercing, hitting, crushing or any abuse use of the battery. Do not forget to take away your battery from the device if you will not use it for a long time. Avoid short circuit of the terminals by keeping your battery pack away from metal objects such as necklaces or hairpins.
