FAQ

1. Q: What are the Difference between Lithium Ion and Lithium Polymer?

A: Lithium ion:

*The lightest of all metals

*The greatest electrochemical potential

*The largest energy density for weight.

*The load characteristics are reasonably good in terms of discharge.

*The high cell voltage of 3.6 volts allows battery pack designs with only one cell versus three.

*It is a low maintenance battery.

*No memory and no scheduled cycling are required to prolong the battery's life.

*Lithium-ion cells cause little harm when disposed.

*It is fragile and requires a protection circuit to maintain safe operation.

*Cell temperature is monitored to prevent temperature extremes.

*Capacity deterioration is noticeable after one year (whether the battery is in use or not).

Lithium Polymer:

*Lithium polymer chemistry differentiates itself from Lithium Ion in the type of electrolyte used (a plastic-like film that does not conduct electricity but allows ion exchange - electrically charged atoms or groups of atoms).

*The polymer electrolyte replaces the traditional porous separator, which is soaked with electrolyte.

*The dry polymer design offers simplifications with respect to fabrication, ruggedness, safety and thin-profile geometry.

*Cell thickness measures as little as one millimeter (0.039 inches).

*Can be formed and shaped in any way imagined.

*Commercial lithium polymer batteries are hybrid cells that contain gelled electrolyte to enhane conductivity.

*Gelled electrolyte added to the lithium ion polymer replaces the porous separator. The gelled electrolyte is simply added to enhance ion conductivity.

*Capacity is slightly less than that of the standard lithium ion battery.

*Lithium ion polymer finds its market niche in wafer-thin geometries, such as PDA batteries.

*Improved safety - more resistant to overcharge; less chance for electrolyte leakage.

2. Q: My new battery is not taking a charge, is it defective?
A: New batteries from the factory are in a slightly discharged condition and must be fully charged before use. It is recommended that you fully charge and discharge the new battery two to five times to allow it to reach its maximum rated capacity. An overnight charge (approximately twelve hours) is recommended. It is normal for a battery to become warm during charging and discharging. When charging the battery for the first time, the device may indicate that charging is complete after just 10 or 15 minutes. This is normal with rechargeable batteries. At times, new batteries are more difficult for the application to charge; they must be conditioned. At times the charger will stop charging a new battery before it is fully charged. If this happens, simply remove the battery from the device and then reconnect it. This may happen several times during the first battery charge.

3. Q: What does Capacity mean?

A: Capacity is the measure of the energy stored in a battery. This is shown in the Ah (Ampere hour) or mAh (milli-Ampere hour), capacity defines the ability of a battery to perform under a specified discharge criteria

4. Q: What is self-discharge?
A: The loss of capacity in a battery due to internal chemical reactions. Self- discharge will occur within all batteries and is influenced by temperature. Self-discharge occurs no matter if the battery is connected to your device or not.

5. Q: Do batteries self discharge when not in use?
A: Yes, all batteries self-discharge. The rate of discharge depends on the type of battery and the storage temperature.

6. Q: What is cut off voltage?
A: The voltage at the end of a useful discharge. Cut off voltage will vary by device. However, the cut off voltage for a device specifies the inoperable point for the device utilizing battery power.

7. Q: What is a Cycle?
A: A cycle is considered one discharge and one charge sequence for a rechargeable battery

8. The voltage of Power Bank?
A: The devices with input voltage of 5V, 1A: iPad, iPhone, iPod, smart phone, MP3, MP4, PSP, digital camera, GPS etc.
The devices with input voltage of 8-12V: tablet computer, video camera, SLR camera etc.
The devices with input voltage of 12-24V: laptop computer.
