Frequently Asked QuestionsQ:How are batteries rated?
A:There are two ratings on every battery: volts and milliamp-hour (mAh). The voltage of the new battery should always match the voltage of your original. Some of our batteries will have higher amp-hour ratings than the original battery found in your device. This is indicative of a longer run-time (higher capacity) and will not cause any incompatibilities. Remember: in some cases, the voltage will differ from the original battery. This often happens when both a Li-Ion battery and a Ni-Mh battery are available for the laptop.
Q:My new battery isn't charging. Is it defective?
A:New batteries are shipped in a discharged condition and must charged before use. We generally recommend an overnight charge (approximately twelve hours). Refer to your user's manual for charging instructions. Rechargeable batteries should be cycled - fully charged and then fully discharged - 2 to 4 times initially to allow them to reach their full capacity. (Note: it is perfectly normal for a battery to become warm to the touch during charging and discharging).
New batteries are hard for your device to charge; they have never been fully charged and are therefore "unformed". Sometimes your device's charger will stop charging a new battery before it is fully charged. If this happens, simply remove the battery from your device and then re-insert it. The charge cycle should begin again. This may happen several times during your first battery charge. Don't worry; it's perfectly normal.
Q:How can I maximize battery performance?
A:There are several steps you can take to insure that you get maximum performance from your battery:
Breaking In New Batteries - new batteries come in a discharged condition and must be fully charged before use. It is recommended that you fully charge and discharge your new battery two to four times to allow it to reach its maximum rated capacity.
Preventing the Memory Effect - Keep your battery healthy by fully charging and then fully discharging it at least once every two to three weeks. Exceptions to the rule are Li-Ion batteries which do not suffer from the Memory Effect.
Keep Your Batteries Clean - It's a good idea to clean dirty battery contacts with a cotton swab and alcohol. This helps maintain a good connection between the battery and your portable device.
Exercise Your Battery - Do not leave your battery dormant for long periods of time. We recommend using the battery at least once every two to three weeks. If a battery has not been used for a long period of time, perform the new battery break in procedure described above.
Battery Storage - If you don't plan on using the battery for a month or more, we recommend storing it in a clean, dry, cool place away from heat and metal objects. Ni-Cd, Ni-MH and Li-Ion batteries will self-discharge during storage; remember to break them in before use.
For Notebook Users - To get maximum performance from your battery, fully optimize the notebook's power management features prior to use. Power management is a trade off: better power conservation in exchange for lesser computer performance. The power management system conserves battery power by setting the processor to run at a slower speed, dimming the screen, spinning down the hard drive when it's not in use and causing the machine to go into sleep mode when inactive. Your notebook user's guide will provide information relating to specific power management features.
Q:What is the different of Ni-Cd, Ni-MH and Li-ion?
A:Batteries in portable consumer devices (laptops and notebooks, camcorders, digital camera, etc.) are principally made using either Nickel Cadmium (Ni-Cd), Nickel Metal Hydride (Ni-MH) or Lithium Ion (Li-ion) technologies. Each type of rechargeable battery technology has its own unique characteristics:
Ni-Cd and Ni-MH: the main difference between the two is the fact that Ni-MH batteries (the newer of the two technologies) offer higher energy densities than NiCads. In other words, pound for pound, Ni-MH delivers approximately 100% more capacity than its Ni-Cd counterpart. What this translates into is increased run-time from the battery with no additional bulk to weigh down your portable device.
Ni-MH also offers another major advantage: NiCad batteries tend to suffer from what is called the "Memory Effect". Ni-MH batteries are less prone to develop this dreaded affliction and thus require less maintenance and care. Ni-MH batteries are also more environmentally friendly than their Ni-Cd counterparts, since they do not contain heavy metals (which present serious landfill problems).
Li-ion has quickly become the emerging standard for portable power in consumer devices. Li-ion batteries produce the same energy as Ni-MH batteries but weigh approximately 35% less. This is crucial in applications such as camcorders or notebook computers, where the battery makes up a significant portion of the device's 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 better for the environment because they don't contain toxic materials such as Cadmium or Mercury.
Q:How long do batteries last?
A:The life of a rechargeable battery operating under normal conditions is generally between 500 to 800 charge-discharge cycles. This translates into one and a half to three years of battery life for the average user. As your rechargeable battery begins to die, you will notice a decline in the running time of the battery. When your two hour battery is only supplying you with an hour's worth of use, it's time for a new one.
Q:What sort of problems will I have with rechargeable batteries?
A:Rechargeable batteries lose their charge sitting in the camera. Ni-MH batteries lose between 1% - 4% of their charge a day. Since many cameras start reporting a low battery at 80% of full charge, the batteries could be reported low in as little as ten days. This number will vary greatly depending upon the age of the battery, temperature, and camera.
Memory effect was a problem with older Ni-Cd batteries. This problem has been reduced with newer batteries and chargers, though how you use your batteries may also impact performance. Ni-MH batteries do not have this problem, nor do the Li-Ion batteries.
Q:What is the "Memory Effect"?
A: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 continually only partially discharged before re-charging, 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. Your 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) your battery at least once every two to three weeks. Batteries can be discharged by unplugging the device's AC adaptor and letting the device run on the battery until it ceases to function. This will insure your battery remains healthy.
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.
