Q:How Are Batteries Rated? (What Are Volts and Amps?)
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 that the original battery found in your device. This is indicative of a longer run-time (high 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. What’s The Deal?
A:New batteries are shipped in a discharged condition and must be charged before use. We generally recommend an overnight charge (approximately twelve hours). Refer to your user’s manual for charging instruction. 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).
Q:What is the "Memory Effect"?
A:Ni-Cad batteries suffer from what’s called the "memory effect" This means that if a battery is continually only partially discharged before re-charging, the battery "forgets" that is 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 it’s 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 month. 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 ensure your battery remains healthy. Ni-Mh and Li-Ion batteries do not suffer the memory effect.
Q:Can I Upgrade My Devices Battery to a Newer Chemistry?
A:NiCad, NiMH and Li-ion are all fundamentally different from one another and cannot be substituted unless the device has been pre-configured from the factory to accept more than one type of rechargeable battery. The difference between them stems from the fact that each type requires a different charging pattern to be properly recharged. Refer to your owner’s manual to find out which rechargeable battery types your particular device supports. 

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 start again. This may happen several times during your first battery charge. Don’t worry; it’s perfectly normal.
