Battery care and use instructions   
  • Your new battery comes in a discharged condition and must be charged before use. Upon initial use (or after prolonged storage period) the battery may require two to three charge/discharge cycles before achieving maximum capacity.
  • If the battery will not be in use for a month or longer, it is recommended that it be removed from the device and stored in a cool, dry, clean place.
  • It is normal for a battery to become warm during charging and discharging.
  • A charged battery will eventually lose its charge if unused. It may therefore be necessary to recharge the battery after a storage period.

Battery dont's   
  • Do not short-circuit. A short-circuit may cause severe damage to the battery.
  • Do not drop, hit or otherwise abuse the battery as this may result in the exposure of the cell contents, which are corrosive.
  • Do not expose the battery to moisture or rain.
  • Keep battery away from fire or other sources of extreme heat. Do not incinerate. Exposure of battery to extreme heat may result in an explosion.

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 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.

Can I upgrade my Device's Battery to a newer Chemistry?   

Ni-Cd, Ni-MH 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.

Please refer to your owner's manual to find out which rechargeable battery types your particular device supports.

My new battery isn't charging. What's the deal?   

New batteries are shipped in a discharged condition and must charge 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.

How can I maximize battery performance?   
  • 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.
  • 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.

How are batteries rated?   

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.

How long do batteries last?   

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.
