  • Is it Possible to Upgrade the Device's Battery to a newer Chemistry?

  • Maybe. 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 battery chemistry.

    Please refer to your manual to find out which rechargeable battery types the particular device supports or use our Battery Quick Finder Wizard to find all the compatible battery for your device. It will automatically list all of the battery types supported by the your specific device.

  • How can I maximize the performance of my battery?

  • There are several steps you can take to help you get maximum performance from your battery:

    Prevent the Memory Effect - Keep the 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 the 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 the portable device.

    Exercise the Battery - Do not leave the 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, store it in a clean, dry, cool place away from heat and metal objects. NiCad, NiMH and Li-Ion batteries will self-discharge during storage; remember to recharge the batteries before use.

    Sealed Lead Acid - (SLA) batteries must be kept at full charge during storage. This is usually achieved by using special trickle chargers. If you do not have a trickle charger, do not attempt to store SLA batteries for more than three months.
