What do I need to know about the Mercury battery?
Mercury runs on a Lithium Ion battery with a charge that lasts approximately seven hours with average
use. It recharges when plugged into its AC Power Adapter. The battery fully recharges in approximately
four hours while plugged into the AC Power Adapter. Additional Mercury batteries as well as an optional
external battery charger are sold separately by Assistive Technology, Inc.
To preserve the life of your battery, charge and discharge it frequently (daily, if possible). Leaving it in the
Mercury with it always plugged in will shorten the battery’s life. If the battery will not be used for a long
period of time, store it below room temperature at less than a 50% charge. If you follow these guidelines,
your battery should last for several years.
Warning: You will lose all unsaved data if you
change the battery while Mercury is in Stand By
mode and no power adapter is connected. Be
sure to shut the system down or connect the AC
power adapter before changing the battery.
To remove the battery:
Handle the battery carefully. Do not drop,
puncture, disassemble, mutilate or incinerate it.
Never get batteries wet.
