Safety and Handling Considerations for Your Batteries
Please use the following safety rules when handling and using lithium-Ion batteries.
• Do not expose the batteries to very high temperatures such as an open flame.
• Do not short circuit the battery contacts or reverse their polarity.
• Do not let children play with the batteries.
• Do not crush, dent or allow any deformation of the batteries.
• Do not disassemble or open the batteries or try to alter or bypass the internal safety
circuits.
• Avoid exposing the batteries to wet or extremely humid conditions.
• Avoid exposing the batteries to electrostatic discharge.
• Avoid dropping the batteries.
• Do not use in, or connect the batteries to, any other devices.
• Do not allow batteries to remain discharged for more than 1 week
When to Charge a Battery
New Batteries
Due to current regulations regarding shipment of Lithium Ion batteries, your batteries will arrive
in a partially charged condition, typically with a maximum charge of 30%-50%. When you
receive new batteries, you should fully charge them prior to using them in a computer.
In-Service Batteries
The fuel gauge LEDs on the back of the ARMOR X10gx indicate the remaining charge of each
battery. At full charge, all five LEDs will be on steady and the amber battery status LED will be
on steady if external power is applied. If external power is off or disconnected, the battery status
LED will be off.
NOTE
When the lowest fuel gauge indicator begins to flash, the battery
charge is at 10% and the tablet could shut down prematurely,
resulting in the loss of any work in progress.
As the battery discharges, the LEDs will turn off from right to left. When a battery’s charge drops
below 10%, the 20% (far left) LED will start flashing. You will also receive a warning message
on the screen. At this point, the battery is in a fully depleted charge state (between 10% and
3%) and the computer could shut down unexpectedly.
To avoid a sudden shutdown and possible data loss, DRS recommends you recharge your
batteries as soon as they reach the 10% charge level, or replace them immediately with fresh
batteries.
