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
Newly Received Batteries
Due to current regulations regarding shipment of Lithium Ion batteries, received 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 the computer on batteries
alone.
Disconnected Batteries
To check a battery that is disconnected from the computer, press the battery button to activate
the fuel gauge (see Figure 7). The lowest indicator will flash when the battery is at 10% charge
or below. Because batteries will continue to self-discharge slightly even when disconnected,
DRS recommends you recharge your batteries as soon as possible after they reach the 20%
level (LED #1 on steady).
Ins ta lle d Batteries
When an installed battery’s charge drops below 10%, a warning message, similar to the one in
Figure 88 will appear on the screen. At this point, the battery is in a fully depleted charge state
(between 10% and 3%) and you risk having the computer shut down unexpectedly if you
continue normal operations beyond this point.
To avoid a sudden shutdown and possible data loss, you should recharge your batteries as
soon as you see the warning message, or replace them immediately with fresh batteries.
