Chapter 2 Using Your XSLATE R12 Tablet Removing and Replacing the Battery 47
Hot-swapping the Battery
Changing a tablet battery while the tablet is in use and running on battery power is called hot-
swapping. You can hot-swap a battery only if you have a second charged battery to replace the
battery that is low on power.
While hot-swapping the battery, notice the following behaviors:
• The tablet display gets dimmer. When the charged battery is in the tablet, the display
brightens again.
• The LED lights for the battery gauge turn off. When the charged battery is in the tablet,
the LED lights turn on again.
• The power button is disabled. (The power button is disabled at any time the tablet has no
battery and is not running on AC power through the power adapter.)
Important: You have one minute to hot-swap the battery. If you haven’t replaced the battery
within one minute, the XSLATE R12 goes into Sleep mode.
1. Remove the battery.
2. Insert the new battery.
Important: Use only XSLATE R12-Series batteries with the tablet.
Long-term Battery Storage
Don’t store any batteries with a full charge, because this can cause a permanent loss of charging
capacity. For long-term storage, ensure that the charge level is between 20% and 40% (two
contiguous LEDs illuminated), and remove the battery from the tablet. Check stored batteries
every 90 days to determine the charge status. If only one LED or no LED is illuminated, recharge
the batteries to a level between 20% and 40%.
For optimum care, store the battery in a cool, dry environment. Never expose the battery to
temperatures above 60ºC (140ºF).
NOTE: In storage, the batteries will self-discharge at a rate of 10% of the total capacity per
month.
Disposing of Used Batteries
A Lithium-ion (Li-ion) battery should be disposed of at a hazardous materials recycling center
when it is no longer serviceable. Don’t throw it in a waste receptacle, because the battery might
be put into landfill.
