36 Chapter 3 Using your Tablet PC
Swapping the battery
You can swap the standard battery while the system is on, with or without having the
Tablet PC plugged in to AC power.
To swap batteries
1. Put the computer in Hibernate or Standby mode (page 33).
• With Standby, the Tablet PC will maintain your system for up to 30 seconds while you
swap the battery. You may have less than 30 seconds if you have many applications
running.
• With Hibernate, you will have as long as you need to swap the battery.
2. Remove the battery (page 35).
3. Insert the new battery (page 36).
Important: Use only Motion Computing LE-Series batteries with the LE-Series Tablet PC.
Battery maintenance
To maximize the performance of the tablet’s primary battery or Extended Battery, deplete
each battery’s charge level to less than 10% every 30 days. To deplete the charge, install the
Battery on the tablet and use the tablet without AC power until the battery charge is
depleted to less than10%. Verify the status of your battery using the battery icon in the
notification area of your tablet desktop. See “Checking battery power” on page 34.
Long-term battery storage (not attached to tablet)
Do not store any batteries with a full charge; this can cause a permanent loss of charging
capacity. For long-term storage, the battery should be charged to a level between 20% and
40% (two contiguous LEDs illuminated) of a full charge. Stored batteries should be checked
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.
