Chapter 3 Using your Tablet PC 47
Hot Swapping the battery
You can hot-swap a battery while the tablet is on and running on battery power only if you
have a second battery to replace the battery that is low on power.
To swap a battery with a tablet containing a battery and battery bay cartridge (non-
functioning)
• If your tablet has a battery and battery bay cartridge (non-functioning) installed, remove
the battery bay cartridge and install the second battery. For information about removing
the battery, see “Removing and replacing the battery” on page 46.
To hot-swap a battery with a tablet containing two batteries
• If your tablet has two batteries installed, remove the battery with the lowest power and
install the charged battery in the other battery bay. For information about removing the
battery, see “Removing and replacing the battery” on page 46.
To determine which battery needs to be replaced, see “Checking battery power” on
page 43.
Important: Use only Motion Computing J-Series batteries with the J-Series Tablet PC.
Battery maintenance
To maximize the performance of the tablet batteries, 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 43.
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.
Disposing of used batteries
When Lithium-ion (Li-ion) batteries are no longer serviceable, the batteries should be sent
to a hazardous materials recycling center. Do not discard the batteries in a waste receptacle
because they could be sent to a landfill.
