Hot-swapping the battery

You can hot-swap a battery while the Tablet PC is on and running on battery power if you
have a second battery to replace the battery that is low on power.
To swap a battery with a Tablet PC containing a battery and battery bay cartridge
(non-functioning)
•
If your Tablet PC 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 44.
To hot-swap a battery with a Tablet PC containing two batteries
•
If your Tablet PC has two batteries installed, remove the battery with the lowest power
and install the charged battery. For information about removing the battery, see
"Removing and replacing the battery" on page 44.
To determine which battery needs to be replaced, see "Checking battery power" on
page 41.
Important:
Use only Motion Computing J-Series batteries with the J-Series Tablet PC.

Battery maintenance

To maximize the performance of the batteries, deplete each battery's charge level to less
than 10% every 30 days. To deplete the charge, use the computer on battery power.
You can use the battery icon in the notification area to check the status of the battery. For
more information, see "Checking battery power" on page 41.

Long-term battery storage

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) and removed from the Tablet PC.
Check the batteries every 90 days or so to determine the charge status. Try to keep the
batteries at a level between 20% and 40%. For optimum care, store the battery in a cool, dry
place. 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.
