Chapter 2 Using your J3500 Using the battery 53
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.
To swap a battery with a tablet PC containing one battery and a 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 J3500 battery” on page 52.
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 J3500 battery” on page 52.
• To determine which battery requires charging, see the procedure for checking battery
status from the battery itself on page 51.
Important: Use only Motion Computing J-Series batteries with the J3500 Tablet PC.
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, 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).
N
OTE: In storage, the batteries will self-discharge at a rate of 10% of the total capacity per month.
Disposing used batteries
A Lithium-ion (Li-ion) battery should be disposed at a hazardous materials recycling center
when it is no longer serviceable. Do not throw it in a waste receptacle because the battery
could be sent to a landfill.
