Loading and Removing the Battery Pack
Your Handheld Terminal uses two types of battery: a battery pack and a memory
backup battery.
The battery pack is used to power normal operations and to store data, while the
memory backup battery provides the power required to maintain memory contents
when the battery pack power is unable to supply power for some reason.
The operating power is supplied by a battery pack. You can choose between a battery
pack
(HA-F20BAT) and a large-capacity battery pack (HA-F21LBAT).
The backup battery is installed inside of the Handheld Terminal.
This guide uses the following terms to refer to the batteries.
Battery Pack: Rechargeable battery pack (HA-F20BAT or HA-F21LBAT) for
normal operations and data storage
Backup Battery: Built-in battery for memory backup
When the battery pack power goes low, immediately charge it or replace it with a
charged battery pack.
You can use the Dual Battery Charger, the Cradle-type Battery Charger, the Cradle-type
Dual Battery Charger, the USB Cradle, or Ethernet Cradle to charge a battery pack. See
the sections of this guide that cover the Dual Battery Charger, the Cradle-type Battery
Charger, the Cradle-type Dual Battery Charger, the USB Cradle, and the Ethernet
Cradle for information about how to use them for charging.
Important!
Always keep backup copies of all important data!
The battery pack powers normal operation and also provides power required to
•
maintain memory contents, while the backup battery provides backup power to
maintain memory contents. Because of this, you should not remove the battery
pack if the backup battery is dead. Removing the battery pack while the backup
battery is dead causes data in the memory to be corrupted or lost. Note that
once data is lost it cannot be recovered. Always keep separate backup copies of
all important data.
The charge of a battery pack when you purchase it may be depleted due to
•
testing at the factory or natural discharge during shipment and storage. Be sure
to charge the battery pack before you use it.
The life of a battery pack is limited, and charging a battery pack causes it to
•
gradually lose its ability to maintain the charge. If your battery pack seems to
require charging very frequently, it probably means it is time to purchase a new one.
If a battery pack is used past the end of its service life, it may swell up in size. In
•
such a case, replace the battery pack with a new one.
When the battery pack is attached, it takes 30 minutes for the backup battery to
•
obtain enough charge for maintaining memory (RAM) contents for 10 minutes.
It takes two days for the backup battery to achieve a full charge.
