Loading and Removing the Battery Pack
Your Handheld Printer 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.
Use the battery pack (HA-G20BAT) as the main power source.
The backup battery is installed inside of the Handheld Printer Terminal.
This guide uses the following terms to refer to the batteries.
Battery Pack:
Rechargeable battery pack (HA-G20BAT) 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 USB Cradle,
the Ethernet Cradle, the Car Mounted-type Battery Charger, or the AC adaptor to charge
a battery pack installed in the terminal. See the relevant sections in this guide for the
respective options about how to use.
Important!
Always keep backup 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 backup 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.
If the backup battery is fully charged, it will maintain the contents of the
terminal's memory (RAM) for approximately 10 minutes when the main battery
pack is removed.
It takes 4 days with the main battery pack installed in the terminal for the
backup battery to be charged fully.
