Rechargeable Li-ion battery
• At the time of purchase, the rechargeable Li-ion battery is slightly
charged so that the operation of the scanner can be verified; however,
the rechargeable Li-ion battery should be fully charged via the USB port
before the scanner is used.
• If the scanner will not be used for a long period of time, remove the
rechargeable Li-ion battery from the scanner, and then store it in a
location where it is not exposed to static electricity, high humidity, or
high temperatures (temperatures between 59°F/15°C and 77°F/25°C
and 40% to 60% humidity are recommended). In order to maintain the
efficiency and life of the Li-ion rechargeable battery, charge it at least
every six months.
• If you notice anything unusual about the rechargeable Li-ion battery the
first time it is used, for example overheating or rust, DO NOT continue
to use the battery. Contact Brother customer service.
Tips on using the rechargeable Li-ion
battery
• Charge the rechargeable Li-ion battery before use. Do not use it before
it is charged.
• The rechargeable Li-ion battery charging can take place in 41°F-95°F
(5°C-35°C) environments. Charge the rechargeable Li-ion battery in an
environment in this temperature range. If the surrounding temperature
is out of this range, the rechargeable Li-ion battery will not be charged,
and the battery indicator will remain lit.
• If the scanner is used when both the rechargeable Li-ion battery is
installed and the scanner is connected to your computer, the battery
indicator may turn off and charging may stop even if the rechargeable
Li-ion battery has not been fully charged.
Rechargeable Li-ion battery
characteristics
Understanding the properties of the rechargeable Li-ion battery will allow you
to optimize its usage.
• Using or storing the rechargeable Li-ion battery in a location exposed
to high or low temperatures may accelerate its deterioration. In
particular, using a rechargeable Li-ion battery with a high charge (90%
or more) in a location exposed to high temperatures will considerably
accelerate battery deterioration.
• Using the scanner while the rechargeable Li-ion battery is installed and
charging may accelerate the battery’s deterioration. If using the
scanner when the rechargeable Li-ion battery is installed, disconnect
the USB cable.
• If the scanner will not be used for longer than one month, remove the
rechargeable Li-ion battery from the scanner when its charge is 50% or
less, and then store the battery in a cool place away from direct
sunlight.
• If the rechargeable Li-ion battery will not be used for a long period of
time, we recommend charging it every 6 months.
• If you touch a part of the scanner while the Li-ion battery is charging,
that part of the scanner may feel warm. This is normal, and the scanner
may be used safely. If the scanner becomes extremely hot, discontinue
use.
