Rechargeable Li-ion Battery
Carefully observe the following precautions for the optional rechargeable Li-ion battery (hereafter,
referred to as “rechargeable battery”), otherwise heat or cracks may be produced, or leaking,
electrical short, explosion, smoke, fire, electric shock, or damage may result.
To charge the rechargeable battery, insert the rechargeable battery into the PocketJet
PJ-622/PJ-623/PJ-662/PJ-663, and then use the AC adapter/DC cable designed specifically for
this printer.
Do not disassemble or modify the rechargeable battery. The safety mechanisms and protection
circuitry within the rechargeable battery could become disabled.
Do not allow wires or other metal objects to come into contact with the terminals of the
rechargeable battery. Do not carry or store with metal objects such as necklaces or hairpins.
This could cause an electrical short, and could cause metal objects such as wires, necklaces,
or hairpins to overheat.
Do not dispose of the rechargeable battery in fire or intentionally overheat. This could cause the
internal insulation to melt, gas to be emitted, or safety mechanisms to fail. Additionally, the
electrolyte could catch fire.
Do not use or leave the rechargeable battery near fire, heaters, or other high temperature
(above 80C) locations.
Do not allow the rechargeable battery to come into contact with or to be immersed in regular or
salt water. The safety mechanisms and protection circuitry within the rechargeable battery could
become disabled.
Do not charge the rechargeable battery near a fire or in direct sunlight. This could cause the
protection circuitry which is designed to prevent danger due to high heat to activate, causing
either charging to stop, charging to occur under excessive current/voltage due to failure of the
protection circuitry, or abnormal chemical reaction within the rechargeable battery.
Only charge the rechargeable battery using the AC adapter/DC cable designed specifically for
this printer or in accordance with the specified charging parameters. Charging outside these
parameters (charging at higher than the recommended temperature, higher than the
recommended current/voltage, using a modified adapter, etc.) could overcharge the
rechargeable battery, charge the rechargeable battery at an abnormal current/voltage, or cause
an abnormal chemical reaction within the rechargeable battery.
Do not pierce the rechargeable battery with a nail, hit with a hammer, or step on the
rechargeable battery.
Do not subject the rechargeable battery to severe shocks or throw the rechargeable battery.
Damage to the rechargeable battery’s protection circuitry could cause the rechargeable battery
to be recharged at an abnormal current/voltage, or cause an abnormal chemical reaction within
the rechargeable battery.
Do not use the rechargeable battery if it is severely damaged or deformed.
Do not directly solder any connections to the rechargeable battery. This could cause internal
insulation to melt, gas to be emitted, or safety mechanisms to fail.
Do not use the rechargeable battery with the polarity (+) (-) reversed. Check the orientation of
the rechargeable battery before inserting it, and do not try to force the rechargeable battery into
the printer. Charging the rechargeable battery with the polarity reversed could cause an
abnormal chemical reaction within the rechargeable battery or abnormal current flow during
discharge.
Do not directly connect the rechargeable battery to a household or vehicle cigarette lighter
socket.
