Important Notices and Precautions
The manufacturer has made safety the first priority during the design stage.
To avoid potential mishaps, please obey the following notices:
Do not allow water, seawater or moisture to enter or leak into the battery. If
the safety mechanism within the battery becomes oxidized, oxidized the
battery may overcharge with abnormal electrical current and/or voltage so
that it may overheat, ignite and/or explode.
Do not place the battery near open flames or heating devices, such as
stoves. Exposure to excessive heat may cause damage to the resin case
and/or insulating materials, thus causing a short circuit within the battery
that may result in battery overheating, combustion, and/or explosion.
Charge the battery only with the exclusive 4-slot battery charger specified
(optionally provided) by iMotion. The use of an incorrect charger may result
in overheating, combustion and/or explosion of the battery.
Charging the battery with a modified charger may result in overheating,
combustion and/or explosion of the battery by abnormal chemical reaction
caused by incorrect polarity.
Do not directly connect the battery to an electrical power outlet not specified
by iMotion or an automobile’s cigarette lighter jack. Doing so may result in
overheating, combustion and/or explosion of the battery by over-current
and/or over-voltage.
Do not heat the battery or place it near a fire. Doing so may melt insulation
materials, damage the safety mechanism/equipment, and/or ignite the
electrolytic solution. There is a potential risk of battery overheating,
combustion, and/or explosion.
Do not reverse the connection of (+) and (-) electrodes of the battery.
Charging the battery in reverse polarity may produce an undesired chemical
reaction inside the battery cell, causing unexpected behavior during
discharging such as overheating, explosion, or fire.
Do not allow the battery’s (+) or (-) pole to come into contact with any metal.
In addition, do not carry or store the battery with metallic items, such as
necklaces and hairpins. Doing so may cause a short circuit of the battery
generating an over-current. There is the potential risk to overheat, ignite
and/or explode the battery or overheat the metallic items, such as

iWaylink Inc.
iMotion MP121 / MP131 User’s Manual 5
necklaces, hair pins etc.
Do not throw the battery or subject it to strong shock. If the safety
mechanism in the battery is damaged, the battery may be overcharged and,
consequently, an adverse chemical reaction may be generated in the
battery. There is a potential risk of battery overheating, combustion, and/or
explosion.
Do not pierce the battery with a pointed object, such as nail or awl, or strike
with a heavy object, such as a hammer, and take care not to step on the
battery. There is a potential risk of battery overheating, combustion, and/or
explosion caused by an internal short circuit.
Do not solder the battery directly. Doing so may melt the insulating materials
and/or damage the safety mechanism or safety equipment, resulting in
battery overheating, combustion, and/or explosion.
Do not disassemble and/or modify the battery. The battery contains safety
equipment and a safety mechanism to prevent danger. There is a potential
risk of overheating, combustion, and/or explosion caused by disassembly.
Do not charge the battery near open flames and/or under direct sunlight.
Charging the ambient temperature at 0°C ~ 40°C. Because exposure to high
temperatures triggers the operation of the safety mechanism, the battery
may not charge or may overcharge due to destruction of the safety
mechanism. There is a potential risk of overheating, combustion, and/or
explosion.
Do not expose the battery to high temperatures over 60°C, and do not use or
store it in a hot or humid place.
Danger of explosion if battery is incorrectly replaced. Replace only with the
equivalent type recommended by the manufacturer.
Dispose of used batteries according to the manufacturer’s instructions.
Only use with designated power supply adapter model.
Changes or modifications not expressly approved by the party responsible
for compliance could void the user's authority to operate the equipment.
