2.1 Battery Info
Battery Precautions
CAUTION
1) Do not recharge the battery pack if it is already fully
charged. Doing so may cause the life of the battery pack to
shorten or the battery pack may be damaged.
2) After recharging the battery pack, disconnect it from the
charger. If the charger power is reset (turned ON after being
turned OFF), recharging will start again and the battery pack
will become overcharged.
3) Do not use the transceiver while charging the battery pack.
We recommend you switch the transceiver power OFF while
in charging.
4) Do not short the battery terminals or dispose of the battery
by fire.
5) Never attempt to remove the casing from the battery pack.
DANGER!
1) Do not disassemble or reconstruct battery!
The battery pack has a safety function and protection circuit
to avoid danger. If they suffer serious damage, the battery
may generate heat or smoke, rupture, or burst into flame.
2) Do not short-circuit the battery!
Do not join the + and - terminals using any form of metal
(such as a paperclip or wire). Do not carry or store the
battery pack in containers holding metal objects (such as
wires, chain-necklace or hairpins). If the battery pack is
43
short-circuited, excessive current will flow and the battery
may generate heat or smoke, rupture, or burst into flame. It
will also cause metal object to heat up.
3) Do not incinerate or apply heat the battery!
If the insulator is melted, the gas release vent or safety
function is damaged, or the electrolyte is ignited, the battery
may generate heat or smoke, rupture, or burst into flame.
4) Do not use or leave the battery near fires, stoves, or other
heat generators!
If the polymer separator is melted due to high temperature,
an internal short-circuit may occur in the individual cells and
the battery may generate heat or smoke, rupture, or burst
into flame.
5) Do not immerse the battery in water or get it wet by other
means!
If the battery's protection circuit is damaged, the battery may
charge at extreme current (or voltage) and an abnormal
chemical reaction may occur. The battery may generate heat
or smoke, rupture, or burst into flame.
6) Do not charge the battery near fires or under direct sunlight!
If the battery's protection circuit is damaged, the battery may
charge at extreme current (or voltage) and an abnormal
chemical reaction may occur. The battery may generate heat
or smoke, rupture, or burst into flame.
7) Use only the specified charger and observe charging
requirements!
If the battery is charged in unspecified conditions (under
high temperature over the regulated value, excessive high
voltage or current over regulated value, or with a remodeled
charger), it may overcharge or an abnormal chemical
reaction may occur. The battery may generate heat or
smoke, or burst into flame.
8) Do not pierce the battery with any object, strike with an
instrument, or step on it!
This may break or deform the battery, causing a short-
circuited. The battery may generate heat or smoke, rupture,
or burst into flame.
9) Do not jar or throw the battery!
An impact may cause the battery to leak, generate heat or
smoke, rupture, and/or burst into flame. If the battery's
protection circuit is damaged, the battery may charge at an
abnormal current (or voltage), and an abnormal chemical
reaction may occur. The battery may generate heat or
smoke, rupture, or burst into flame.
10) Do not use the battery pack if it is damaged in any way!
The battery may generate heat or smoke, rupture, or burst
into flame.
11) Do not solder directly onto the battery!
If the insulator is melted or the gas release vent or safety
function is damaged, the battery may generate heat or
smoke, rupture, or burst into flame.
12) Do not reverse the battery polarity (and terminals)!
When charging a reversed battery, an abnormal chemical
reaction may occur. In some cases, an unexpected large
amount of current may flow upon discharging. The battery
may generate heat or smoke, rupture, or burst into flame.
65
13) Do not reverse-charge or reverse-connect the battery!
The battery pack has positive and negative poles. If the
battery pack does not smoothly connect with a charger or
operating equipment, do not force it; check the polarity of the
battery. If the battery pack is reverse-connected to the
charger, it will be reverse-charged and an abnormal
chemical reaction may occur. The battery may generate heat
or smoke, rupture, or burst into flame.
14) Do not touch a ruptured and leaking battery!
If the electrolyte liquid from the battery gets into your eyes,
wash your eyes out with fresh water as soon as possible,
without rubbing your eyes. Go to the hospital immediately. If
left untreated, it may cause eye-problems.
WARNING
1) Do not charge the battery for longer than the specified time!
If the battery pack has not finished charging even after the
regulated time has passed, stop it. The battery may
generate heat or smoke, rupture, or burst into flame.
2) Do not place the battery pack into a microwave or high-
pressure container!
The battery may generate heat or smoke, rupture, or burst
into flame.
3) Keep ruptured and leaking battery packs away from fire!
If the battery pack is leaking (or the battery emits a bad
odor), immediately remove it from flammable areas.
Electrolyte leaking from battery can easily catch on fire and
cause the battery to generate smoke or burst into flame.
4) Do not use an abnormal battery!
If the battery pack emits a bad odor, appears to have
different coloring, is deformed, or seems abnormal for any
other reason, remove it from the charger or operating
equipment and do not use it. The battery may generate heat
or smoke, rupture, or burst into flame.
2.2 Battery Care Tips
The transceiver is equipped with a INTEK Li-ion/Ni-MH
Battery Pack, the following using tips of which can help you
to get the best battery performance and longest battery life.
1) Charge the new battery pack continuously for 4~7 hours
before its initial using, which ensures the maximum battery
capacity and best performance in using.
2) Charging the battery pack in non-INTEK equipments will
cause battery damage and the battery warranty invalid.
3) The battery pack can be charged while in the transceiver,
and to ensure it is fully charged it's recommended to charge
the battery pack with the transceiver turned off.
4) The ideal temperature to store the battery pack is 25
(room temperature). Charging the battery pack at a low
temperature (below 0 ) will cause electrolyte leakage and
damage to the battery pack.
5) Charging the battery pack at a high temperature (above
35 ) will cause decrease in battery discharge capacity and
affect the transceiver performance. The INTEK rapid
charger has a temperature sensor, which ensures the
battery is charged within the temperature range mentioned
87
above.
6) A new battery shows no significant life shortening even after
two-year storage. The new or used battery should be stored
in a cool and dry place.
7) If recharge the battery pack after long storage, you should
charge it continuously for 4~7 hours.
8) Do not leave the transceiver and battery in the charger when
not charging. Overlong charging will shorten the battery life.
(Please do not use the charger as the transceiver's
mounting bracket.)
9) Please use INTEK charger to ensure battery normal work
and prolong its life. The battery and charger are designed
under an integrated concept of power system.
2.3 Battery Recycling and Disposing
After the battery life expires, the Li-ion battery can be
recycled, however, the recycling facilities are not available
everywhere.
INTEK goes in for the recycling of all the rechargeable
batteries. For more details please contact your local
INTEK distributor.
