Operating Instructions
Connect to power source: connect one end of the in-car charging cord/adapter into
the V2, and the other end into the cigarette lighter or power socket.
Battery installation: The V2 has 2 slots to charge rechargeable batteries of varied
sizes. Please make sure to insert batteries of supported types into both slots observing
the polarity marks on each slot. The charger will not function if the battery is installed
incorrectly. The 3 green LEDs above the slot will blink simultaneously to notify users the
error.
Charging tips: During normal charging, the green LEDs will blink to indicate the
charging progress; Upon charging completion, 3 LEDs will become steady; If the
charger detects any error all 3 LEDs will blink to notify users.
Smart charging: The V2 will choose appropriate charging currents based on its
intelligent detection of battery types and capacities. Manual charging current selection
is also available. The V2 is compatible with: 3.7V Li-ion rechargeable batteries as well
as 1.2V Ni-MH/Ni-Cd rechargeable batteries.
Default Charging Current
The default charging current is 1A. After fully charged, the voltage of Li-ion batteries is
4.2V±1% and the voltage of Ni-MH/Ni-Cd batteries is 1.48V±1%.
Selecting Charging Current
After power on, the V2 will automatically select 1A charging current. User can press
the function switch to cycle through "1A-2A-3A". The blue LEDs on top of the V2 will
illuminate to indicate the present charging current:
1. 1 blue LED represents the charging current is 1A;
2. 2 blue LEDs represent the charging current is 2A;
3. 3 blue LEDs represent the charging current is 3A.
NOTE:
1. When the power supply is insufficient, or the batteries are near full, the V2 will
automatically lower the charging current while the blue LED is still showing the
original status.
2. For Li-ion, Ni-MH and Ni-Cd batteries of small capacity, the selectable maximum
charging current is 2A; For other large capacity batteries, the maximum charging
current is 3A; If the length of the battery is more than 60mm (2.4''), the V2
automatically identifies it as a larger capacity battery.
3. If one of the slots is charging a small capacity battery or any Ni-MH and Ni-Cd
battery, the maximum charging current of the charger will be no more than 2A.
Battery Activation
The V2 is capable of activating some depleted Li-ion batteries with protection circuit.
After battery installation, the V2 will test and attempt to activate the battery before
charging. When a protected Li-ion battery can not be activated, the V2 will consider it
as damaged, the green LEDs over the slot will blink to urge an immediate termination
of charging.
Li-ion Battery Recovery
Upon insertion of a 0V IMR battery, all 3 green LEDs over the slot will blink together
to indicate that the battery is non-rechargeable. In this situation, press and hold the
function switch to enter recovery mode. One of the LEDs will go on to notify users. It is
recommended to discard the battery if it fails to be recovered after several attempts.
NOTE: When attempting to activate an IMR battery, reverse polarity protection is
temporarily disabled. Take exceptional care to ensure batteries are correctly inserted.
Failing to do so may result in fire and explosion.
Overtime Charging Protection
The V2 will calculate the charging time of the battery in each slot separately. If the
accumulated charging time exceeds ten hours, it will automatically terminate charging
and all the green LEDs will go on. This is to prevent possible overheat or even explosion
due to battery quality issue.
Anti-short Circuiting and Reverse Polarity
Protection
If a battery is inserted with its polarity reversed or is short-circuited, 3 LEDs above that
slot will blink to notify users.
PID (Proportion Integration Differentiation)
System
The PID system will automatically regulate the charging temperature within the safety
limit when charging in a large current.
USB Output
The V2 supports USB output during charging. The maximum output current is 2.1A.
Cautions
1. The charger is restricted to charging Li-ion, IMR, Ni-MH/Ni-Cd rechargeable
batteries only. Never use the charger with other types of batteries as this could
result in battery explosion, cracking or leaking, causing property damage and/or
personal injury.
2. The safe operation temperature for the charger is between -10~40°C, and the safe
storage temperature is -20~60°C.
3. Please only charge the compatible batteries stated in the specifications of this user
manual.
4. Please connect this charger to power supplies with the input voltage stated in the
specifications of the user manual. If the input voltage is too low or too high, it may
lead to malfunctions, or even a fire.
5. Observe polarity diagrams located on the charger. Always place the battery cells
with positive tip facing the top.
