Intellicharger i4

User Manual

The Intellicharge i4 is a universal, automatic smart-charger compatible with
almost all types of rechargeable batteries thus eliminating the need to own
several chargers. The i4 is able to automatically identify Li-ion, Ni-MH and
Ni-Cd rechargeable batteries and apply an appropriate charging mode
(Constant Charge Current (CC), Constant Charge Voltage (CV) and Trickle
Charge). Each of the i4’s four microcomputer-controlled charging slots is
capable of monitoring and charging batteries independently. Additionally,
yellow and blue power/charging status indicator lights could visibly indicate
battery status and charging process. i4: The all-new highly advanced smart
charger. It’s as simple as insert, detect, and charge.

Operating instructions

1. Plug one end of the power cord or car charger adapter to the charger’s
power input. Plug the other end of the cord into a wall outlet or the cigarette
lighter receptacle in your vehicle. The blue power light and all yellow power
indicators will illuminate as the charger runs a quick self-test. The yellow
power indicators will turn off automatically once testing has completed.

2. The i4 features four charging slots, with each slot able to charge batteries
independently. Rechargeable batteries of differing chemistries and voltages
may be charged simultaneously using 1, 2, 3 or all 4 of the charging slots.

Note: The i4 is capable of charging 3.7v Li-ion rechargeable cells OR 1.2V,

Ni-MH/Ni-Cd rechargeable batteries only. See above for description of
battery sizes.

3. When inserting a battery ensure the positive and negative ends correspond
with the positive (+) and negative (-) symbols on the charger. Incorrectly
inserting the batteries will result in the reverse polarity circuit being
activated causing the charge status lights to blink rapidly. Should this occur
reposition the batteries to the correct polarity.

4. When charging batteries, three yellow power indicators in each slot will
display battery status and blink. When charging is complete the three
yellow power indicators will illuminate steadily without blinking.

Note: When four batteries are charged at the same time, each charging

slot will receive a maximum output current of 375mA. When one or two
batteries are charged, each slot will receive a maximum output current of
750mA.

Battery Activation

For every installed battery, the i4 will activate the battery by charging it for six
seconds at a low current. If zero voltage is detected, all three yellow power
indicators will blink quickly. If activation fails the first time, please remove and
reinstall the battery once again and activate for the second time.
Note: The i4 is not recommended for use with over-discharged (zero volt)
UNPROTECTED Li-ion batteries. Li-ion batteries without a protection circuit
can potentially cause a fire or explosion.

Overtime Prevention

The i4 is equipped with an advanced ‘overtime’ safety function. The i4 will
individually monitor the elapsed charging time for each battery slot and if a
particular slot exceeds 20 hours, the i4 will automatically power off the slot
and three yellow power indicators will stop blinking and illuminate steadily to
indicate completion of the charging process. This feature reduces the risk
caused by batteries of lesser quality.

Precautions

1. Nitecore strongly recommends that AAA, AAAA and 10440 Li-ion
batteries are not charged alone in the i4 charger. When using only one
charging slot, the i4's current automatically sets to 750mA, which
exceeds the maximum current range of most AAA, AAAA and 10440
Li-ion batteries. Failing to follow to this recommendation can result in
excess heat, battery damage or even explosion,causing property damage
and/or personal injury.

2. Due to the aforementioned reasons, it is recommended that a minimum of
two (2) AAA or 10440 rechargeable batteries are placed into the charging
slots together. When charging two batteries in the i4, be sure to always
place them in either slot 1 and 3 or slot 2 and 4.

3. When charging different battery types simultaneously (for example, li-ion
26650 and AAA), always ensure solid contact is made between both
sides of the battery and the charging slot’s metal contact points.

4. The i4 is restricted to charging Li-ion, IMR, Ni-MH and Ni-Cd
rechargeable batteries only. Never use the i4 for other types of batteries
as this could result in battery explosion, cracking or leaking, causing
property damage and/or personal injury.

5. The i4 should only be used indoors or inside a motor vehicle. Do not
expose it to water, high humidity, low or high ambient temperatures.

6. Do not disassemble or modify the charger.

7. Children under the age of 18 should be supervised by an adult when
using the i4.

8. The i4’s safe operating temperature is between 0℃--40℃.

9. Do not use or store the charger near open flames, direct sunlight, heating
devices or other high-temperature environments.
