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.

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.

WARNING:

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.

THE i4 IS RESTRICTED TO CHARGING Li-ion, IMR, Ni-MH AND

Battery Activation

The i4 is capable of activating depleted Li-ion batteries with protective circuit. After battery

installation, i4 will test and activate the battery before charging. When a battery is detected

as damaged, the three yellow indicator LEDs over the slot will flicker, and i4 terminates its

charging. Such damaged battery cannot be activated by i4.

NOTE: Nitecore does not recommend charging 0V (depleted) unprotected Li-ion batteries

with i4 and doing so can result in battery fire or explosion.
