Nitecore NEW I4 Intelligent 18650 26650 20700 21700 Battery Charger Description UK Nitecore New i4 2017 CR123A 26650 18650 AA/AAA Intellicharge Battery Charger Quad Battery Smart Charger with UK Mains Plug.

The Intellicharger Nitecore New i4 (2017), an upgraded edition of the i4 eu/ i4, is a charger with compatibility, efficiency and intelligence. It works with almost all types of rechargeable batteries, including 1.2V, 3.7V, 4.2V, 4.35V batteries, thus eliminating the need to own several chargers. The NEW i4 is able to charge the batteries twice as fast as the i4 (Max up to 1.5A ).

With the Active Current Distribution (ACD) Technology, the NEW i4 automatically identifies battery types and capacity, and applies an appropriate charging current based on automatic detection or manual setting. It can even restore your depleted IMR battery. With automatic detection of non-rechargeable batteries, safety is not a problem on the NEW i4. Additionally, yellow and red power/ charging status indicator lights could visibly indicate battery status and charging process. The Nitecore NEW i4: it's as simple as insert, detect and charge.

Operating Instructions

Power on: Connect the NEW i4 to an external power source (such as vehicle adaptor, power socket) with its charging cord.

Battery placement: Put one batteries in each independently-controlled slot according to the polar mark on the charger.

Battery identification: All Four LEDs indicators will be lit when Lithium batteries are placed in, two lower LEDs will be lit when Ni-MH batteries are placed in. Charging begins in two seconds.

Other features: The New i4 has reverse polarity protection and anti-short circuiting protection incorporated.

Smart charging: The NEW i4 adopts the appropriate charging currents based on battery types and capacities. Whilst the option to adjust the current is also available.

The NEW i4 is compatible with:

1) 3.7V Li-ion rechargeable batteries

2) 3.8V Li-ion rechargeable batteries

3) 1.2V Ni-MH/Ni-Cd rechargeable batteries

4) 3.2V LiFePO4 batteries

During the charging process, the three indicator LEDs indicate the batteries’ status.
