The New i4 battery charger by Nitecore has wide range of compatibility and is capable of charging up to four battery cells at one time. Upgraded from its previous version, the New i4 comes with five new revolutionary features:
100% Charging Acceleration | Active current Distribution Technology | IMR Battery Restoration
Expanded Compatibility to Support 3.7V and 4.35V Batteries | Automatic Current Selection Based on Battery Capacity

Compatible with:
Li-ion/IMR/LiFeoPO4:
10340 | 10350 | 10440 | 10500
12340 | 12500 | 12650 | 13450
13500 | 13650 | 14430 | 14500
14650 | 16500 | 16340 | 16650
17500 | 17650 | 17670 | 18350
18490 | 18500 | 18650 | 22500
22650 | 25500 | 26500 | 26650
Flat-topped batteries: 18700 | 20700 | 21700
Ni-MH(NiCd):
AA | AAA | AAAA | C | D

The New i4 can charge up to 1.5A in one slot, which is 100% more than that on an old version of the i4 charger.

The ACD technology allows for dynamic distribution of the NEW i4's charging power. Capable of identifying a fully charged battery and diverting all of its outputting power to the next charging slot.

Compatible with 1.2V, 3.7V, 4.2V and 4.35V batteries. By simply pressing the "V" button, you can easily set the charging voltage of each independent slot.

You can press and hold both the "C" button and the "V" button to initiate IMR battery recovery, to restore a 0V depleted IMR battery.

For larger capacity batteries like 18650 and 26650 LI-ion batteries, press and hold the "C" button to activate 1500 mA fast charging. The New i4 can intelligently select the most appropriate charging current based on automatic battery capacity detection.

With extremely low internal resistance, IMR batteries may be overcharged and lead to safety issues. The New i4 incorporates an optimised IMR charging system that is able to monitor the entire charging process, ensuring the end voltage is always within safe limits.

The New i4 will immediately terminate charging and notify users with four LEDs turned on when a battery is installed backwards.

Each battery is monitored independently on the New i4 battery charger. When charging duration reaches 20 hours, the New i4 will automatically stop charging and display a fully charged status.

The New i4 is made to last with fire retardant and flame resistant PC materials, enhanced security and unyielding solidity.

Perfectly compatible with a car charger and a wall adapter.
