Nitecore D2 Charger

Nitecore D2 Charger


The Nitecore D2 is a universal smart charger compatible with almost all cylindrical rechargeable batteries.This eliminates the need to own several chargers.
The D2 automatically detects the battery type and an intelligent charging circuitry selects the optimal charging mode for each of the two microcomputer-controlled charging slots. This then monitors and charges the batteries independently.
Furthermore, an integrated digital LCD screen clearly displays charging progress, voltage, current and time while an intelligent automatic power-off function terminates current when charging is complete.

Nitecore Digicharger D2 - A good and short review

Hello, this is a short review of the new Nitecore Digicharger D2. This is a 'one for all' charger that can be used to charge single cells of the most popular chemistries.

The unit itself has an IEC 60230 female C7 (figure of 8) AC connector that is very common. The unit will run on 12v DC and 110v - 220v AC power.

This charger automatically recognises the battery's chemistry and selects the appropriate charging mode, CC (Constant Current) and CV (Constant Voltage) for Lithium cells or dV/dT (Delta Volts / Delta Time) for charging Nickel cells.

There is a version called the D4 that costs £2 more which has 4 slots instead of 2. Do bear in mind that the D4 distributes the charging current across the other slots thereby leading to a longer charge completion time.

This charger will completely charge a ~2500mAh Ni-MH cell in ~2.5 hours. If fast charging is what you're looking for, there are 15 minute fast Ni-MH chargers out there cost around the same price as this one.

This 'one for all' charger has replaced 3 of my older specific chargers that I've shown in the video.

If you have any questions regarding the safety of charging, cell chemistry, charging methods, etc. please leave me a question in the comments section below and I will try to answer them.

There is also a 2nd part to this video which is more technical and includes a few demonstrations. This video can be viewed here:
