Nitecore digicharger d2

The Nitecore D2 is a universal two-slot charger that automatically detects Li-ion, NiMH and NiCd batteries, with manual selection available for LiFePO4 cells. Each slot monitors and charges independently.

Key features

• Two independent charging slots – different battery types or states can be charged at the same time
• Automatic detection of battery chemistry and condition, selecting the correct charge mode (CC, CV, dV/dt)
• Integrated LCD display showing voltage, current and charging progress per slot
• Reverse polarity protection and automatic shut-off when charging completes

Specifications

• Input: AC 100–240V 50/60Hz, DC 12V
• Output: 4.2V / 3.7V / 1.48V (±1%)
• Charging current: 500mA × 2 slots (max)
• Compatible cells: Li-ion/IMR (10440 up to 26650), NiMH/NiCd (AA, AAA, AAAA, C)
• Dimensions: 143 × 74 × 36mm · Weight: 168g (without batteries)

FAQ

Can I charge two different battery sizes at once? Yes — each of the two slots detects and charges independently, so mixed sizes and chemistries are fine.

Does it support LiFePO4 batteries? Yes, though these require manual mode selection rather than the automatic detection used for Li-ion, NiMH and NiCd.

What happens when charging finishes? The D2 automatically stops current to each slot once that battery reaches full charge.
