Insert, Detect, and Charge

Nitecore just keeps the goodies coming. Introducing the D2 Digicharger from Nitecore, a two-bay, two channel battery charger. The sleek and informative charger is compatible with a wide array of battery sizes and chemistry. Capable of charging two batteries simultaneously, ranging from Lithium-Ion, LiFePO4, to NiMh, and NiCd chemistry, you don't have to worry, as the D2 Digicharger automatically detects the battery type and status before entering automatic charge mode (CC, CV, dV/dt). The D2 Digicharger also automatically detects battery power status and selects the appropriate voltage and charge mode, with the exception of LiFePO4. You will have to manually select LiFePO4. Also, gone are the days where you have to sit around and wait for the battery to finish charging, as an automatic power-off function will cut off the current when charging is complete.

Advanced Display

The D2 Digicharger is equipped with informative LCD display to give you vital information, right when you need it. The crystalline LCD display reveals the charging progress, battery type, voltage, charging current, and charging time in an easy-to-read and intuitive detail. Charging batteries has never been easier, with an awesome design, cutting edge features, and an informative display, the D2 Digicharger is the one charger to rule them all. The Digicharger is also available in a four-channel model. Features:

One Year Old, Still A Fantastic Charger
July 6, 2019
Nothing bad to say about this charger. I do HVAC for a living and excellent lighting is a must! I use an Olight M23 as my EDC and go to light for Initial system diagnosis at night and in dark spaces. No light is good if your power is inadequate, so I use the best! My batteries are all from batteryjunction.com. Klarus, Olight, and Tenergy. The D2 and my I2 have charged them repeatedly every day, and never fail to perform. The D2 has very specific features that I love, like the ability to drop the charge rate to 300ma, which is really getting the mileage out of my Tenergy NiMh AA and AAA batteries which run my actual headlamps. The display is excellent. Constantly showing the charge rate, time in charge, and current voltage of the battery being charged. Controls on side allow you to toggle easily through selecting each battery and setting your charge rate, etc. Quickly identifies type and voltage of battery to be charged and bar graph on display shows current percentages of charging battery. The only thing it doesn't do that my I2 does, is allow you to charge at 1amp, not a big deal to me though, as I have many recharged extras waiting in the wings. Like the header Says, "One year, and still a fantastic charger!"

The Nitecore Digicharger D2 2-Channel Smart Battery Charger for Li-ion, Ni-Cd, & NiMH Batteries
May 15, 2019
Thie charger did everything the manufacturer said it will. I have a half dozen or so batteries of mixed types (Li-ion, Ni-Cd and NiMH) at the product worked like a champ. It even indicated that one of my Li-ion batteries was defective.

Battery Junction.Com is definitely the place I'll be purchasing all of my batteries, chargers and flashlights from. Fair prices and great service.

Thank you Battery Junction!

Quick Charge of Lithium Ion Batteries
December 9, 2019
Four #18650 lithium ion batteries and a charger came with a flashlight. Charger lasted less than two years. Nitecore charger let me know that two of the batteries were no longer functional. Quickly recharged the remaining batteries. That Nitecore charger is capable of recharging batteries of several sizes as well as batteries made of different chemical compounds, has led me to consider additional tools and devices that utilize rechargeable batteries.

Happy with this
September 19, 2019
Moving all the way into rechargeable batteries for all of my nitecore headlights. The info is great and charges fast enough for me. No problems ever and being able to charge 2 at a time makes things easier than my old single charger.

This uses a standard plug, not a USB by the way.
