I really like this charger to charge two of the 18650 batteries. Took around 5 hours to charge both of them. Seems to be very high quality.

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.

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.

Good way to start

All I need to keep my 3 lights happy. Not a lot of bells and whistles, just a good, basic charger. I believe Nitecore is a quality brand and I only have a few batteries, so I went with this charger.

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!

Not a good choice
May 4, 2019
I do like the form and weight of this charger but it's slow, really, really, really slow. A single new 18650 has been on charge for 3.5 hours now, two of them take eight. Right slot charges faster than the left. I will never buy another one of these, ever. Not worth the hassle of a return, sure it will be my fault some how. I'm over 50 and will not bother with crappy customer support on a cheap charger. Pick another option

I use a ton of gizmos that need batteries from most common household to 18650 and rCR123s. So rechargeable makes sence and they work fairly well over time to keep waste down and save $$. I got this to use on the exotic batteries to be a little more gentle and protect their value. But running standard nicad AA, I right away noted additional testable voltage that boosted all my charges equivalent to fresh Doracell and such. These last considerably longer in the field and I’ve seen no life decrease at all on my sets. My only regret is I do enough of these that I likely should have got a D4! I gave the handful of other chargers I owned to Goodwill!

I recently bought the nitecore Digicharger D2 2 channel charger. My 3rd order from BATTERY JUNCTION. I have tried the 18650 batteries in it, Ive tried AAA batteries, Ive tried AAA. Every battery Ive tried in this charger works flawlessly. It shows you in a digital flashing graph where your batteries are in the charging cycle. It also shows you how much mah is being fed to them and the total charge. With the 18650's as most people know it doesn't charge them to 3.7 volts, it charges them to 4.2 volts, so no panic is needed when you see them continuing to charge above 3.7 volts. It seems to be a little slow at charging but then again that's what a trickle charger does. This charger also tells you when it finished charging and will stop charging when it reaches full capacity. It can also tell what KIND of batteries you pout in there. Don't know HOW it does it but it does. I bought the 12 volt DC adapter for it ( its like $ 6 ). I tried the charger in my truck, works great. I can now charge my batteries while on the road, on camping trip. I will also likely be able to charge them off my solar panel. You cant really go wrong, for $30, you'll have a charger that can charge batteries by AC or DC. Simple easy to use. It also will tell you when you have a bad cell, it wont charge it. With these batteries whatever they may be Id advise don't waste your time. If this thing cant charge it, it belongs in battery recycle bin. I had a AA battery wouldn't charge it and now it can go into the used battery box at work. Im in the " GREAT WHITE NORTH " ( Canada ) and from time of order till its in my hand is like 6 days. good day eh

D2 Charger
November 4, 2016
Great charger. Only problem is that I screwed up. I just bought the D2 charger and it only does 2 batteries at a time. I should have gotten the D4 charger that does 4 batteries at a time. Now all I have to do is sell this to someone so I can get the D4 instead. The charger has doone a great job of charging all of my AA/AAA batteries. And, with 12 vdc capability I can take it on the road. Good job Nitecore !!

I am now really in LOVE with this charger. When I saw it I liked the look of the NITECORE Digicharger D2 and now when I use it, I REALLY LOVE IT!!! It charges ALL my rechargeable batteries I use and I get to see and monitor what is happening. I will now stick to NITECORE products and BatteryJunction.Com always for my battery and flashlight needs.

Nitecore D2, great feature set
March 28, 2015
After topping off three 18650's just to see how it worked, I am quite pleased. This charger gives more info than any charger I've ever owned by a considerable margin and seems well-conceived in every way. I really like it. Flexible: handles many battery types. Informative: reads out charging current, elapsed charging time, and voltage, independently for each slot (user selected). Nice looking. Good price. It can reportedly be dimmed for night time use when indicator lights would be annoying. It can charge LiFePO4 batteries too, but requires that the user select that mode. Li-Ion, NiMH and NiCad (perish the thought) are automatically detected and adapted to. There is a slower-charging option for use with smaller batteries (AAA's), I gather. I've had chargers which were for AA NiMH which offered slow and fast charging, with slow being better for the batteries. This D2 seems different in that respect, with one recommended charging rate for non-AAA batteries. I'm not sure whether the slow charging mode might have any significant benefit for larger-than-AAA sizes, but I don't think so.

This charger appears well-made. The display gives good info. I like being able to charge a single battery and not have to charge in pairs. Unit does not get hot and barely gets warm. It's definitely not a quick-charger by any means. 18650 batteries are a bit tight-fitting. Pretty idiot-proof though.

January 4, 2015
So far so good. I loved my Nitecore MT26 flashlight (now discontinued) until it died after only two years. That experience has made me leery of the Nitecore brand. Regardless, the charger functions as advertised and otherwise works well. It displays battery voltage accurately as verified by a multi-meter; does not heat up when in use; shows the amount of charge current and elapsed charge time. It has a nocturnal mode that turns off the display panel illumination; charges each battery independently reducing the input current as the battery comes up to charge shutting down automatically. Tests cells prior to beginning the charge cycle and detects a faulty / damaged cell, reverse polarity etc.

Works great on the li-ion 18650 batteries. I really like the display because it shows all of the information you need and more. Truly a universal charger. I have tried NiMH AA and AAA batteries. As soon as you put a battery in, the display tells you what type of battery is installed and charges accordingly. I really like this charger and have bought three of them, two for me one for a friend.
ProsLike display all the information you need can't beat the price when on sale
