Great charger with fantastic features


I purchased this charger to charge a selection of batteries I own, which range for Ni-mh AAA, AA, to Li-ion 18650 protected cells. This has to be the most detailed and information rich charger I have ever used. The display is excellent and is very clear to see and read, and it will dim in brightness after a few minutes of no buttons been pressed. The screen shows lots of information about the battery, charging status, charging progress, battery resistance (which I will describe later in this review). I really like the ability to alter the charging current, as it's said that charging Li-on cells with a high charging current can shorten its cycle life, so what I tend to do if I am charging my Li-on cells of an evening, I will put them on charge when I go to bed and choose a 1000 mA charging current, rather than the 2000+ what the charger defaults to for its detection of the 18650 cells in question. I do this for two reasons; one is I will be asleep for around 8 hours, so I do not need them to charge fast, and two is; it is said that charging on a lower charging current, will not shorten the cells life as much as charging on a higher charging current. It is also possible to charge some of the Li-on cells up with a maximum of 3000 mA charging current, so this would be ideal if you were in a hurry for your batteries, as the higher the charging current, the faster the batteries will charge. The display is split up into three sections: Top left is charging mode. This tells you battery type (Li-on, Ni-MH, Ni-CD, Li-FE), voltage type of the selected battery. Bottom is the charging channels. This tells you the selected battery channel (indicated by a line going off of it on the right to either 1, 2, 3, 4) a series of five segments for each channel, which flash as the channel is getting charged, and progressing from one segment on a low battery to a steady five segment when the battery in that channel is fully charged. Top right is channel status. This shows lots of useful information about the battery. From the current charging mA, the amount of mAh the battery has had put in it and also in this instance the charging time (when a channel is fully charged, the channel stops charging and you can see the total time it has taken to charge it to full). You can also select the charging current for the selected channel, and also you are able to individually select the charging current for the other channels too. I find this charging current option is really handy for when I am charging my Li-on batteries overnight, and don't require the fastest charging, and also charging Li-on batteries at a lower charging current, can (from what I've read) increase their charging cycle life. Also in the charging status, is shown the battery's internal resistance, which when the internal resistance is below 250mΩ, the lcd screen will indicate good when it is above 250mΩ, the lcd screen will show poor to indicate Battery Status. I have to say I cannot recommend in taking too much notice of this feature and also to the accuracy of this particular feature, as the various batteries I charged showed wild fluctuations in the readings. For example, if I put the battery in channel 1 and noted the resistance figure, and then removed the battery and put it into channel 2, or doing it with the other channels too, or even removing the battery and then putting it back into the same channel again, it would report differences in the figures of sometimes 200 or more from either the channel it had been in previously, or even when removing the battery and putting it back into the same channel. Also I will point out that the Li-on cells I put in did this (the Li-on cells were new and they were out of the TM28 that I had gotten days before) and also the Ni-MH AAA, AA which range from 6-12 months old did this also. My advice is, take the information provided from the feature with a pinch of salt, as I feel its not a reliable feature. I looked


Excellent charger. Great quality and interface and charges quickly.


A very tight squeeze to get 21700 batteries to fit. Noisiest charger ever- normally have mine next to the bed but have to leave this thing unplugged over night because it screeches constantly! Otherwise usual excellent nitecore quality.



Great product!




Excellent battery charger. One charger for all my needs. Genuine product. Would recommend.


The Nitecore SC4 is a four bay charger with a total output of 6A. The charger is compatible with a huge range of batteries and has been optimised for IMR cells.

Per bay the maximum charging current is 3A, providing extremely fast and efficient charging. As an example, it would only take 55 minutes to charge a 3500mAh 18650 IMR battery to 80%. 

The SC4 charger features an LCD screen with MVA technology to display real time information on the charging status. Press the 'V' button on the charger to display battery status, charging status, internal resistance, charging current and charging time. For multiple charging demands, the charging modes are manually selectable. To do this, press and hold the 'C' button to choose charging voltage (3.7V/4.2V/4.3V) and charging current (300mA-3000mA).

The smart charger automatically detects the battery type and capacity when inserted, in order to select the appropriate charging current. The batteries in bays one and two can be selected to charge in priority.

The Nitecore SC4 is able to recover depleted IMR batteries. Upon insertion of a 0V IMR battery, the LCD display will blink to indicate that it is non-rechargeable. In this instance, press the 'C' and 'V' button simultaneously to enter recover mode. If the battery fails to be recovered after serveral attempts, Nitecore recommends that the battery is abandoned.

The SC4 charger is compatible with the following Li-ion/IMR/LiFePO4 batteries: 10440, 10500, 12340, 12500, 12650, 13450, 13500, 13650, 14350, 14430, 14500, 14650, 16500, 16340 (RCR123), 16650, 17350, 17500, 17650, 17670, 18350, 18490, 18500, 18650, 22500, 22650, 25500, 26500, 26650. In addition, the following NiMH (NiCd) cells can be used: AA, AAA, AAAA, C and D.

The Nitecore charger comes with a UK 3 pin plug.
