Verified Purchase
I bought this charger to replace all the different chargers that I had for lithium and NiMh batteries. This device has an really great LED readout of everything that happens during the charging process, and, also, the ability to control how to charge the smaller capacity batteries. The system automatically detects the battery and selects the optimal charging method for the battery (The only battery that has to be manually detected is LiFePO4 batteries which is done by using the mode switch). The backlight display is easy to turn off by simply holding the 'slot' switch down for one second for economical/nocturnal charging. The charger is designed well and very lightweight.

I did try charging four 18650 lithium batteries at the same time, and, on a scale of one to 10, (where 10 is extremely warm), it gets to be an 8. Nitecore has stated that they use fire retardant materials within the charger. My approach, just use the two center slots to charge, and you will find that the charger will not get as warm because the heat will dissipate more efficiently. The heat dissipation factor is also the other reason why I would recommend the D4 over the D2. In addition, it is much easier to remove them gently from the charger when there is only two in the charger compared to having all four slots occupied. The negative terminals have a stiff spring. The thermal build up is quite a bit when charging four of these batteries at a time, and I am not certain what the effects would be on the electronic components over the long run. I have not tried charging AA NiMh batteries in a group of four, but I imagine it probably will not get as warm due to capacity of AAs.

Overall, this is a really excellent charger if you are looking for one that covers all the different sizes and types of chargeable batteries. (Note: the maximum size for NiMh or NiCad is C size. This charger will not cover D size batteries). Nitecore did a really impressive job with its design and quality.
