D800 battery charger
« on: February 18, 2019, 09:59:51 »
With my D800 I received an MH-25 charger.

I am considering additional batteries for longer trips, I have yet to completely discharge the battery using it locally.  I only have one EN-EL15 battery which came with the D800.  The only genuine EN-EL15 battery I can find from mainstream  suppliers is the updated EN-EL15B battery which is supplied for the D850 and Z's.

My question is, will I be able to charge an EN-EL15B battery with an MH-25 charger.  All the specifications I can find say it needs an MH-25a charger.  I don't really want to spend £70 or £140 on batteries to find I also need the newer charger too.

Alternatively is there an aftermarket, non genuine supplier anybody can recommend, I do want something reliable and with maximum genuine capacity.  I am very impressed with my EN-EL15 battery even in cool mildly frosty conditions.  400 exposures and still going while the D3 with freshly charged aftermarket batteries died at ~ 180 exposures.

You will  be able to charge the EN-EL15B with your MH-25 charger. However, it might not be charged to the fullest capacity.

I do have a surplus of the MH-25a so can bring one extra with me to Scotland in May. It'll be yours for the taking.

After Birnas generos offer, it might not be necessary to tell about the Nitecore UNK1, which charges both D800 and Df batteries from a normal USB charger. It is very small much smaller than Nikons, got the tip about it from either Jakov or Jan Anne. I bought it from England ;)

Interesting ! Seems flat enough for my trips with the iPad and Df. Wonder about the charging time versus the Nikon one ?

It is slower, but it has a display that tell how much it has charged. So if in need, one can stop the charging at 90% and actually know it is 90%, at least if one know the charging curve (it display the voltage, not %).
There is no illusion, it just looks that way.

That is a very kind offer Birna, many thanks.  I think I understand now that the latter charger can push a tiny bit more charge into the newer batteries, which might just help one day.

If it's USB that would be extremely useful, since I have a variety of USB outlets in the car for charging and accessories power.

I will check it out.

Asle, thanks for the photo, very helpful.

The power of the internet!

This morning I received a small parcel, containing an EN-EL15 battery!

Eric, good friend of mine from Kings Lynn, here in the UK read this thread and sent me a surplus battery which he no longer needs, AMAZING!  Thank you Eric.

I have the Nitecore UNK2 and like the name it can handle 2 batteries at the same time (although one after each other).
It works with my EN-EL15A/B batteries and has the same size as the UNK1 model.
