![]() I see as the only risk, that you miss out on a few extra mAh's of charge.You will need a USB-C cord with a 5-volt charging block. ![]() Because it can take more charge and perhaps more volts. ![]() If your older batteries survived whatever charger you used, so will the new one. The peak charge voltage should be the same but just take a bit longer. So does the new "c" type battery fit in the older less powerful chargers then? I'm all for a slower charger that does not get the battery so warm. The battery gets quite warm and I usually pull the plug early, finding it charged to a pretty high level long before you'd think. This is why manufacturers comes out with new improved types. The Li-ion chemistries (there are at least 5 main ones) are still being improved towards higher safe voltages/charges. I trust Nikon in this, but still like to charge batteries outside the camera. So the charger cuts out at a conservative safe voltage/charge. Oh and the Boeing dreamliner had a similar story. Too much voltage/charge poses a fire hazard, there was a Samsung mobile where they had become abit to greedy. For the same battery, higher voltage means more charge. Yes, and as you said the End of Charge voltage of Li-ion is variable. Just keep an eye on the battery indicator and the one but last item of the set up menu (the wrench): "battery info" for awhile. If you like experimenting, charge it first with your existing charger, pop it in the camera, connect the USB and see if it adds an appreciable amount before the orange charging light on the camera extinguishes. I see as the only risk, that you miss out on a few extra mAh's of charge. Note that none of this has anything to do with the capacity in mAh. My thought is that the newest charger might charge at a slightly faster rate to keep charging times down to normal.įor Li-Ion batteries the nominal voltage is 3.6 V/cell, max charge voltage is 4.1, best storage voltage is 3.7, and the minimum discharge voltage is 2.9 - 3.2V. The peak charging voltage is determined by the battery chemistry which is Li-Ion in this case I think, and not the capacity of the battery in mAh. Your older batteries are are rated for a bit less mAh charge, and perhaps a bit lower voltage once charged then the new one. If you are like me, you will be bored soon with peeling off the side of the camera for every charge. I have the ec-24 cable that came with the camera, so I am giving that a try. Takes a long time though (= overnight with my laptop). I used a random USB-C cable from my computer traveling light, did not know of a special cable. If I had to buy the 25a, having a 25, I would just try it, assuming I just loose a few mAh's and perhaps gaining some service life. My 2.5 yr old Z7 (first batch) already came with a 25a, so assume all Z's, except Z50 got that one. The c is the only one that needs the 25a, the difference might be a slightly higher End of Charge voltage, to be sure of the stated mAh of charge. Secondly, I want to know if I am limited to this discontinued cable or can I use pretty much any standard cable with the appropriate USB connectors and link to a power bank, my vehicle's usb socket or a generic usb wall plug?Įdit: Nikon included a nice "manual" with the battery in several languages, but that only contains warnings and disclaimers. Firstly, it seems discontinued: I cannot find a store here in South Africa that has stock, and I notice B&H marked it discontinued, pretty much same with Amazon. (b) If I want to charge the battery in camera (I am aware with my camera it must be turned off), both Nikon and online dealers only mention the EH 7P power adapter. So I want to make sure, is the older charger safe for the new battery? The shop where I bought the battery, and seemingly most other dealers also mention the MH25, that I still have from my D800. (a) Nikon's site says I must charge it with the MH25a. Now I am a bit confused when I read about the charger and camera charging cable: I used my old D800 batteries with my Z7 up till now, as I bought it second hand without its original battery.Īt the spur of the moment I ordered an en-el15c in October and it suddenly arrived at my door today.
