Novicius, check this link out and there are loads more... https://www.ebay.co.uk/itm/MTEC-Kamera-Akku-Batterie-2400mAh-ersetzt-Nikon-EN-EL14-EN-EL4a-Battery-Pack/372215245138?hash=item56a9c1e952%3Ag%3AMfcAAOSwImRaeYsg&LH_PrefLoc=3&_sop=2&_sacat=0&_nkw=EN-EL4a+battery&_from=R40&rt=nc It really isn't worth the time, trouble or risk to rebuild your own batteries. I wouldn't do it again and I am off the scale when it comes to doing it myself to save a cent.

Robert, how did you get around the charge cycle counter? Were you able to reset the counter so that the camera sees it as New?

I didn't... I naively thought that doing a refresh charge with the MH22 would have done the trick... Wrong! I expect the more technically adept would have been able to access the eprom and re-set it but that's well outside my skill range/pay grade! I live in hope that it doesn't switch itself off. I am looking at this seller, have just enquired if they are 2200mAh or the 1800 as shown in the image. They are just down the road from me in Preston, so if I have any bother I can go knocking on their door. https://www.ebay.co.uk/itm/322321339566?ul_noapp=true The price is right, it may be the same product I bought from Germany a couple of years ago. They are doing OK apart from in severe cold. Well over 1000 exposures in normal temperature less than 200 exposures in -8C with 30 second exposures, no low ISO noise reduction and an interval of ~40 seconds between exposure releases.

Robert, better get a couple of extras in case you take on my D3S. It awaits you. I will bring to UK in September.

I think like RAM, you can never have too many batteries. I have always fitted the largest, heaviest duty battery I can, to all my cars, learnt that from my digger days on cold mornings.

Re-building your house would be nice but Eric has me booked for a bungalow refurb in Yorkshire this fall, maybe... And I am still not finished on my own house yet! What about a tent? Well,since my daughter has dropped the idea of camping , I can have hers , so I`m catered for  And Many Thanks for Your Informative article Robert , it is Appreciated. I have allready purchased four ( third party )new EN-EL4 last year, for a reasonable fee from two different vendors from Germany I think , so far they `ve been holding up well. But I do have several original Nikon EN-EL4 , those came with my secondhand purchased D3S and D3X , they`re on 2 and 3 , so in some time from now I will replace the cells with new ones. I hate to discard stuff that can get fixed , and having a background in electronics , a Refurb of something like putting in new cells should be overcomeable . Apart from the Fun of " doing it meself ", there are now cells with a Higher capacity....3400 mah would you believe,but those are rated at 3.6 volt,and the originals are at 3.7 volts. You having observed the Parallel coupling is Interesting , so with a difference of only 0,1 volt , I am tempted to get those High capacity cells. All I need now is to build a Lightning deflector on my daughter`s tent, any pointers ..???

I would avoid the 3400mAh cells for two reasons, firstly that is an exaggerated vendor claim, only achievable under special conditions and secondly I doubt the existing Nikon control units would be tolerant or work well with the the difference in Voltage. I would stick with known high quality cells from Samsung or I think, Panasonic. There are I believe only three manufacturers of cells apart from the unknown quality coming from China, I realise the cells I am getting will be Chinese but with complete batteries all the components will match, re-celling a Nikon brand battery will involve mixing unknowns. The original Nikon cells were Samsung I think I showed that in my thread from February. Anyway, good luck, just be careful, very careful. I understand the challenge aspect but in this case I think prudence is a big factor too, not to mention the economics!

The EN-EL4 is rated at 11.1V, the EN-EL18 is rated at 10.8V but an MH26, with an adaptor, can be used to charge an EN-EL4. To all intents and purposes an EN-EL4 and an EN-EL18 are electrically very similar, if not identical. I suspect the MH22 and MH26 are equally similar under the skin.

Yes, I am skeptical about vendor`s claims , on the other hand , lower voltage usually results in higher amps. There are reports about dodgy third party Batts. that do not deliver as promised, including my own experiences with 3rd.party EN-4 batts.( D1 series) , after only a few chargings they gave up..opened one up and saw what I believe t` be Nicads !!...replaced with Fujitsu white Nihm`s and All is well now. I may have been lucky with the 3rd.party EN-EL4`s I purchased last year,but can not get those anymore...so, another reason for having a go at it myself.

Yes, that`s what I thought, and as far as I can gather , Li-ions drop in Voltage like Nicads / Nihm`s /Alkalines , and Robert`s observation of Parallel coupling would only result in a difference of 0,1 V which would be negligible as I expect the electronics would incorporate a voltage regulator , unless I am utterly mistaken?? What are Your thoughts on this ?
