    Lightbulb Regenerating your dead Hasselblad H battery grips

    Hi Guys,

    this might be useful to everyone on a budget with an H camera. Here's my attempt to replace the dead battery in one of the grips that came with my H2.
    All you need is (not enough money for a new grip ) the battery housing, a battery cage that takes AA batteries and some Li-Ion batteries that have proper dimensions such as these:
    4 x 3.7V 1200mAh 14500 AA R6 Mignon Lithium Li-ion Regenerierbar Batterie Akku | eBay

    Battery cage: Batteriehalter kompakt, 2x Mignon AA mit Anschlusskabel | eBay - Increadible how cheap both things are...



    I think these images are pretty self-explanatory. Open the housing. Remove the battery but make sure to cut one wire at a time to avoid short circuiting the battery. Even if it's dead, there might still be some charge left. Connect the battery cage properly and and add two 3,7V Li-Ion batteries. Reinsert everything into the housing and seal it with the black piece of plastic. Before doing all this I checked the polarity with a volt meter. The positive terminal is the one that is close to the charger attachment (just connect red with red and black with black.. ).

    I'm sorry for the bad quality of the photos, I only had my cellphone at hand.

    The new battery grip works flawlessly. Like the specs of the batteries above suggest, it doesn't last as long as the original grip but nevertheless I get about 500 exposures out of it. It charges with the original charger and is lighter than the original grip.
    I suggest using this resurrected grip with an H1, H2 or H4X camera. It will also work with the H3D, H4D etc. but since these cameras have DBs without power supply the battery will be drained even faster. So I doubt it'll be worth the hassle.


    Cheers,

    What would happen if you used UltraFire 26650 3.7V 7800mAh Rechargeable Li-ion Battery?

    Well Ultrafire brand might not be the one to use but if you used a higher mAh rated battery would that give you better results. You can buy 4 of these for about $20. Somewhat less that the price of a new Hasselblad unit.

    Re: Regenerating your dead Hasselblad H battery grips

    I was thinking about doing the same with two of my h l-ion batteries.

    I found ( these batteries ) that are identical to the ones in the grip. A little bit more expensive than your method, but still about 1/10th the cost of a new grip in Canada.

    Re: Regenerating your dead Hasselblad H battery grips

    When I read about about this, I realised I had a few old H batteries which were a bit weak. So I ordered the cells from the tme.eu site shown above, but it took them 2 months to deliver... To make the story short: I go the cells yesterday and exchanged the parts in the H grips... works very well.

    It would make sense to reset the batteries after the exchange. To do that, take back, lens and viewfinder off; press menu and flash; put the grip in and switch the body on while still pressing menu and flash. You will hear a series of beeps when the controller in the grip is reset.

    To glue the parts backs: polystyrene glue appears to work fine. Put some glue on the tongue and sides and fit the top part in. Put the little oval piece last after having put a bit of glue through the hole. Get a clamp to hold everything together till the glue has set.

    Nice, I've been waiting for them to be in stock before I ordered some. I didn't want to wait months to get them in, thank you it looks like they have some in stock now.

    Re: Regenerating your dead Hasselblad H battery grips

    Excuse me, I don't visit this forum as frequently as I once did. However, I forgot to mention that it's important that you remove the golden bolt that tells the camera how much charge is left in the battery. If you replace the original cells the way I did, the camera won't know that the battery is actually fully charged and instead wants you to replace the grip with a fresh one.

    You can see the bolt I'm referring to in this image on top of the bottom "spike", right side :


    (Left side) Simply remove the four black screws that hold that black piece of plastic in place and you can remove the bolt:

    It won't work since the battery is way too huge to fit into the original grip. It's both too thick and too tall. The part number "26650" means it's a large cell, the 14500 is the largest that still fits (keep in mind you need at least two cells).

    Great info, thanks! Looks like these batteries have the chip that is also on the original cells already included. After I realized that I won't have any battery status with my solution I searched fo the exact same cells that were in the original grip. Turns out that they're quite commonly used in laptop batteries. So I got these and ended up soldering everything together myself. That was no fun at all...

    Next time I'll be buying these instead for sure.

    Re: Regenerating your dead Hasselblad H battery grips

    Darn......I was going to buy a couple of the suggested batteries from TME but the only shipping option to the US is air freight and they can't ship batteries by air. Does anyone know of a US source? I Googled the Panasonic part number and didn't find a source other than TME.
    Thanks,

    I am trying to make this happen so far I remove the gold bolt but it still come out replace your battery.( with my H3D39II)
    Anyone can advise? I am using aa3 size/3.7V/ 2400ma rechargeable batteries/ Yet, I notice you guys share "that" batteries 2s1P, but it does not ship to my area so I try the first idea which replace it with aa3 batteries. I will check the remote control li-ion one see if anythinig fit in.

    Even if you cannot find the battery pack with the two cells, you can probably find the individual cells: Panasonic 103450. Then, you will need to open the 2 cells pack in the grip and rebuild it with the new cells. It is more involved, but still considerably cheaper than buying a new grip. Then you keep the golden "bolt", of course.

    Alternatively, you can ask someone from Europe to order a pack for you and mail it.

    [QUOTE=pochen86;678534] I solved the problems. Not that difficult. Thank you. you may ask some Remote control or drone ppl they may help you with batteries revise as long as the size can fit in the case the problem will be solved

    Thank you for all these people here. the li-ion inside the grip now is an old version and rarely found or difficult to shipping out of EU.

    So how did you solve the problem? Do you have a manufacture Part# for a replacement battery?

    Hobbyking have a huge range of lithium packs, european, US and Asian warehouses. I used to get my packs for RC Car racing from them and they where always great quality.

    Just looked into Hobby King, ordered a this pack to test.

    Power specs are the same with a little bump in mAh. It's also a tad longer, but should still fit in the grip.

    Make it easy. go to ask some drone forum ask: if there are batteries which 2s1p 7.4-8.4V then you may get a 800ma one that work. yes shorter life circle but still can keep your H batteries alive

    These didn't fit. They did come overnight from HK so it's kinda a bummer. Trying Ebay ones now. THe quoted total shipping time is ~1 month.

    Re: Regenerating your dead Hasselblad H battery grips

    Can anyone suggest some good rechargeable battery CR123A for my Hasselblad H3dD grip?
    I have noticed that there are a lot of them but they are 3,7V rather than 3V.
    Is anyone using rechargeable 3,7v battery?
    Do they work fine without damage the camera?
    As far as I know I know the battery should be 3v.
    PLEASE HELP!!!!

    If you google Nikon F6 and CR123 you will find a lot of angst on the same subject. The F6 eats CR 123, well for a film camera it does, 15/18 rolls a set is common some get 30 but they may be shooting manual lenses and rewinding manually !!
    Many have tried rechargeables in the F6 with no issues on compatibility, I see no reason why this would not translate to Hasselblad.
    The problem is not the voltage it is the capacity. Standard disposable CR123 are 1400mAh, you will find that most CR123 rechargeables advertised are 400mAh rated. Panasonic had some 800mAh and some others advertise as rated more, rated being the word, they do not perform to that level in real life.

    Have you managed to replace the battery and tested the grip?
    What has been the result?

    Not yet, the ebay ones are estimated to arrive between next tuesday till april the 14th. I will be installing the new cells if the past fit test the day they arrive. I have two batteries that give about 50 shots before they go into slow mode, then 20 more before the camera shuts down.

    Re: Regenerating your dead Hasselblad H battery grips

    Thanks for the thoughts on power for H series cameras. These batteries are rated at 2000mah (http://www.amazon.com/2000mah-16340-..._detailpages00) , so I am hoping that they will work in the reserve grip to avoid anything involving a soldering iron. Has anyone had success using the CR123s? My used H3Dii came with only one battery and the reserve battery. Not ready to blow another $250 on a spare, so I am looking for ongoing solutions. Particularly ones that don't pose a risk of frying the electronics.

    Re: Regenerating your dead Hasselblad H battery grips

    Funny, I'm still working in this.
    The batteries I've ordered off ebay failed to get delivered.

    No more than ten min ago I was talking with the manufacturer of the original battery. unfortunatly i have have to have a " MOQ is at least 2K "

    I've ordered a similar battery that should have the same cell in it, it arrives tomorrow. If not I have some 14500 coming, and I'll just end up building the cell myself.


    Update:

    Received a battery that I suspected would work. I replaced the cells with some out of a Casio NP-100. It'll say it's charging, and will power on the camera. Now giving it a full charge to see how it goes.

    Yeah, can't comment on longevity of battery yet. It's been working better than the initial cells that were in the original battery at time of replacing.

    That sounds good! I'll pick one up and give it a try.
    Another question; can you read the amount of charge remaining on the grip LCD screen?
    Thanks again,

    You will have to take the cells out and replace the ones in grip. Not too challenging if you know how to solder.

    After the initial charge, ~16hours, I did a battery grip reset "menu + flash" and the charge would display on the camera as a normal battery.

    Re: Regenerating your dead Hasselblad H battery grips

    I ordered a couple of batteries and will be here next week. Any tips of how to remove the cells from the case? Utility knife, big hammer? :-)

    I used a utility knife and some spudgers for taking apart cell phones and other electronics. The cells are wrapped pretty well, so there isn't a lot to worry about as long as you're careful.

    FInally gave it some real gusto yesterday photographing part of a wedding with it. ~320exp, higher than normal screen on time, with a 12-15 10sec exposures and ended with 40% still remaining. (based on camera body readings)

    I'm excited to build my own pack now with the 14500's if I can figure out how to fit them and the board into the grip.

    I got these rechargeable batteries that seem to work okay. (http://www.amazon.com/dp/B00AT79YUG/...4928607&sr=1-4)

    I wanted something to have a backup since at this point I'm not ready to blow another $250 on a spare Hasselblad battery.

    This is probably be my last update on this.
    I ended up looking more into this. I was always iffy on using off-brand cells, even though the generic battery out of this worked.

    It was easier to re-cell with it then I thought so I took this advice ...

Then you keep the golden "bolt", of course.

    Alternatively, you can ask someone from Europe to order a pack for you and mail it.
    ... and ordered These 103450 cells.

    Just rebuilt them using the old dead battery out of the previous grip as a guide. Tested every joint and wire with a multimeter along the way. The first one is charging now, everything went as easy as before.

    Re: Regenerating your dead Hasselblad H battery grips

    Hello all!

    Thank you Max for sharing this information.
    As I run into a used Hasselblad H3D and was not sure about the battery, I opened it up and found (probably I have the new grip with 3.100mAh) 2 18650 Li-Ion cells.
    So I looked at the electronics and saw, that the loading logics are in the grip itself, it's a standard loading chip that takes up to 12V and shuts down the loading process when the batteries reach 8.4V (2 x 4.2V).
    From my RC carreer background I know that often the 2 cells drift apart from each other, one getting weaker and weaker with every loading.
    So happened to the vac cleaner of my mum, I opened recently, loaded every single cell separately and reassembled (like new)... it's using 18650 cells too, like in the grip of my Hasselbald.
    Reading thriugh the comments, I should get some 350-450 shots with some long exposures.
    As my battery seems to be quite new, I'll have no issues going to Paris for 3 days next weekend...

    If anyone is in need of getting batteries replaced in the grip, don't hesitate to contact me!
    Should end up beeing less than 70€ to replace with high capacity Samsung cells and 3.400mAh


    I have built up some seriuos skills in electronics as I recently opened my Sigma APO 500/4.5D HSM and some cables broke...

    Will post some pictures of the inside of the new grip and possible replacements, even thinking about building up a spare 2cell and just swap it, when the grip goes down...

    BR Mike

    Re: Regenerating your dead Hasselblad H battery grips

    Great thread. I wonder if anyone tried to modify the CR123 holder with LiIon batteries to make a regular one? Is this possible?

    The aging battery on my H3D runs out very quickly with the digital back, though when shooting film, it will shoot a few rolls. Interested in a low cost solution, preferably without having to cut open the H grip, and as I have the CR123 grip which is unused, was thinking of using it as a donor grip.

    I took a look to the CR123 possibilities first before opening my H3 grip.
    Forget it, if you want to have high capacity you can't go with CR123 rechargable ones.
    Open the grip and replace with high quality LiIon 3x00mAh

    Thanks, what I meant was use the CR123 grip as the donor chasis to put in the LiIon replacement battery so I don't have to cut up the original battery, and I have an unused CR123 grip.

    Re: Regenerating your dead Hasselblad H battery grips

    No, that wont work ... theres some electronic in the grip for charging and communication, without that I guess the cam will not power on ... but I'll give it a try, probably you wont be able to use the original charger and the camera wont show battery levels ... btw Im missing thit info on the top screen, need to check if this shows only when empty.

    Will upload some pictures today of the inside of my grip, a newer generation with more mAh than stated in the description.

    Re: Regenerating your dead Hasselblad H battery grips

    So ... after finding some time ... here is the comaprison of the 2 different grips available.
    I got an used one for 50Ç second hand ... want to work with the H3D22 on weddings, at least a second battery is a must have ... would love to add a second CF slot too

    Left is the newer one, right side the older version, although it seems there have been some updates, see connector to the small board.
    The new version is much easier to open, just use some smartphone tools or a guitar pick, make sure it's from your favourite band, although I think it will open up even with a less rocky background

    As you can also see, the new one is a tad bigger (somehow the lines were messed up when downsizing...sorry for that).
    So you can only update the inner parts by using 18650 cells for the new one and updating the old one to 18650 cells will be a problem, although electronics should handle it.
    BE AWARE THERE ARE ELECTRONICS ALSO ON THE BATTERY PACK UNDERNEATH THE SHRINK WRAPPING! YOU MUST MAKE SURE THE NEW BATTERY HAS THIS ELECTRONICS OR YOU JUST SWAP IT, THIS IS A SO CALLED BALANCER BOARD SO THE 2 CELLS STAY ON A SAME CHARGING LEVEL!
    The 1850mAh battery I received is still ok, I have tested it separately with my RC loader and balanced the 2 cells, let's see how long that will feed the sensor of the H3D.
    If this one ever dies, I'll try to update it with higher capacity cells, the maximum size for the cell is 50x36x22mm ... maybe a millimeter more in width will fit, height should not be more than 50mm ...

    Also the protection cover will not fit the other batteries, the small nipple is at a different position, changed from inside to outside... if you ever take into conmsideration to buy a cover only, make sure to get the right one.

    NEW version uses 18650 Li-Ion round cells, I'd say you should go with Samsung or Sanyo cells 3400-3600mAh capacity
    OLD version uses the rectangle shape Li-Ion, check with yourt local RC specialist or google, you need to get 2s Li-Ion cells, mine is filled with an Celltech - Celltech Sverige AB21HA,7.4V 1950mAh 14.43Wh

    --------------------------------

    Place for pictures .. why can't I upload files?? I downsized them and tried to upload ...

    Re: Regenerating your dead Hasselblad H battery grips

    Anyone know where to buy a dead H grip to try is out? Or anyone offering a re-celled grip?

    I just ordered 2x of the grips from used photo pro

    One was only $31 the other was $41. Got them for re-celling, but they seem to charge up good. I'll see how they last, but I already have replacement cells for them.
