    Great. I have a masters in Physics and my work involved a lot of circuit design. Voltage changes in the middle of an operation is hardly what we're talking about with 3rd party batteries. Also, all cameras have a number of voltage regulation circuits to handle that eventuality, including some additional ones before the data read/write blocks.

    Re: OMD Spare batteries

    FlyPenFly and Henning - before the walls get stinky from a pissing contest, you might be talking past each other...

    Batteries don't randomly alter their voltage and there are excellent regulation circuits in the cameras. The chances of a generic battery "glitching" its voltage is somewhere close to zero. Battery chemistry just doesn't work that way. If there is a quality concern with a generic lithium cell it is the number of cycles it will take and the risk of shorts/fires. It won't have a freaky output voltage, there is no way for it to over voltage the camera. It could run out of charge faster than expected though.

    On the flip side, estimating remaining charge, giving fair warning and cleanly shutting down often involves a combination of "smarts" in both the battery and the camera. The result can be the some generics on some cameras (the GH2 being a good example) can result in the camera losing power without warning at the end of the useful charge of the battery. So far a few E-M5 users have reported something similar with some generics but it hasn't been clear if it was just a "fast" shutdown with little warning or if the camera actually cut-out in mid-operation. If the battery dies without warning then yes it is possible to end up with a corrupted filesystem on an SD card. Typically this means losing your last image. For video though you may lose the entire video in progress.

    Re: OMD Spare batteries

    I just placed a forward order for some proper batteries . . . . . . . .

    I seem to have slipped a 75 f1.8 pre-order on too

    Worth mentioning that I've completely failed to run a battery flat in a day's shooting - you need to remember to recharge each evening, but that's not a deal breaker . . . . . . . . but maybe I'm more abstemious with my shooting than some people?

    You are completely correct that this is possible, and sorry to all that I fired off the last message as I did. We all have skills and backgrounds that others are unaware of, and these should never be used to 'trump' a post.

    Standard design in cameras today is though that a hard shut down is not allowed. In actuality, even with Li-Ion batteries the voltage (and power) doesn't drop to nothing from a 'full voltage' with zero gradient. Remaining power, even though no longer acceptable to the camera for LCD or shutter operation is used for a safe shut down. As I mentioned before, for there to be data corruption due to a battery, the cameras has to have a number of other issues; possibly production anomalies resulting in a defective camera. That a camera like the GH2 might get confused by poorly written firmware in a 3rd party battery is a possibility, although a faint one. Mine has never had a problem; on the other hand I've not tested EVERY 3rd party battery with it.

    I've used probably 50 3rd party batteries in the last 10 years with no issues; not even on the various late model Pansonics and Canons that have proved difficult with 3rd party battery manufacturers. With the money I've saved I'm more than halfway to a Leica MM. I'll keep on this path.

    I've ordered 4 batteries off ebay for the OM-D; I'll report how they work.

    I am using two batteries with one in the body and one in the grip. I have the camera set to use the grip battery first. I haven't made it to the camera starting to use the body battery yet. At the end of shooting I just charge the grip battery (and then don't need to remove the grip). Three batteries seems optimum to work this way I can't possibly run out of charge in a day.

    As for the 75 f1.8 I had no doubt that it would find its way to your home.

    Re: OMD Spare batteries

    I ran a generic out somewhere around 300 shots. I haven't run down the original but I haven't pushed it past 200 yet. I would rather have originals but I have a two week trip planned and originals are not available.

    Congratulations Henning . . . I don't think I've spent more than $200 on batteries in the last 10 years, (although I think I might have inadvertently stolen some from Leica ). Long ways to go before I can pay for even the strap on an MM!

    I certainly didn't SPEND that much on batteries, but if I had bought the 18 or so I've gotten since the M8 came out from Leica instead of $11 third party ones, I'd be down that much money. Various places here want $200 to $250 now per battery. :bang head:

    Most days a couple of batteries are enough, but some days I've gone through a dozen on 3 cameras.

    Re: OMD Spare batteries

    Hi,

    I received a 3-battery set with charger from China. They seem to perform correctly with regard to capacity.

    But, they are very difficult to take OUT of the grip ... no problem getting them in, and also no problem in the camera body ...

    Anybody else faced this ?

    Same here, Rafa. I put my Oly battery in the grip and use the generics in the body.

    Re: OMD Spare batteries

    Because you have to unscrew the grip to change the battery in the body, I'm using generics in the HLD-6 where they are easier to get at.
    And having battery priority on the PBH and the body battery as secondary i hope to avoid issues.
    I've also set the battery remaining warning at +1 to trigger the flashing alert at higher voltage.
    And crossed my fingers.

    Re: OMD Spare batteries

    Hurrah ! I've got hold of a genuine E-M5 spare battery !
    Well, I don't have it yet, but I'll pick it up tomorrow.


    All the best.

    I got a couple from the UK supplier ExPro, one was fine the other a tight fit in the grip. On examination I realised this was because of poor moulding tolerances so, the application of a little fine abrasive paper removed the high spots, now it fits as smooth as silk (no more than half a millimetre needed to be removed, it was that close)

    Re: OMD Spare batteries

    Yeah finally got my extra OMD battery yesterday from Cameraland in NY. I ordered it along with the camera back in late May when I got the camera the following week the battery was MIA. I didn't want to mess with anything reverse engineered thank you. So now I"m all set finally.

    Re: OMD Spare batteries

    Finally had to cancel my orders with B&H and J&R. I'm leaving on a month long trip next week so I ended up ordering the generics from bestbatt.com.

    Gotta have some backup.

    Re: OMD Spare batteries

    Same dilemma here. I ordered a pair from Blue Nook. They seem to take a charge and they fit well into both the camera and the grip. Having a second charger is actually not a bad thing, either...still wish Oly had better supply chain dynamics. I guess I should look on the bright side - they didn't recall the batteries that shipped with the cameras!

    I've been using non-OEM batteries for two weeks now ... no problems whatsoever. I actually see no reason to replace them with Oly batteries.

    The plug adapter from the iPad? Now that's clever.

    I still haven't received my spare OEM battery on order since early June, so I purchased two generics and a charger from BestBatt. They fit the body and the grip quite well and are working ok.

    Re: OMD Spare batteries

    My BestBatt batteries fit in the body, but are tight in the grip. I am going to have to sand them down a little.

    UPDATE: A few seconds with some 80 grit and 200 grit sandpaper solved the problem. The BestBatt batteries fit smoothly into the grip now.

    Yep, I bought a spare from [email protected] for a couple of dollars. I should point out that it doesn't fit flush against the wall, so if you had an old/loose socket there would be some risk of having the whole thing disconnect and in any case there is a very small bit of the blades exposed, so if you were leaving this around where small children could reach it I suppose there's a safety risk above and beyond the usual risks associated with children and electrical plugs. As long as you exercise a small amount of that uncommon common sense, it works brilliantly.

    I also purchased a pair of aftermarket batteries and the charger ("Wasabi"). They've been working great for the past two weeks, including a pretty heavy stint at the Olympics.

    Re: OMD Spare batteries

    As mentioned before, I ordered some third party batteries and am reporting on my experience.

    I've just come back from a three week trip, for which I fortunately received my order of 4 batteries and a charger in time. The package seems much like other third party offerings. Mine was from elect_stores on ebay for $37.88 with free shipping included.

    Some days I shot 1000 shots, with chimping and leaving the camera on the whole day so I maybe started with a mostly dead battery from the day before, and changed batteries three times during the day maximum. I also had the battery that came with the camera; so five in total. I noticed no difference in the performance of the batteries. State of charge was shown with the 3rd party batteries as well.

    I don't have the grip so I can't comment on that application.

    I won't pursue getting OE batteries.
