why does the battery die so fast with these. I've had to change them twice now after about a 12 minute shoot.

What battery are you using? I couldn't find any of the alternatives, so I use the 6 AA batteries and did two 30-min video sessions without changing them. Hope this helps! Charlie Seymour Jr, http://CharlieTheMarketer.com/sample-videos

Are you using the NP-550 rechargeable? I haven't had any problem with them lasting at least an hour or so. I actually turned them both on and left them on till they died and they both lasted an hour. On the other hand when using 6-AA's (supplied with the kit) they went out in about 20 minutes. They are very cheap batteries.

I'm so glad that someone else is having this problem, I thought I was doing something wrong!! I'm not to happy with this because batteries are very pricey!! Sorry I have nothing good to say about the lights:(

Are you using the heavy duty cells that came with the lights? I suggest alkaline batteries..I used the batteries it came with and had no problems. Alkaline lasts longer. They don't drain a lot. Turn lamps off when not shooting, that helps. I'll bet its your power source. Blaise

They are close to AA size, but are actually bigger. They are 3.6v batteries, and AA batteries are 1.5v batteries. They aren't interchangeable and probably wouldn't fit. These aren't appropriate to use in your camera.If you are using regular alkaline batteries (non-rechargeable), then that would explain why your batteries die so quickly. NiMH rechargeable batteries last much longer. You should be able to find some good high-capacity ones on Amazon somewhere.

Brilliantly in my experience. Been using them for weddings, as primary batteries. I can't remember now, but I believe in my review I put a number on how many shots I got from them.I purchased them before I did the firmware update, and updated after my 1st or 2nd use, they still work wonderfully.The only thing I don't know if their longevity...I'm not positive these will last as long as OEM, but so far I have absolutely no indication that they won't.

I have experienced the exact same problem and ended up having to buy a new battery. I would stay away from this battery if I were you. It worked well for about a month and then it wouldn't do anything in my camera. A waste of money for sure

I have 2 of these to extend the battery life of my two Canon 580 EXII flashes when we are on location shoots. I only shoot with a t1i and have the battery grips on both my main and back-up camera so I can use two batteries. I have had the cameras last for 6 hrs without ever being turned off and have never had them drain a fully charged set of batteries.

You do not say for how long assume you do this till the battery dies which I have never done&lt; it should last a couple hours I have taken 30 to 40 pictures in a matter of 10 mins. and the battery did not drain so sorry but little help here I am satisfied with the normal charge life of these.

I charged them initially for about three hours. One of the batteries seems to take a charge overnight, but the other is pretty bad. I love the unit when it is working, but all too often, the battery goes dead without any warning. I've tried to get replacement batteries (thinking I may have a bad one), but can't find them anywhere. This is totally unacceptable! If anyone knows where to get replacements, please let me know.

I haven't really gauged how long the battery lasts; much depends on flash usage, video vs. stills, etc. But, the battery in my new camera out lasts its predecessor, and I don't even give battery life a second thought. If you're worried, get a second, back-up battery.

The manual and the reviews say that it should last twice that much...are you doing something else besides shooting?..I mean, like playing with the settings, reviewing every shot longer than usual...if you are only taking pics, it's doesn't seem right, although having an extra battery is always recommended..

I've used them for a time, worked great but my personal pair stopped holding a charge longer than 5-15. It was super random and I gave them another chance at a wedding last weekend and nope.I might just have a bad pair but its really weird as I've had these batteries just under 2 years where as my OEM battery is nearly perfect. Just letting people know the other side of the story.

I don't know if you are referring to the battery or the camera? I find the battery does not last long, which is why I bought this additional battery as back up. I keep it with me while I am photographing. If you review your photographs on the camera after you take them, it uses up a lot of battery power, so I do not do that. Depends upon how many photos you take. If I am out all day photographing, the battery might last for one day.

I have no problem with the batteries en-el14. Fully charged them before use. They fit in the camera's battery compartment well.L

I have had no problems with this battery. I shoot sports pictures. I typically take 200 to 300 at a time. This battery and the one that came with the camera have both preformed flawlessly. I have one in the camera and one fully charged in the bag. When I get home and edit the pictures before posting I also swap the batteries and recharge the battery I just removed from the camera. I have zero experience with using my SLR camera for video. Probably 400 pictures would be okay from my experience. If this is a replacement, and you typically take 400 - 800 in a one day shoot, Then your level of use is enough to warrant buying two batteries and feeling secure. Good Luck.

My batteries still haven't run out. I don't think they are though. They can be replaced if you find a pair of the same grade. Or buy the company replacement batteries for about 10 dollars.

I was very disappointed with these batteries performance wise. They last approximately 12 minutes for video after a full charge. I use them as my last resort emergency batts to be sure I don't miss something. Would recommend buy oem or another brand. Seriously.

Having purchased this battery, I reviewed it based on the fact that when I used it in my camera, occasionally during the shoot, the camera simply wouldn't fire. I'd then turn the camera off and then back on, shoot a few more frames, then same thing. I've since acquired another Canon brand battery, and retired this one to use as a "backup backup backup." After all, you never know, and if you truly run out all of your batteries and still need to shoot, having an unreliable battery is still better than having no battery at all. How long does the battery last? Can't say. . . got too frustrated with its unreliability to keep using it until it died. Sorry.
