I have cannon d40 and does both batteries drain at same time or one at a time?

One at a time. I can typically go about a month to a month in a half without charging (I shoot daily and often forget to turn camera off between shoots, as well).

I believe they drain at the same time. The bad thing is that there is no indication when the batteries are going to die.

They are connected in a series so both batteries deplete equally at the same time.

I use the Nikon battery in the grip (EN-EL3e). The unit begins to use the Battery Pack battery first and when that is drained, it goes to the camera battery. Perhaps I'm just lucky but I manage to get quite a bit of use with the Nikon batteries and that counts the times when I lay the camera down and forget to turn it off for a few hours. I would use the Nikon battery if speed is not an issue (you can easily get 8 fps); the AAs, as far as I am concerned, is something that I would only use if I were away for an extended period of time or used the Nikon D300 continuously for many hours. You don't have to pack the charger (a hassel, especially with airport security) and, if needed, you can always find someplace that sells AA batteries so you will always have a charged batter pack.

Yes, Works fine with only one battery installed on either side. I did notice that the battery level indicator on my camera only showed 1/2 battery like it was half dead when in fact it is actually full, when using one battery. But works fine. NIKON D3100

I've heard that there are problems with off brand batteries but not with Nikon's. For a quick test, remove the battery cover and push down both batteries with your fingers to make sure that they are touching the terminals. While doing that, see if you can power it on. This probably will do nothing because this was a problem with some of the off brand ones but you can try it just to be sure.

Yes, only one at a time. The camera can charge a battery also when it is connected to power.

On my camera the power display works the same as when I use the original cannon battery, is shows when it's full and as it gets low towards empty. recently it seems to outlast the cannon battery.

Works great....but the one I bought was for my 40D. It doubles the battery power for longer shooting.I also have the same for my 20D and for the same reason.

2 batteries ~ I have been using mine every other week for 3 years and it still works great. I leave my camera on for at least 3 to 4 hours and the battery meter still shows full.

Actually, I've never noticed. I usually use two batteries with no problems. I do a lot of vertical shots and it's been great so far.

With any camera battery you should never over charge it. You can risk the chance of burning out the battery and cause it from not working again. This has happend to me before with the original GoPro battery. I'm not shure if the wasabi battery is differnent from the original battery GoPro makes. I charge them both at the same time and unplug it as soon as it is fully charged.

I bought it I wish I didn't. Charge the batteries but they loose the charge right away. I use regular batteries now. Tired of seeing that the batteries are exhausted. One night this summer those batteries were in my camera they lost charge. My Lens was sticking out had to wait to get home to put batteries in to close my Nikon Coolpix up. Just sharing what happen to me.

You have the extended life of two batteries. In fact, your camera will allow you to configure which one is used up first, and will show you how much power is left in each. The MB-D11 unit makes your camera significantly heavier and larger, but the additional power is even more helpful if you're shooting in a continuous mode [as in sporting event], or when it would be egregious to run out of power [as in a wedding]. I like it, and am glad I have it. I should also say that I ordered and returned another manufacturer's version of the MB-D11. It seemed flimsy to me, and was more complicated to assemble. Like most Nikon equipment, I'm not sorry I bought that Nikon quality.

Yes, that being said it doesn't happen very often because the batteries usually fail after a month, that coincides with a 32mb card being full. I have mine set to film all day on a 4 second delay, days are shorter in the fall so you'll get another week. Battery life varies considerable because their mass produced and temperatures effect them so much, I could write a lengthy dissertation on battery brands and models after using them in my 3 camera's, they are the ultimate battery testers!

Robert, I said I would get back with you after taking more pictures. I just hit photo number 30 since you asked and no...it is not flashing that I need new batteries. I use regular Energizers. Nothing special. I too think you may have a problem with the camera. Although, I have gone through a couple pair of batteries very quickly, and it occured to me that the store may have just sold me old batteries. Not all have experation dates on the packging. Good luck, I love the pictures I am getting, I hope you do to.

I think the D7100 battery grip only holds one and you also have the battery in the body of the camera which makes it two.

I have use both. My style is to start with the 2 LP-E6 batteries and when they drain I go to the 6 AA's. I have never been at a shoot so long where I have depleted both.

Ed, I'm not sure- Never tried or looked into it- I bought two batteries and a charger so that when one battery is run down, I just pop the other one in while hte first one is charging again. My feeling is that if you are goign to spend nearly $8,000 on z camera setup, then get the recommended batteries to go with it- they will last longer per charge, and I've noticed that usiung the 1DX in live view mode really drains hte batteries quick, especially if using the timer too- So I like to keep one battery always charged and ready to go
