7D2 batteries

Does anyone use non-Canon batteries in this camera? If so, do they work well and which ones are they? I have several off-brand batteries for my T3i that work just as well as the Canon brand, but I can't seem to find any for the 7D2 that match the volts and mAh of the Canon brand.

Have you looked at Wasabi? $30 for two batteries and a charger.

I have the same batteries DGStinner linked to. They are better than Canon originals. I bought them for my 60D. I used them in my 60D and 7D, before I sold both. I currently use them in a 6D and 70D with no problems whatsoever. I'd buy them again, if the ones I have ever wear out.

Thanks, that's a great price. The Canon is 1865 mAh and the Wasabi is 2600 mAh. Does this matter?

That is mostly an advertising department sales gimmick. I find the Wasabis last longer than the original Canon batteries. Heck, even if they don't, you get 2 and a house/car charger for less than ONE Canon battery. Good deal.

It is an excellent deal. I haven't had any problem with the off-brands for my T3i. I was just concerned because the mAh doesn't match up and didn't know if this difference would damage my camera.

The mAh is the storage capacity of the battery. With the numbers listed the wasabi can store about 50% more power than the canon. Assuming the numbers are reasonably accurate you should get a lot more shots with the wasabi. The voltage would be the critical factor.

Thanks. I'm going to order these.

Yes the voltage is the critical value, that has to be correct for the camera (or other electronic) system to function correctly. The mAh rating is a rating of how much energy the battery can store, and then supply, in other words the capacity (not capacitance, that's something else entirely). Effectively a 2600mAh battery can supply 2600mA (or 2.6A) for one hour, while an 1865 mAh battery can only supply 1865mA for one hour. Of course usually the electronics is drawing much less than the rated load, so if the camera only draws 500mA that means the 2600mAh battery should last for 5hr 12min, while the 1865mAh will only deliver for 3hr 43min 48s. Well theoretically, it won't be that accurate in real life, but you get the idea. It allows you to work out how long something will last given the working current draw.

I am currently working on the control systems for some 12 volt powered clay pigeon traps, mounted on a trailer. The total current draw for the system, when everything is running is 63A, so we have to install a 120Ah sealed lead acid leisure battery to provide a decent run time, normally we would use a 60Ah battery for a single trap, running at around a max load of 24A, which would give nearly three hours of continuous use. The total load in the trailer means that we have to use some really heavy duty cable to run from the battery to the control panel, just to stop it overheating. The smaller cables might happily run at 85C, but the customer won't be very happy if they touch one and get burned, so we have to use a much higher rated cable to keep the temps down. The joys and worries of designing stuff . At least testing the systems out is a good excuse to get out the shotgun and do some shooting.

In use Wasabi batteries in both my 7D2 and 5D3. Getting an extra charger thrown in when you buy two batteries is also a nice bonus. You can never have too many chargers. I keep one in each bag, plus an extra one on the shelf for charging at home.

Yep, I've had issues with generic batteries giving me error codes in the past. But I've been happy with the Wasabi batteries in my 5D3, and they're supposed to be fully 7D2 compatible as well.

B&H included a Watson battery when I purchased my 7D2, and I rotate it with the Canon Batteries in an effort to use/recharge them all equally. There appears (six months down the road) to be no difference in performance at all.

I've had no problems with the generics I bought for my T3i other than the battery meter not working. They go without warning. But they last just as long as the Canon battery, so I can live with that. They aren't Wasabi. I don't know what brand they are because it isn't marked on the battery. I ordered these Wasabi batteries for my 7D2.

The issue is the chip in the battery. If it's not compatible with the camera, it'll give you an error message, no battery meter, etc.

I have some older STK's that are great batteries, but they work fine in my 60D, but give me error messages on my 5D3 (communication with the battery is irregular). After bypassing the message, they seem to work fine, but every battery has the same serial #, recharge status, etc.

I'm sure newer decoded STK's are as good as the Wasabi batteries.
