Mixed batteries in grip

Is it ok to combine battery brands in a battery grip? For example a OEM Canon battery with a Opteka 3rd party battery without issues down the line?

Thanks in advance...

I mixed batteries in my Rebel XT without any problems. Otherwise you could just use one battery at a time in the grip and use the other one as a reserve.

I have Canon battery and Opteka battery in my grip - no problem.

We mix Canon and no name batteries in our grips all the time. It's been about 5 years without any problems...

Thanks all....ordered the Opteka and this should provide plenty of back up power as well as some added balance once in the grip...

I have the original Canon battery and a Delkin e-film battery in my 40D and haven't had problems. All I did was make sure they were fairly close in their mAh ratings... The Canon is 1390mAh and the Delkin 1400mAh.

Presuming the batteries are compatible with the camera in the first place, it's no problem.

All the Canon consumer grips are designed to draw from the stronger battery first until it's equal to the weaker, then it alternates a few shots at a time between the two batteries to draw them down at the same rate.

So it doesn't matter if one battery is of greater MaH than the other. Even if one battery were totally drained, the grip would just draw from the fresh one.
