Batteries die before full discharge
on 21 June 2015
I have 4 of these and 3 other aftermarket LP-E6's which I use with a 5d MarkIII.
I buy them because they are cheap and keep the camera firing. However, I would swap all 7 for 2 official Canon LP-E6's.
When they last, they last absolutely fine. Their capacity is definitely less than the Canon LP-E6 but they offer sufficient power for their value. The problem lies in the fact that they don't always last to full discharge. Sometimes they cut off with the camera reading 30% remaining, sometimes with 50% and sometimes even as much as 70% and then the camera just dies. This isn't really that bad for the camera or anything, but it can be frustrating and sometimes spoil work. In photography situations it isn't the worst thing, as you may lose a couple of shots but it takes seconds to swap the battery. In film, it's far more of an issue, especially if you're shooting a lot of material. Battery unexpectedly dying during a take is immensely frustrating! (My solution, by the way, is to always use an A/C adapter when filming important stuff, or where this is impossible, using a fresh battery before a take and changing around 50%).
So yes. It's not amazing, but it's a quick and cheap battery that works
