My 1sur3 7D battery to recharge capacity when I check his state with my 7D. This does not however alter its autonomy but as a precaution I ordered these 2 batteries so as not to crash right in the journey ... I confirm most of the comments on these batteries, almost identical autonomy, no performance difference the housing, and 2 cheaper than a single barrel marked with it. I end up with 3 batteries and therefore folly to autonomy. The only downside, sometimes the pictures taken counter does not reset after change, it does not confuse me more than that ..
