Now, I have read reviews that say your camera wont be able to communicate with NON OEM batteries and you wont be able to see the battery life still left available - HOGWASH. I have owned Canon GL1's & GL2's, Sony VX2000's & VX2100's and NOW the NEW Canon XA10 and the XF100 and ALL of them work/operate/report and perform Perfectly fine with Wasabi Power Batteries.
I had pre-ordered my Canon XA10 back in January and waited til it arrived before purchasing additional batteries. The Canon BP 808 that came with the camera is a tiny lil battery that at 850 mAh does not last very long (maybe 1.5 to 2 hrs) BUT this BP 827 Wasabi Power replacement battery is a MUST have. At 3 times the size and 3000 mAh it runs ALL day. I probably used it 6-7 hrs last Sat without problem.
Dont get all worried because I mentioned it is 3 times the size. Your looking at 4.25 OZ instead of the original being 1.5 OZ. I have 2 of these BP 827 and and a mid sized BP 819 at 1500 mAh only plan on using the mid size BP 819 and the original BP 808 as a last ditch back-ups. Oh, WAIT - i didnt mention the BEST part. This BP 827 not only lasts 3 or 4 times longer BUT is actually cheaper than the Canon OEM original. (sorry Canon)
