Hello,
I have seen batteries as high as 5400mah on ebay and was wondering if someone knew what was the largest capacity battery i can use for my optura 50. On the canon site it shows their largest as a 1450 mah. I emailed a person selling a 5400mah on ebay and she said it would work with my cam but i just wanted to know if anyone had used one before.
thanks, mike

There is no limit on the capacity you can use, it just depends on how big a battery you can physically handle. Make sure to read this thread (http://www.dvinfo.net/conf/showthread.php?t=49445) regarding 3rd party batteries and the warranty on your camcorder.

Thanks Michael for the link,which does make me think twice about 3rd party batteries. Maybe sticking to the 1450mah canon battery would be a smarter choice . If anyone else has used these larger batteries i would appreciate the feedback, good or bad. Thanks, Mike

Use of 3rd party batteries is very common. Didn't want to scare you off completely, just make sure to use known brands. Search this site for Lenmar, Power 2000, and CTA batteries for user feedback.
