I notice the in the manual for the Canon 60D that you can "register" your\nbattery packs (pp269).\n(The manual can be found at\n[URL]http://gdlp01.c-wss.com/gds/9/0300004019/01/eos60d-im-en.pdf[/URL].)\nYou can register up to six battery packs to the camera.\nBeing of a somewhat suspicious nature it occurred to me that this may be\nCanon's way of making sure you only use their batteries instead of cheaper\ngenerics. (remember inkjet cartridges with chips.)\n\nHas anyone had any experience with this, i.e. successfully used generic\nbatteries in a Canon 60D camera?
