 I don't want a knock-off, too many problems, but they are out of stock on the Canon site. All the ones I find are not Canon products. Thanks.

Any "authorized" Canon dealers should be able to get you the real thing.

You can get a copy of the current dealer list here: http://www.usa.canon.com/app/pdf/dealer/CanonAuthorizedDealers.pdf

Online, B&H Photo (bhphotovideo.com), Adorama (Adorama.com), and Amazon.com will all have them in stock.

Dealers will sell 3rd party batteries as well as the genuine Canon battery so check the details to verify that you are buying a geniuine battery (these are all reputable sources -- they wont advertise a genuine battery and send you a knock-off.)

Also... batteries do not like to sit unused for extended periods. I own multiple batteries but they are all labeled so I can make sure I'm rotating them. This avoids constantly using the same ones over and over and ignoring others.

Thanks. Got one, it is a Canon and works great.
