batterys, canon 300d short life :(

[garethmob]

On original canon batteries my 7D did over 4.5k shots in one day on 1 1/2 batteries...

I have had some really ropey cheapies off ebay which had no where near the capacity and were filled with scrap cardboard.. I only wanted then for the cases...

I also had a cheap camera psu that blew up... fortunately the canera was ok..

Peter...

was that AP peter or just normal photography?

There are other advantages in using the dummy battery power supply as it's easier to keep the camera cool to reduce noise without affecting the power.

Normal.. I get a couple of hours of open shutter out of them...

The latter cameras and batteries are better than the earlier ones..

With the 1000D the batteries would charge in an hour and run for two so only needed two batteries all night...

I used to need three with the 350D

Good point that I've had my 1100D in a cooling box all day running tests (long exposure darks) so we'll see how long the battery lasts.

Battery lasted between 3 and 4 hours. That's on a spare battery I bought from Amazon. 7.4v 1200mAh. :- http://www.amazon.co.uk/gp/product/B0055WZPNK/ref=oh_o04_s00_i00_details

I expect to be cutting it open to use as a dummy to connect 8v power from an external supply. I now have 2 genuine Canon batteries as well.
