7D Batteries is there a cheaper version?

I got two Opteka ones for my 450D, they seem fine - try them?
 
7D batteries are chipped. I'm not aware of any that work with the Canon charger so ended up getting another Canon as a spare.
 
They give a indection via the lcd, but you can also get a battery level in a % terms via the menus. Find my battery last for around 1200 shots and being left on stand by for most of the day.
 
I have two in my gripped 7D... I just checked the battery meter and I've taken 836 shots and still have 45% charge remaining.

Hope that helps to give some idea.

Damn, thing must be bad!

You have spent £1200 at least on the body and you can't stretch to £55 for a spare battery? :eek:
 
The only aftermarket batteries I could find require a different charger, and the reviews aren't great.

It does annoy me that decent xxD compatible batteries can be picked up for under £10, but genuine ones are many times that in price.
 
My Opteka ones for the 450D both work in the Canon charger.
 
I purchased one of these for my 7D from Ebay. I got it as an emergency backup and have used it once or twice without problems. It does not show remaining charge on the LCD, but I am not going to spend £60 on an official battery that will sit unused 99% of the time. They probably cost Canon a fiver to make.

If you regularly shoot 100's of shots per day buy an official battery. If it is for emergency backup this works fine.

Soon 3rd party batteries may be a more viable option if this firmware does show battery level remaining using them in the 7D. We'll have to wait and see I suppose.

£1099 actually :)

Also i saved and sold a load of stuff to afford it, and still at school i earn £38 a week so thats nearly 2 weeks wages which at the moment i can't afford.
I will be able to afford it soon enough but i need it for next week which is why i was after a cheaper alternative.
 
I have a 3rd party grip (5D2) and run one canon battery and a 3rd party battery. This shows the battery power since the canon battery is there (have to put it in first). Gets round buying a stupidly overpriced canon battery
