Canon 5D Replacement BP511 Batteries - where?

[futureal33]

Hi all,

Just picked up a Canon 5D and it only has 2 batteries, as I plan on using this for weddings I would ideally like to at least double that number.

I also have a 5D2 which runs on replacement batteries purchased off eBay and have had mixed results, some better than OEM others died after one cycle.

Just wondering if anyone could recommend me a non-OEM replacement battery BP511 for the 5D which is cheap and good?

Thank you

How does a pair of batts for £11 delivered sound? BP511 is simple tech - no chips - so not much to go wrong.

So long as you're not in an urgent hurry. I bought a couple many years ago, for my 30D and 40D, and they were just fine. I assume they're just as good today as they were back in 2006.

Tim,

Would you think they'd be better than these

One side question, do the batteries you mentioned hold the date information? I had a camera a while back which each time you took the battery out it asked for the time&date when you put it back in! They were cheap replacement batteries...

Thanks

I honestly have no idea. The eBay ones claim a high capacity, but I'd take that claim with a large dose of salt. It's been a couple years since I last used BP511 batteries. I know the 7dayshop BP511 batteries are well recommended all over the place, and so cheap it would be rude not to try them. Maybe the eBay ones are even better. I have no way of knowing. This is not complex technology. I'm sure either choice will be fine, given the meagre price either way.

As for retaining date/time, that is not the job of these batteries. Your camera will have a little button/coin cell in it that takes care of that side of things, probably slotted into the main battery compartment. Possibly that could be getting on a bit now and might need replacing.

Tim,

Ah that makes sense - thanks for clarifying.
Just ordered 4 of the 7dayshop ones, the reviews on the website are really helpful!

Thanks for the help mate

I just looked at the reviews. Mine is listed at #06. Note the most recent review was back in 2008.

They should be fine for your 5D. I've been using 7dayshop for over 10 years and have some 8 or 9 year old rechargeable AA batts that are still going strong.
