Hi all. I have a 5d replacement battery bp 511. According to the charger it is fully charged. Placed on a voltage meter it registers 7.4v which is label correct. However....when I place it in the camera it shows 1 bar then after a short while of being in the camera but turned off, it's apparently dead. Place itno the charger again. Within 2 to 3 minutes max its fully charged? ? Could the camera be faulty? Or the battery/ charger.

I would guess it's the battery. Is it a genuine Canon one? I had a cheapo one from 7dayshop and the same thing happened.

It's highly unlikely that the camera will drain the battery when it's off. This sounds a bit like a memory effect - not supposed to happen with modern batteries I know, but your experience seems to suggest it. I'd start again but buy a Canon battery. I have used both Canon and independents, and the Canon batteries outlast the others. I know they're expensive, but the cost of modern photography is relatively low. What you'd pay for a new battery is only about the equivalent to buying a processing a few films.

I,ve experienced this before when I bought a very cheap "too good to be true" battery it took about 30 charges then started to get less shots per charge. Now I have a couple of Duracell ones which are still going strong after 2 years regular use.

I have a similar problem with a Maxsimafoto battery (for a Pentax). After six months (about 20 cycles) it apparently charges in a few minutes but dies after a couple of exposures. I had a Hahnel that lasted a couple of years before doing the same thing. The original Pentax battery is much better, despite being 4 or 5 years old and used as my usual battery. I'd love to know who makes the batteries for Pentax and the other camera manufacturers ...

And yet I got a 5D battery from them & have never had a problem with it. I have heard that some Amazon supplied batteries have this problem

2 are from amazon yes. 1 faulted so they sent me a replacement. That also fails. Same sort of thing. No charge holding. Both under a year old.
Ah well. I'll see about a new battery then. Thanks for the input people.

I must have approximately 30 cheap, third party batteries, about 6 of them for a Panasonic camera, the rest for Canon DSLR's and I've never really noticed any problems or any loss of performance compared to originals. In fact, there was one occasion, where I had an issue with a 7day shop battery. I can't recall exactly what the issue was, it may be similar to the problem mentioned above. 7dayshop.com changed it for another one without issue. I guess like most things these days, you can get unlucky occasionally with a dud battery now and then.
Not a solution to the problem but in case it's of any use. When the charger indicates a fully charged battery, it isn't 100% fully charged and is best left for a good hour longer. This used to apply to batteries for the Canon 20D era of camera's, I presume it could still be rellevent.
Never let them get too hot, i.e. left exposed in a hot car and never store them when completely depleted.

Regarding your question about batteries draining when the camera has been switched off. I've found they certainly do self discharge but over quite a long period.
A very rough estimate would be perhaps 15% percent discharge over a few months.

Somewhat agree with that...certainly not the drastic conditions you're experiencing...I'd agree with...biting the bullet....and getting on OEM battery to compare...
