Canon 40D Battery

Atina Tan , Dec 24, 2007; 01:19 a.m.

I just recently, 2 days ago, got a Canon 40D with 2 4 hr batteries. However, after charging both batteries until the light on the charger stopped flashing, plus some, both batteries died after at most 10 min. Did I just have the bad luck of getting 2 bum batteries or is this a common problem?

It's not a common problem.

If you put the batteries back in the charger, what % charge does it think that they have?

100%

"2 4 hr batteries" - they don't really come with those specs and for two to fail would be unusual. Are they Canon BP-511A 7.4V 1390mAh (Li-ion) batteries as recommended for your camera? Are they being charged in the Canon CG-580 charger? When you put them back into the charger it indicates they are fully charged - why do you think they have both died?

Yup both batteries are the exact battery you described and so is the charger. When I first got my camera and thus the batteries, I put them in the charger and they blinked once. After a few hours the light was solid. Now when I put them into the charger the light is still solid, but when I put them into the camera, the camera's battery (or low battery) flashes and it won't let me do anything. I think I just got unlucky enough to get 2 bad batteries.

Could be - go to Sterlingtek.com and buy some spares for a great price.

Maybe. Also try cleaning the contacts with alcohol.

*contacts both in camera and battery.

I'd be a bit suspicious of the camera - it sounds like the batteries went through a normal charge cycle - and are still indicating full charge.

Either way it's a problem - Can you return the whole kit for your dealer to sort out?

Atina Tan , Dec 24, 2007; 05:42 p.m.

Thanks for all the advice. I'll try cleaning the contact points on both batteries and camera with alcohol. I called the dealer where I ordered the camera and they are sending 2 new batteries w/o any cost or fuss.
