Chief, maybe your prob arose when u mixed the original and the 3rd-party.. I'm not too sure but could be a possibility..
If I'm rich, everything I get original...
I just got a 40D recently, and is looking for good 3rd party batteries too.
Anyone knows which brand is better? :dunno:
DiviPower - sold by MS color
EastGear - by East Gear
What is CP's batteries - is CP the brand?
Is Photix sold in Singapore?
