Usage of 3rd party battery for ixus 430

[Catpuke]

I am thinking of getting a 3rd party battery so that my cam can remain operational when the original battery is being charged. I am wondering if I keep switching between original and 3rd party batt in the camera, will it have any adverse effect on the cam? Anyone doing the same thing have any comments on this?

This is becoz i notice the difference in the mAh rating between orignal and 3rd party battery. What is this mAh rating anyway?

And besides the price and mAh rating, what other differences are there between the 2 batteries?

Thanks

The camera wil be fine.

I'm using the origonal Canon plus a clone with my IXUS 400, no problems.

mAh (milli Amp hour) is the capacity of the battery when fully charged. For example if the battery is rated at 1000 mAh and the cam consumes 1 Amp then the battery will last for 1 hour.

Thanks for clearing that up. Hmmm.. I am wondering. Since 3rd party batteries last longer and are cheaper than original ones. Are there any reasons why people still use original batteries?
