I use three batteries in rotation, as I am frequently travelling in places where there is no electricity. When I traded in my old PowerShot S410 for a new PowerShot SD750 I took a chance on buying two generic batteries ($12 instead of $42).
Both generics were slightly less than perfect, in that they would regularly activate the ‘low battery’ icon/light even when they were fully charged. Occasionally, they would even evoke the ‘change battery’ message. On these occasions I had to open the battery compartment, partially remove the battery, then re-install it, in which case I could now proceed to take pictures with the same battery.
My sense was that the total battery life of the generics was not dramatically shorter than the Canon original, although I did not attempt to measure this precisely.
As soon as I was able (about a month after I bought them, as I was travelling at the time) I returned the generics to Amazon and paid full price for the Canon original. Although the generics could be ‘worked around’ it wasn’t worth it to me, as I discovered I was more interested in taking photos than in saving $30 (times 2).
This is the exact same battery that came with my Canon SD200 camera (digital elph). I wanted to have a spare, and while you can find the replacement batteries (generics) for about 1/2 the price I really didn’t want to risk anything going wrong by using any other type of battery. It takes a charge well and has a nice life to it, I am satisfied.
The value of having a second camera battery cannot be overestimated because the battery cannot be charged on the camera on most models. Swapping out batteries gives you continuous coverage and if you have a 2 Gig memory you can take a thousand pictures should you choose to do so. Moreover,the battery has a neat little cap with a built-in indicator which allows you to easily tell a depleted battery from a fully-charged one and eliminates the chance of spare change in your pocket or purse from shorting out the terminals. Strongly suggest you have one of these.
