A495 and batteries Recently bought the PowerShot A495 as a gift and am a little puzzled by the instruction manual regarding batteries. It says to only use AA alkalines or NiMH recharageables. But what about lithium AAs, like Energizer Ultimate Lithium? Is there any reason not use them? I find lithium AAs last MUCH longer than alkalkines in a different digital camera I own (and which, I now see, also doesn't mention standard lithium batteries in its instruction manual). (I use NiMH batteries as a fallback, but don't always have them at hand.)
There is no reason you cannot use lithium batteries. Disposable lithium batteries are relatively new on the market and not available everywhere so that may be why Canon neglected to mention lithium batteries specifically in the manual. Not to worry though, go right ahead and use them, you'd be crazy not to.
Crazy to not use lithium? Hardly. The main reason to not use lithium disposables is their substantially higher cost than alkalines. The reasons to choose them are lighter weight, longer shelf life and better low temperature performance.
