Canon NB-2LH Rechargeable Battery Pack for Digital Rebel XT/XTi, PowerShot S30/40/45/50/60/70/80, G7 & G9 Digital Cameras

I have been using my Canon PowerShot S30 camera for a couple of years now. When I purchased it, I also purchased an extra generic rechargeable battery pack to go with it. At the time I figured I would save the money and name brands are not always better. Looking back on it, I wish I sould have spent the extra $25 and gotten a Canon battery. The generic battery only lasts about a 1/4 of the time that my Canon battery does. Also after a couple of years of use my Canon is still running strong while my generic battery barely lasts at all. I am now getting ready to purchase a second battery for my Canon for a family trip in September and I will only be purchasing a Canon brand battery.
THE BOTTOM LINE: If you are going to be cheap and a penny pincher, then you are going to get a cheap worthless battery. If you want a battery that will keep its charge and that you can count on, buy a Canon battery.
