Like many P&S cameras now, my new camera uses a small rechargeable lithium battery. I decided I needed a second battery that I can have charged and ready to go when the first one goes flat while I am out and about.
I was surprised at the HUGE variation in prices. A quick search turned up prices from $75 for an original Canon brand battery, to $13 for a no-name brand - and that's just within Australia. From Asia, the price gets even lower. What also seems wrong, is that noname batteries from local battery stores are around $40.
I decided to risk buying the cheapest from a Australian source. I thought it was worth $13 to try a noname brand first, before I lashed out $75 for the Canon one. It will be interesting to see if it performs satisfactorily or not.
