Hi there I'm new to the AV Forums and suprise, suprise - I have a quesiton! I have just purchased a Optio 330 GS, which I'm very happy with! However, I'm trying determine the best method regarding batteries. As it is very new it currently running off the lithium battery that was supplied with the camera, which I understand is not rechargeable. I would ideally like to purchase a rechargeable lithium battery but couldn't see this as an accessory for the camera. I thought lithium might be better than normal AA as I tried them and they lasted less than half an hour! Basically although I can see it as an official accessory is there a lithium battery (maybe the same one at the 300RS? ) that I could use. I'm basically looking for the best option in terms of battery life I guess. Cheers!
