I was wondering how long these batteries would last in the new camera I was going to buy. If it doesn't have at least a 2 hour life then I wont buy it.
That's not really a question anyone can answer. When anyone, a company or otherwise tries to give battery life, the answer is always estimate, usually over estimated, and reflects optimum usage patterns etc. If you can find them, look for Sanyo AA Eneloops, which are superior, and hold their charge for a -long- time, whereas NiMH batteries lose 80% of charge after a month roughly.
