Hi. I was wondering which batteries are best while traveling. I've read that alkalines are supposed to last much longer than those cheap heavy duty ones. I don't know all that much about these kind of things but I don't want the batteries to die while in the middle of a gaming session in the back of a car in the middle of nowhere. You get what you pay for when it comes to these kind of things don't you? I've used those cheap heavy duty ones in the past and they don't seem to last long at all.
