You generally want the highest milliamp-hours rating, but of course the cost is the trade-off. Just curious, why so many batteries? I usually keep a charged spare set on hand, and I am thinking of getting a solar charger to take with me (maybe mount the panel outside a backpack). There is a good description of the battery ratings at web page (warning: pop-up ads on that site) Craig Miller Chandler, AZ
