I don't see anywhere in the rules where it states you can use an alternative 7.2 volt backup battery. As I interpret the rules this year, you must use the one supplied.
EDIT: My interpretation is indeed wrong, <R68> is clear that any 7.2 volt battery can be used. Sorry for the bad info (and thanks, Alan A.)

I agree, but teams designing such a charging circuit MUST consider the safety aspects of such a device, specifically that it really must be a charger and not just a voltage source. A simple voltage source runs the risk of overcharging the battery.
A good choice for such a charger circuit would be the
MAX 713 which is available from almost everyone, and also comes in a 16-pin DIP package (so you don't have to mess with surface mount stuff).
