Has anyone here changed the silveroxide battery so far? My friends tell me that it does not need a change at all unless one is particular about the programs that are stored.

Not sure if I need to tamper with it prior to the AP calc exam.

Also, any idea about the approximate number of hours of usage for the AAA batteries? Not planning to change either the AAA or the silveroxide batteries prior to the exam as the plan is to take a few spare AAA batteries just in case.

thanks
