All my Xbox360 controllers still work fine, but none of my PS3’ Dualshock 3s
Batteries for PS3 Dualshock are still available on ebay in my country. You just unplug a cable and remove a couple of screws. AA are not worth it.
AA should only used for flashlights (emergency), kids toys (safety) or when you are far away from an electricity network for much time (days, weeks).
