I have struggled with 2 crappy play and charge kits for my XBox for the past year, neither of the batteries are brilliant. I finally invested in a set of Sanyo Eneloops and I have to say that I wish that I had done sooner. A set of 4 batteries and charger were cheaper than a play and charge and they last longer and I always have a set ready to go. If you want rapid charging you can always invest in the MQR06 charger which will rapid charge 4 batteries in under 4 hours but costs about a tenner more.
