[quote name='crunchb3rry']I was referring to the battery packs, not AA batteries. I had to break down and get a rechargeable battery pack tonight for the Guitar Hero Les Paul. For some reason, I have yet to buy a rechargeable battery kit that doesn't crap out on me after a while. Hopefully this one will last, and I hope the batteries can take a lot of charges. Although, to the guitar's credit, you can play for quite some time before you need to replace them.[/QUOTE]
All rechargeable batteries will eventually wear out. Those battery packs are always a bad value. You should just get a AA battery charger instead. As a matter of fact, there is a superior type of rechargeable battery called Eneloop that holds a charge longer than other types. An Eneloop charger with 4 batteries is like $22 on Amazon, and 4 extra batteries are $10.
