If you've ever had a controller die on you in the middle of a marathon gaming session, you might want to head on over to Tiger Direct where they have the Microsoft Xbox 360 Quick Charge Kit on sale for $17.99. Normally $39.99, this is a great price for an extra battery and the peace of mind knowing you're just a quick battery swap away from continuing your gaming domination. Average recharge for one battery is 2 hours, and 4 hours for two batteries.
We're not sure how long the deal is on for but, if you're interested, we'd advise you hop on this before quantities run out.
The deal is available online and in-store.
