In a battery race, the official Xbox Wireless Controller easily trumps most of its competition. Still, there's a good chance that your controller has run out of juice at the worst possible time, but fortunately, Target Circle Week is here and there are several deals on right now for spare batteries. These discounts will automatically be applied if you're logged into your Circle account, and membership is free for this program. There's also some hard-to-beat deals on Xbox wireless controllers at Target right now, so if you want to double up on hardware and batteries, this is a good time to do so.
First up, the most basic solution: fresh batteries. The Xbox controller can use both normal AA batteries or a rechargeable battery pack, and some Xbox players prefer to throw in a few Duracell or Energizer batteries when they're in a pinch. Target is offering a 24-pack of long-lasting Energizer batteries for $18, although you can get the same deal at Amazon for only $14.
The other option is to purchase a rechargeable battery pack, and there's a good mix of official and third-party accessories available. These are sold separately--Xbox wireless controllers do include a pair of AA batteries to help you get started--but they're more economical in the long run. The official Xbox play and charge kit is down from $25 to $20 this week, while the PowerA dual-charging station has been discounted to $24 this week.
