Is your PSP battery pack draining your resources? Then you can thank Sebastian S. Kresge for this. Sebastian who? Kresge put up a five-and-ten-cent store back in 1899. A million years later that store became K-Mart, which currently sells original PSP battery packs for $4 each. But wait, there's more. If you're also in the market for a PSP Car Adapter, K-Mart has that, too, for $3. Like we said, thank Sebastian Kresge for that!

Sony issued a warning to all PSP owners not to use third party battery to power up their PSP. The company urged the use of genuine Sony battery pack to protect against "the danger of ignition and explosion etc."  Sony said while they can guarantee the standards of their battery pack, other brands could cause "accident and breakdown and it is dangerous".

They also said to be on the look out for fake Sony battery packs since any damage caused the company cannot be held responsible for any damages cause by these knock-offs and third party battery packs. If you have experienced any kind of damage from using party battery packs other than Sony's, you may tell Sony about it. We don't think they will replace your PSP, but at least they can tell other PSP users "we told you so."
