Without having to order online? I doubt anyone here could help you unless they are locally to you, because you'd need to call around to local stores. The odds of you finding such a thing these days is pretty slim to none, but you could still try. Also, in regards to laptop batteries and powerpacks, I would NOT recommend buying off-brand non-OEM junk, I'd only go with original manufacturer stuff. Thus, it would seem you're probably stuck with buying something from Gateway directly. You could always see if you have a local Craigslist, or even eBay, but that's your call. Good luck either way.
