I will not debate pricing. But want to note the iGO batteries are widely available. Here's a link.

Your laptop maker should offer replacement batteries.

My laptop has a very bad battery life which is way too short and I am considering to invest in a high capacity lithium ion external laptop battery for it. I am thinking about buying a battery from this company called batterygeek. I just filled out one of their free battery audit forms on their website at www.batterygeek.net and am still waiting for their reply. Have any of you heard of this company? They seem to have a pretty good product at a reasonable price with a solid warranty but i'm just hoping on getting a second opinion from someone.
Thanks,
Jenn
