I was looking at these batteries and it seems that couple things are erroneous in the comments above. The macs can use whatever power is available at the voltage of the unit. They are not looking for a switching power supply adapter. Therefore I don't see the point being made by HyperMac. The MacBook air actually uses a different connector though it is still magnetic. Thus the voltage difference is not a solid point. Now if you have adapters that plug into a standard cabling piece to allow for the different mag-safe connectors and want the different voltages then that is fine and a slide switch to go between the two voltages would not be an issue IMHO. Supplying as much VA of power behind the voltage is the key so the battery would hold the cpu up the longest time. As for ownership of HyperMac by battery mfg. I'm dubious. 95% of these are made in China and since I deal with china companies all the time this seems unlikely. Now there could be purchasing agreements with HyperMac and that does happen all the time but as we see in the news everyday China does not really adhere to agreements, patents or copyright laws for the most part and just want the orders and money to flow to them. Additionally if you go to China you see that there are literally 100s of mfg.s of LI battery packs and they all tend to follow similar design packaging that is why they look similar.
"I'm a college student looking for a new laptop, but almost all of my media I receive digitally. I'm looking for a laptop, not a netbook, without an optical drive, and budget sensitive. The optical drive will just be a waste of space, when I can have thinner laptop. What's out there?"
