One comment
It should be mentioned that "newer" models of this particular Chromebook are/have been released. The Chromebooks' battery compartment's design have been slightly modified in that the battery compartment are now reversed.
So, since the battery's connector cable is so short, it's impossible to twist it to fit.
So, make sure you're getting the correct battery for the correct "model".
FYI, the "older" models have the power button close to the back corner of the device, and the "newer" models have the power button near the middle of the device.
