This battery comes with no instructions but there are good videos on YouTube. But make sure you are looking at precisely your model as there are fitting differences.But it's given new life to my tablet.

Easier to install than I expected.

The charge in this battery lasts no time at all. 100% charge may last about 2 hours. Where as the old battery I replaced lasted at least 5 hours which was not good either. Hence the need for a new battery.
