How to revive Li Ion battery which was not used for like a year?

[paparazzo79]

Hi guys.
I have this old netbook Asus Transformer T100 which I was not using for probably more then a year.
It really had great battery back last time it was used (lasted like
cca 10 h of its complete usage)
Tonight I wanted to turn it on but could not, battery was at 0% and to 100% charged pretty quickly and lasted only 15 minutes until complete discharge (back then I know it lasted like 10 hours).
Please tell me there is hope.
Now I am trying to discharge it again and charge just to try revive some cells in it if they are not complely dead.
Now I know this is old laptop but I have like same old tablets which I do care about and last me few hours of battery screen on time.
Is there a hope for this sweet boy?

Okay so far I did drain and charge battery in 3 cycles, so far showing battery health of a 32 % and was 2 %.
I will do few more charge7/discharge cycles, wish me luck...
