The 3 Red LED Blinks indicate the battery is dead
If you want to recover it use the original charger that came packed in the box and put it on charge for a couple of hours it'll take around 2-3 hours for it to start charging again (I've experienced this issue) If the problem still persists try a new battery
However i the first method works you may encounter another problem, and the device may be bricked (This happened to me after i recovered my battery) What you will need to do is use flashtool and flash Stock Rom again, But if the device boots up normally without hitting into a bootloop i guess it's working normally
(This problem happened to my Xperia J)
Note: If you're planning to buy a new battery make sure you buy a genuine one, as most people try to re-create the original battery and it just shows the wrong battery percent I've also experienced that and i blew £10
