All batteries exhibit a phenomenon known as self-discharge, i.e. when left unused for long periods they will slowly discharge due to internal leakage currents. Usually this gets worse when the battery gets older.

A Li-Ion cell is considered to be fully discharged when the cell voltage has dropped to 3 Volts. But self-discharge might drop the voltage still further. However, most charging circuits, including those built into Li-Ion powered gadgets, will refuse to charge a battery that has dropped below 3 V, it will consider the battery as being defective.

If the cell has not dropped too far below 3 V, one might attempt to force charge the cell by connecting it to a suitable power supply and carefully monitoring cell voltage and current. Once the cell has recovered to a voltage over 3 V, the charger will usually accept it and charge as usual. However, keep in mind that Li-Ion cells are somewhat fickle and charging a defective cell may result in Bad Things Happening. So if you want to be on the safe side, it would be better to just replace the battery.

A battery sitting in a discharged state for a long time is probably the worst thing for the health of the battery. Replacing the battery should probably get you going again if you didn't have any other issues.

You should be able to find a new battery for it if need be. Have a look on eBay or Aliexpress.

Try leaving it on charge (off a wall socket) overnight first though.
