You can also use a bench power supply with CC CV if you're careful.
Set voltage to 3.8v and current to 0.5A, then attach it to the + - pads of the battery. That'll give you enough capacity to boot and charge normally.
Be sure to:
- Not leave unattended, it should be in visual range and close to you at all times.
- Feel the battery occasionally for heat, if it's noticeably warmer than ambient at a 0.5A charge the battery is dangerously damaged.
- Occasionally check the voltage, if it isn't rising either the contacts are bad or the battery is bad.
