Depends on how the Battery Management System inside the battery was designed. Some shut everything down to prevent damage, and then can be reset to again allow charging. Contact the manufacturer for advice. If it was allowed to go totally dead, and kept in that condition for any length of time (hours/days), odds are very high it is permanently damaged. One might wake it up enough to accept a charge, but it likely will have no capacity. Also unknown as to the chemistry of the battery. Some "flavors" of lithium batteries are notorious for almost unstoppable fires if damaged and then forced to take a charge. Others (LiFePO4) will not have that issue, but just won't ever be as "good" as they were.

Be safe, and do your attempts at revival outside, away from anything you care about that might burn down....
