That would indicate that the battery is most likely at fault. I would get it replaced and see how that goes. Fortunately batteries are relatively cheap to get replaced. IMO I recommend a local reputable repair store to get the battery replaced. Should be a straight forward repair for them as it shouldn’t immediately turn off when the battery is replaced.
