Claim:
1. A method for manufacturing a sealed battery, the method comprising: storing an electrolytic solution in a storage device in a sealed state; feeding a pressurized feeding gas into the storage device where the electrolytic solution is stored; after the electrolytic solution is stored in the storage device and the storage device is pressurized by feeding the pressurized feeding gas from a feeding gas feed source, injecting the electrolytic solution into a battery container via a liquid injection nozzle, the electrolytic solution being pressure fed from the storage device to the injection nozzle using the pressurized feeding gas; introducing a detection gas into the battery container, the detection gas being identical to the pressurized feeding gas; and detecting a leakage of the detection gas introduced into the battery container.
