The invention discloses a method for verifying the storage reliability of a lithium thionyl chloride battery. The method comprises determining the required number of samples and the shortest equivalent storage test time by means of an index requirement; estimating the expected equivalent storage test time of an test sample, and determining a test scheme according to different cases; performing a test according to the scheme, calculating the failure number of samples, fusing different test item data to obtain total equivalent storage test time and a failure rate confidence upper limit, calculating the actual storage life and the storage reliability of the battery, then obtaining a battery storage reliability conclusion, estimating the battery storage capacity and the use safety through the laboratory test data when the total equivalent storage test time is insufficient, and comprehensively authenticating the battery storage reliability in combination with the engineering analysis and evaluation. The method coo
