The invention belongs to the technical field of battery terminals, and discloses a method for improving the combinability of a cast copper terminal, which comprises the following steps of: firstly, staining the terminal with a soldering flux, then drying the terminal stained with the soldering flux, then carrying out tin staining on the dried terminal stained with the soldering flux, then carrying out heat preservation on the terminal stained with the tin, and finally, conducting casting. According to the method, the terminal stained with the soldering flux is dried and then stained with the tin, so that the problem that in the prior art, due to the fact that dry cloth is used for staining the terminal thoroughly before the terminal is stained with the tin, soldering is not firm after tin soldering and casting is carried out is effectively solved, heat preservation is carried out after tin staining, and the casting temperature is controlled; and the bonding property between casting lead and copper is guarante
