A battery connector includes a housing having a terminal recess and a plurality of electric terminals. The terminal recess has an inlay recess in the bottom of the terminal recess and a receiving cavity extending from the top of the terminal recess to the inlay recess, and an opening is dug at the end of the inlay recess. The electric terminal comprises a base portion, a contacting portion and a soldering portion. The base portion is received in the inlay recess. The contacting portion extends out of the receiving cavity for connecting the battery. The soldering portion was exposed by the opening of the housing. The repairman can replenish solder to the soldering portion by the opening of the housing if the machine omits soldering the soldering portion of the battery connector during excessive production.
