1. A battery module comprising:
a plurality of rechargeable batteries each of the rechargeable batteries comprising:
an electrode assembly;
a case and a cap plate accommodating the electrode assembly;
a first terminal post electrically coupled to an electrode of the electrode assembly and consisting of a first metal composition;
a first terminal plate comprising a first plate coupled to the first terminal post and consisting of the first metal composition
and a second plate and a third plate both coupled to the first plate, spaced from the first terminal post, and consisting
of a second metal composition different from the first metal composition, wherein the first terminal post extends within an
opening in the first plate in a direction away from the case;

a second terminal post electrically connected to another electrode of the electrode assembly and protruding from the case,
and a second terminal plate welded to the second terminal post, wherein the second terminal post, the second terminal plate
and the second plate comprise the same material; and

an insulating gasket between the cap plate and the first terminal plate, wherein the insulating gasket directly contacts the
first plate and the second plate; and

a connection member electrically coupling adjacent ones of the rechargeable batteries together, wherein the connection member
is welded to the second plate and the third plate of a first one of the batteries and to the second terminal plate of a second
one of the batteries and wherein the connection member consists of the second metal composition.
