Abstract: An organic electrolyte battery has a positive temperature coefficient resistor made of a resin to control and prevent overcurrent placed in electrical contact with both a sealing member of the battery can and a battery lid in a position where it is not subjected to crimping forces when the battery can is crimped onto the sealing member to close the battery can. In one embodiment, the resistor is carried on an annular member so that it is spaced inward from a crimping zone. In a second embodiment, it is disposed in the center of the lid and connected to the sealing member by a support member.
