PURPOSE: To provide a battery terminal voltage indicator which is installed on a battery and is usable for indicating its charged state. CONSTITUTION: A battery voltage indicator includes a flexible substrate 21 having the same circumferential shape as the battery. On one side surface of the substrate 21, indication coatings 23, 25 are formed. When pressure is applied to a designated point on the surface of the substrate 21, the indication coatings 23, 25 are contacted thermally or electrically with a conductor circuit pattern 28 that can be temporarily connected across the terminals of the battery. The conductor circuit means allows the indication coatings 23, 25 to cause a visible change that shows the charged state or the voltage of the battery. |
