PURPOSE:To easily judge whether a battery is in a charged state or in a discharged state by mounting a manual indicator which selectively indicates one content from several contents on the outer wall of a battery case. CONSTITUTION:An indicator 3 which instantaneously judges whether a battery is in a charged state or not is mounted in a part of the outer wall of a battery case 2. A switching knob 4 of the indicator 3 has an indicating recess 5 on its surface and has an engaging projection 6 on its back. By engaging an engaging hole 7 installed on the outer wall of the battery case 1 to the engaging projection 6, the switching knob 4 is slidably mounted. In an information indicator 8, A shows a charged state and B shows a discharged state. When a battery is charged, the recess 5 of the switching knob 4 is set to the position A of the indicator 8, and when the battery is discharged, the switching knob 4 is slided to the position B. Even when many battery cases are carried, the case is easily judged whether the battery is in a charged state or not. |
