促すのを目的とする。In a battery pack using a conventional nickel-metal hydride battery (hereinafter simply referred to as a battery pack), the discharge characteristics at low temperatures are not good and a large current cannot flow. ), There is a problem that it is impossible to know whether or not it can be used unless the user actually works. In view of the above, an object of the present invention is to provide a battery pack that can be used or not to be used without actually performing work, and to encourage an operator to warm the battery pack when it cannot be used. .

を、作業者に促すことができる。Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view of the battery pack, and FIG. 2 is a bottom view. 1 is a battery pack containing a nickel-metal hydride battery, and 2 is a battery case. The battery pack 1 is provided with a push button 3 for attaching and fixing to a power tool (not shown). A heat-sensitive label 4 whose color changes according to a predetermined temperature is attached to the lower surface of the battery pack 1.
The color of the heat-sensitive label 4 changes at a predetermined temperature (for example, 0 ° C. or lower). At low temperature (below 0 ° C)
When the work is performed, the color of the heat-sensitive label 4 indicates whether the heat-sensitive label 4 can be used or not. So, before the worker works, look at the color of the thermal label 4,
If the color can be used, the operation can be performed as it is. If the color cannot be used, the battery pack 1 is used after being warmed. Therefore, it is possible to urge the worker that the battery pack 1 cannot be used unless the battery pack 1 is warmed at a low temperature (0 ° C. or lower).

ではない。In the above-described embodiment, the heat-sensitive label 4 is attached to the lower surface of the battery pack 1. However, the present invention is not limited to the lower surface. May be a surface. Further, the thermal label has a form in which the color changes at a predetermined temperature, but may have a form in which not only the color but also a temperature display such as “−5, 0, +5” is changed, and the label can be used. May be displayed in the form of “○” and changed to “X” when it cannot be used. In other words, the present invention is not limited to the above embodiment as long as the display can be changed to determine whether the display can be used or not.
