| Zusammenfassung: | A battery pack (
10
) for a power tool (T) includes a casing (
11/12
) housing rechargeable cells (
24
). A receiving bay (
18
) in the casing (
11/12
) receives slide-in parts of the power tool (T), or of a recharging stand (
20
), to retain the battery pack (
10
). A pair of primary electrical contacts (
16
) is located in or adjacent the receiving bay (
18
). A recess (
15
) opens into the receiving bay (
18
). A supplementary electrical contact (
17
) is located within the recess (
15
), and a user-manipulable catch (
23
) is also located therein alongside the supplementary contact (
17
). That is, a single recess (
15
) houses both the supplementary contact (
17
) and the mechanical catch (
23
). The supplementary contact (
17
) is usable when recharging the battery (
24
) to relay battery temperature information to a recharging stand (
20
), but has no function when the battery pack (
10
) is attached to the power tool (T). The catch (
23
), useful in retaining the battery pack (
10
) to the power tool (T) has no function with the recharging stand (
20
). |
