1. An electrical combination comprising:
- a power tool having a first connecting structure, the power tool including a tool housing and an electric motor supported by the tool housing and operable to drive a tool element, the first connecting structure having tool leads;
a battery having a second connecting structure, the first connecting structure being incompatible with the second connecting structure, said battery having first battery terminals;
a battery charger having the first connecting structure, the battery charger having charger terminals; and
,an adapter separate from and connectable between the battery and the tool housing to support the battery on the tool housing, the adapter having adapter leads for electrically coupling the battery to the power tool, the adapter having a mechanical lockout for allowing an electrical coupling between the adapter and the power tool and preventing an electrical coupling between the adapter and the battery charger, wherein the mechanical lockout comprises a barrier disposed between the adapter leads and having a width that is comparatively greater than the width of a receiving recess disposed in the battery charger to prevent connection of the adapter with the charger.

4. An electrical combination comprising:
-
a power tool having a first connecting structure, the power tool including a tool housing and an electric motor supported by the tool housing and operable to drive a tool element, the first connecting structure having tool terminals of a first configuration; a battery having a second connecting structure, the first connecting structure being incompatible with the second connecting structure, said first battery having first battery terminals; a battery charger having the first connecting structure, the battery charger having charger terminals of a second configuration that is comparatively different than the first configuration of the tool terminals; an adapter separate from and connectable between the battery and the tool housing to support the battery on the tool housing;
the adapter having adapter leads of a third configuration that allows electrically coupling of the adapter to the power tool and prevents electrically coupling of the adapter with the battery charger, wherein the tool terminals have a first length that is adapted to electrically couple the adapter to the power tool and that is comparatively longer that a second length of the charger terminals that is insufficient to electrically couple the adapter to the battery charger.
