Abstract
A battery substitute pack (10), comprising a casing (15) dimensioned for accommodation in a battery compartment of predetermined size and housing therein an energy transfer circuit (14, 30) for receiving electrical energy remotely via a contactless charging unit (20-), and a positive supply terminal (16) and a negative supply terminal (17) coupled to the energy transfer circuit (14, 30) for connecting to corresponding positive and negative contacts of the battery compartment. Preferably, the battery substitute pack (10) contains at least one rechargeable cell (11) which may be recharged via induction by means of a contactless charging unit (20).
