ABSTRACT:
A power pack (1) for use as an alternative to non-rechargeable batteries (3) in a toy (2) comprises a plurality of series connected rechargeable cells (13) accommodated within a casing (7) which is sealed permanently against removal of the cells and carries output terminals (11A-11C) arranged to cooperate with the power input terminals (6A-6D) of the toy when the power pack is inserted in place of the cells and with the contact terminals (25) of a recharging device (18) when the power pack is engaged with this device for recharging the cells. The power pack casing is shaped to cooperate with the toy (2) and recharging device so that it will engage with each in only one predetermined position.
