A novel contact arrangement enables selective charging of battery packs or the transfer of information between a battery pack and an electronic device. According to one novel feature of the invention, a charging contact (408) is positioned in a region (410) outside of the area covered by the contacts of conventional cells. Therefore, a charging contact terminal of an electronic device will only apply charging current to rechargeable cells to avoid unintentional charging of any primary cells. According to alternate embodiments, battery contacts can be placed at different locations to selectively charge batteries depending upon the battery type. According to other embodiments, information or data transfer contacts (406) can be located at different locations to enable the transfer of information.

Par une disposition de contacts innovatrice, on est en mesure de procéder à un chargement sélectif de blocs-batteries ou au transfert d'informations entre un bloc-batterie et un dispositif électronique. Une caractéristique innovatrice de cette invention consiste à placer un contact de charge (408) dans un secteur (410) situé à l'extérieur de celui où apparaissent les contacts des éléments classiques. De cette manière, la borne du contact de charge d'un dispositif électronique ne peut appliquer son courant de charge qu'aux éléments rechargeables, ce qui évite de charger involontairement des éléments primaires. Dans le cas d'autres configurations de cette invention, les contacts de batterie peuvent, selon le type de batterie utilisé, se trouver à divers emplacements, pour charger sélectivement les batteries. D'autres modèles de la même invention sont munis en divers points de leur structure de contacts de transfert d'informations ou de données (406).
