Abstract

La présente invention concerne une structure de bloc-batterie permettant une utilisation sur le long terme d'une batterie plate dans divers types de dispositifs électroniques. Une première batterie plate (1) et une seconde batterie plate (2) sont connectées électriquement en parallèle dans la structure de bloc-batterie. Un porte-batterie (3) comporte un crochet (33) qui accroche une première surface (14a) de la première batterie plate (1), lorsqu'elle est logée dans le porte-batterie (3), afin de retenir de ce fait la première batterie plate (1). Une seconde batterie plate (2) est agencée au-dessus de la première surface (14a) de la première batterie plate (1) logée dans le porte-batterie (3) via un élément intervenant (4) avec une seconde surface (24a) de la seconde batterie plate (2) faisant face à la première surface (14a) de la première batterie plate (1). Une première distance (L1) entre la première surface (14a) de la première batterie plate (1) et la seconde surface (24a) de la seconde batterie plate (2) est supérieure ou égale à une seconde distance (L2) entre la première surface (14a) de la première batterie plate (1) et la même hauteur que le dessus du crochet (33).
