J'ai remplacé la batterie de mon casque Marshall Major 4 avec car la durée de la batterie commençait à s'affaiblir, pour l'installer il suffisait juste de couper un petit bout du fil de l'ancienne batterie avec le connecteur et de souder les fils de la nouvelle batterie à ce dernier, puis de relipser le connecteur à la carte du casque.
