The batteries seem to work well to me. The only thing is, with these batteries, the base never indicates that the earphone is charging. The light always remains green. However, the old battery had the red light, before finally turning green. Despite this inconvenience, I am satisfied.

Les batteries me semblent bien fonctionner. La seule chose est, qu'avec ces batteries, la base n'indique jamais que l'écouteur est en train de se recharger. Le témoin reste toujours vert. Pourtant l'ancienne batterie avait le témoin rouge, avant de finalement passer au vert. Malgré ce désagrément, je suis satisfait.
