Review by Eric

the helmet has regained a second youth ... to see over time. greater capacity than the original Sony battery therefore logically more autonomy. For the moment I strongly recommend this replacement battery.

le casque a retrouvé une 2eme jeunesse… à voir dans la durée.
capacité plus importante que la batterie Sony d'origine donc logiquement plus d'autonomie.
Pour le moment je conseille fortement cette batterie de remplacement.
