This is a replacement for the battery in an 30 year old screwdriver sold under two names, AEG and Milwaukee. New life for this tool. Reasonable price too.Battery charger overheated had to stop charging. Had to use a home made charger.What I wantedAfter a few charges, the battery died! It doesn't charge anymoreWorks great in my old screwdrivers.Battery was defective as it over-heated in the charger and was too hot to touch. Battery casing warped. May have just been this one battery but I won't buy another.When charging, it got so hot the red plastic housing of my Milwaukee charger got soft and you could hardly touch it....JUNK !!!horrible they don't hold the chargeC'est le même numéro de produit que les batteries original, il y a une petite différence sur la forme extérieur de la batterie mais rentre dans le chargeur original. Elle se charge mais le chargeur ne reconnais pas son niveau de charge et n'arrête pas de charger. La batterie devient brûlante. Pourtant le chargeur fonctionne bien avec les vieilles batteries originalPièce de remplacement adéquat
