Fits Senco FN65DA Fusion finish nailer. On board fuel gauge shows charge levels and gives warning before battery fully discharges. Battery can be recharged when hot. Does not suffer from memory loss and holds full charge when not in use.
I have had this battery for about a year and it will now not take a charge. I have used it very little during this time period. I love the nailer, but the battery sucks and is way to expensive to replace.
