All, This isn't a professional inquiry, but just curiosity. I have a rechargeable electric razor whose battery over a year ago failed to hold a charge. I have continued to use it as an ordinary mains-powered electric appliance, and I leave it plugged in all the time. Lately it has begun to feel warmer than it used to. Today the case was hot to the touch, and I disconnected it. What is happening to the battery? Note it is getting hot when the unit is turned off - no load on the battery internal resistance. It has to do with the charging function, but the battery doesn't hold a charge. The only reason I can use the unit at all is the power supply (built into the case) has enough ampacity to run the razor even with a dead battery. I don't recall the type of battery, NiCd or lithium. Does it make a difference?
