What Voltage Is A Aaa Battery Dead. What is 15 volt battery dead. Apparently you can revive dead Ni-Cad batteries by zapping them with high voltage.
A battery is considered dead when it is depleted to a defined portion of its capacity. For 12v Nicad or NiMH AA or AAA rechargeable batteries 10v under load is considered dead. If that device stops working at 10 V or 08 V then thats when the battery is dead.
But electrical engineer Lee Hite has an easier test.
That said a voltage around 08 V to 10 V is appropriate for most applications. For example an alkaline battery like a AA or AAA has a nominal voltage of about 15V while the voltage of a LiPo battery will usually be around 37VNominal Voltage. A regular AA battery is a an alkaline battery has a 15 nominal voltage charge but when it is fresh or brand new it will have165 volts. Your average rechargeable AA battery 12V.
