What does 9V battery mean?
The nine-volt battery, or 9-volt battery, is an electric battery that supplies a nominal voltage of 9 Volts, actually 7.2 to 9.6 volts, depending on technology. Batteries of various sizes and capacities are manufactured; a very common size is known as PP3, introduced for early transistor radios.

What is the full charge of a 9-volt battery?
According to the Energizer Battery Application Manual, a new 1.5V cell typically has an open circuit voltage of 1.58V. A nine volt battery has six cells, so a new would have an open circuit voltage of 9.48V. A reading of 9V indicates a battery with no to less than 10% discharge.
Are there different types of 9V batteries?
No, unfortunately there are very small differences in size of 9 volt batteries, even in brand name 9v batteries such as Energizer (or Energizer Industrial) and Duracell (or Duracell Procell). This plays a significant role in 9v batteries fitting properly into a device.
Why are 9 volt batteries different?
Other 9V Battery Facts Explained A 9V Battery is not exactly 9V in voltage. A nine-volt battery is standard battery size and shape, not the actual voltage or nominal voltage itself. Some of these batteries have working voltages ranging from 6.5V – 8.4V. Only 9V alkaline batteries have a voltage that is exactly 9 volts.
Are all 9 volt batteries the same?
How long will a 9-volt battery last?
Li-ion batteries have a nominal voltage of 3.6V and 3.7V. Rechargeable nine-volt batteries usually come in two options: these are NiMH and Lithium. Lithium batteries double the NiMH capacity. NiMH’s 9V battery capacity last for about four hours with the rechargeable Lithium lasts for 7 to 7.5 hours.
What 9-volt battery lasts the longest?
