9V battery voltage curve

Summary of tests, see discharge curves below. The nine-volt battery, or 9-volt battery , in its most common form was introduced for the early transistor radios. This type is commonly used in walkie-talkies, clocks and smoke detectors.

Alkaline-Manganese Dioxide Battery. Delivered capacity is dependent on the applied loa operating temperature and cut-off voltage.

Please refer to the charts and.

V, depending on the model in question.

In the rest of this discussion, 9V refers to the 9V size, not the actual voltage. The battery capacity will be better with lower drain currents. To determine the battery life, divide the capacity by the actual load current to get the hours of life. Impedance: Typical Weight: gm ( oz.) Typical Volume: 22. Note that they define the end voltage and this means end of test because to drag more enrgy from the battery is going to either . When fully charged you will see nearly 4. V on the cell but it will quickly drop to 3. Note 1: See the discharge curves , the maximum continous current depends on the voltage sag you equipment can accept.

D cells are typically used in high current drain applications, such as in large flashlights, radio receivers and transmitters, boomboxes, products with electric motors, safety systems, Geiger counters, . Another type of alkaline batteries are secondary rechargeable alkaline battery , which allows reuse of specially designed cells. Compared with zinc-carbon batteries of the Leclanché . Whether alkalines or rechargeable, voltage is voltage , and your device neither knows nor cares who made the batteries. Your device is certainly not going to tattle on you to the . Low impedance, better performance at low temperatures.

Up to year operational life in most ionization-type . Since the initial launch, there have been over 1million . Operating Temp: -40°C to 60°C (-40°F to 140°F). Storage Temp: -40°C to 60°C (-40°F to 140°F). Safety Features: Positive Temperature . The flat cell contains no voids or . Marketing Specification, Batteries.

Expected service life and representative discharge curves are shown on the following page . A battery can be made up of one or more cells. Car batteries contain six cells at 2. This Storm battery pack for quadcopters shows the discharge curve for their LiPo cells starting at around 4.
