Popular Science: About 9V Battery Knowledge and Type

The 9v battery is known as the 'layered battery' and is named for its internal structure of six microchip battery stacks. Also known as PPP3 battery, the nominal voltage is 9V (the actual factory voltage is slightly higher, gradually decreasing with use), the size specification is 26.5mm in width, 17.5mm in thickness and 48.5mm in height. According to the different electrolyte materials, the main types are lithium battery (lithium8.4v), carbon 6F22 (carbon thick bowl), alkaline 6LR61 (Alkaline) disposable 9V battery and nickel-hydrogen (Ni-MH), nickel-cadmium. (Ni-Cd) combined secondary 9V battery. Mainly used in transistor radio (early products), walkie-talkies, remote control toys, smoke alarms, wireless microphones, multimeters and other electronic and instrumentation products. The main advantage of this battery is its ability to provide a high operating voltage for the device in a compact configuration.

9V battery type

The 9V carbon battery, also known as the 6F22 laminated battery, is a stack of six elliptical small-sized batteries that maximize battery space. Because it is an ordinary carbon battery, it is better to evaluate the discharge performance of this battery, which is better placed in the actual use environment to better explain the performance. Suitable for low current, intermittent working environment. This battery may leak after prolonged use. In the picture below, a picture is a discharge effect diagram of a 9V carbon battery tested under three different discharge conditions, which shows what work environment it is suitable for; the other picture is three different combinations, the left side It is a carbon 9V battery, 6 F22 models, with a 9V alkaline battery 6LR61 in the middle, 6 LR41 batteries stacked on the right, and a 9V battery consisting of 6 column alkaline AAAA batteries on the right. Different compositions and cells have important differences in their discharge and storage.

9V alkaline battery (6LR61)

9V alkaline battery, also known as 6LR61 battery. There are two forms of composition, as shown. Alkaline batteries are superior to carbon batteries in heavy-duty discharge conditions. The stacked battery structure storage time is about 1-3 years, and the column structure storage life is longer, about 3-5 years.

9V nickel-hydrogen secondary battery (23F6-220)

The 9V NiMH battery is divided into a 9V round battery and a 9V square battery. It has two forms, as shown in the figure. It can be recharged more than 500 times, which is longer than the carbon battery. It has a long life and is environmentally friendly. Widely used in toys, remote control cars, remote control aircraft.
