The significance of lithium battery life improvement

The second part is the shape letter code, "R" stands for the cylinder, "S" stands for the square, "F" stands for the square (chewing gum) shape; the third part represents the battery size; the fourth part is the battery operating characteristic code, "M" stands for medium rate discharge, "H" stands for high rate discharge, and "S" stands for high temperature (100-150 degrees Celsius). For example: ER14500MS, which means that it can accept medium-rate discharge under high temperature conditions, with a diameter of 14.0mm and a height of 50mm lithium-thionyl chloride cylinder battery.

Lithium battery inside the battery that everyone can contact, and can really use the battery, I think it is lithium-manganese dioxide battery, lithium-thionyl chloride battery, lithium-sulfur dioxide battery three. I have a little experience and experience with these three batteries.

Lithium-manganese dioxide batteries are common and used in many places. They are also very convenient to buy, but the quality of each brand is different.

In addition to the button-type lithium-manganese dioxide batteries previously introduced, the most common lithium-manganese dioxide batteries are those used in conventional cameras for filming.

CR2, CR123A, CRP2, 2CR5. These four models of lithium-manganese dioxide batteries are very common. The jargon we sell at the time called them "three volts short (CR2), three volts long (CR123A), six volts short (CRP2), six volts long (2CR5)". CR2, CR123A are a single lithium-manganese dioxide battery, CR2 can also be called CR15266, its diameter is 15.6mm, the height is 27.0mm, the nominal voltage is 3.0V; CR123A can also be called CR17335, its diameter is 17.0 Mm, height is 34.5mm, nominal voltage is 3.0V.

CRP2, 2CR5 is actually a battery pack. There are two CR123A batteries inside, but there is a nice plastic frame on the outside. The two CR123A batteries connected in series make the voltage of CRP2 and 2CR5 reach 6V. The diameter of CRP2 is Ф35.0*19.5mm, the height is 36.0mm, and the nominal voltage is 6.0V. The diameter of 2CR5 is Ф34.0*17.0mm, the height is 45.0mm, and the nominal voltage is 6.0V.

CRV3, CRV6 battery, also lithium-manganese dioxide battery, is a battery pack composed of two batteries, CRV3 is a combination of two batteries in parallel, CRV6 is a combination of two batteries in series, and both lithium-manganese dioxides are newly launched variety that is used on digital cameras.

The CRV3 battery has a nominal voltage of 3.0V and a size of 14.5mm × 29mm × 52mm, and can be used instead of two AA alkaline batteries. But when you use it, you can look at the battery compartment, some can be put in, and some cannot be placed. This should be noted. The CRV6 battery has a nominal voltage of 6.0V and a size of 14.5mm × 29mm × 52mm. I haven't seen the actual product yet, so I can't tell you much about it.
