CR927 batteries are also known as DL927, DL927B, BR927, BR927-1W, CR279-1W, LM927, 5011LC, ECR927, and KCR927, depending on the manufacturer of this size and voltage. The designation CR927 indicates the battery’s chemical composition, height, and diameter. CR927.com explains that CR stands for lithium manganese dioxide, 9 for 9.5 millimetres in diameter, and 27 for 2.7 millimetres in thickness. Each CR927 battery has three volts.
The batteries 2032, 2450, 2025, and 2430 have the same voltage as the CR927, although not necessarily the same size. The numbers reflect varying heights and thicknesses, despite the fact that the batteries have the same voltage. A 2032 battery, for example, is 2.0 millimetres broad and 3.2 millimetres thick, although it has the same voltage as a CR927 battery.
CR927 batteries are frequently marketed in quantities of 5, 10, 25, 50, and 100 due to their modest sizes. Panasonic, Duracell, Energizer, Rayovac, Sanyo, and Vinnic are among the manufacturers. According to Mega Batteries, these batteries are so compact that they are referred to as “coin cells.”
These non-rechargeable batteries have a shelf life of seven to ten years and are used in jewellery that blinks, calculators, flashing toys, watches, jewellery that glows in the dark, car starters, garage door openers, and computer memory backup.
