CR927 batteries are also known as DL927, DL927B, BR927, BR927-1W, CR279-1W, LM927, 5011LC, ECR927 and KCR927, depending on which battery company manufactures this particular size and voltage. The designation CR927 refers to the chemical composition, height and diameter of the battery. CR927.com notes that CR means it is lithium manganese dioxide, 9 refers to 9.5 millimeters in diameter and 27 denotes 2.7 millimeters thick. CR927 batteries have three volts each.Know More
Batteries that are the same voltage as the CR927, but not necessarily the same size, include 2032, 2450, 2025, and 2430 batteries. The numbers indicate different heights and thicknesses, even though the voltage of the batteries are the same. For instance, a 2032 battery is 2.0 millimeters wide and 3.2 millimeters thick, yet it is three volts like the CR927.
Due to the small sizes of CR927 batteries, they are often sold in quantities of 5, 10, 25, 50 and 100. Manufacturers include Panasonic, Duracell, Energizer, Rayovac, Sanyo and Vinnic. According to Mega Batteries, batteries of this size are so small, they are called "coin cells."
The shelf life of these non-rechargeable batteries is between 7 to 10 years, and they are used in blinking jewelry, calculators, flashing toys, watches, glow-in-the-dark jewelry, car starters, garage door openers and computer memory backup.Learn more about Electricity
Use a coin cell battery cross reference chart when cross-referencing a CR2032 watch battery. Locate any cell on the chart containing the CR2032 battery; every other battery on the same row is compatible with the CR2032.Full Answer >
Common types of batteries include zinc-carbon, alkaline, lithium-ion and lead-acid batteries. Zinc-carbon and alkaline batteries are most often used as small household batteries. Lithium-ion batteries are used in rechargeable devices such as cell phones and laptops, while lead-acid batteries are most often used in vehicles.Full Answer >
Button cell batteries that are used in hearing aids, cameras and watches are considered single-use and therefore recharging should not be attempted. Lithium ion coin cell batteries, which are larger and flatter than button cell batteries, can be recharged.Full Answer >
Alkaline AA batteries are rated 1.5 volts, while NiMH AA batteries are rated at 1.2 volts. NiMH generally refers to a battery being rechargeable and to the materials from which the battery is constructed.Full Answer >
