Q:

What batteries are equivalent to a Cr927?

A:

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.

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.

  • Q:

    How can button cell batteries be recharged?

    A:

    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.

  • Q:

    How do I wire two 12-volt batteries together?

    A:

    Wiring two 12-volt batteries together depends on the application it needs to be used in. If double the voltage from 12 to 24 volts is needed , the batteries are wired in series (negative, positive wired to negative, positive). If 12 volts are needed, the batteries are wired in parallel (positive wired to positive and negative wired to negative).

    What is a change from one form of energy into another?

    A:

    The change of one energy type into one or more other energy type(s) is energy transformation, also known as energy conversion. The law of conservation of energy asserts that energy cannot be destroyed, merely transformed from one type of energy to another.

  • Q:

    How do you calculate linear feet?

    A:

    A linear foot, otherwise known as a lineal foot, is equivalent to any one-foot length of a long object, and there is no difference in length between one linear foot and one foot. Particular industries, such as construction and archiving, use the term linear foot to avoid confusion with the square foot or cubic foot.
