Q:

How can button cell batteries be recharged?

A:

Quick 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

Button cell batteries have a single cell with a slow self-discharge that allows devices like watches to run continuously for extended periods of time. They are rated between 1.5 and 3 volts and are used in items that do not require high power.

Button cell batteries contain a number of heavy metals and are considered a single-use item that should discarded at designated facilities that support its proper disposal.

Coin cell batteries are often used as the backup for CMOS (complimentary metal-oxide semiconductor), which are the chips that store the time, date and hardware settings in computers, and they are available in rechargeable form.

    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 the difference between a cell and a battery?

    A:

    The difference between a cell and a battery is that a cell is a single unit that converts chemical energy into electrical energy, and a battery is a collection of cells. According to About.com expert Mary Bellis, each cell contains two electrodes and an electrolyte, a substance that reacts chemically with each electrode, generating an electrical current. Aggregating cells into a battery increases the electrical voltage they produce.

    How does a load cell work?

    A:

    Load cells are typically built using foil strain gauges that are resistively bonded to a metallic member. When the metallic member becomes stressed by the application of a force, a change in resistance occurs due to the resulting strain. This leads to a change in output voltage.

    What are dry cell car batteries?

    A:

    A dry cell car battery is a battery that contains a paste electrolyte and only enough liquid to promote conductivity. These batteries are not spillable and have a superior storage life when compared to wet cell car batteries.
