How Does a Battery Charger Work:

Recharging

• Batteries work because of the electrochemistry between an anode/negative terminal and a cathode/positive terminal. Some battery chemistries have the property of being chargeable, so that when electrical current is fed into them, the electrochemical discharge reaction reverses itself and the battery "recharges."
• Only some batteries have the chemistry and construction features that all them to be charged. Also, due to varying battery designs and chemistry, a given battery can only handle a certain voltage or amount of current. For example, the current fed into a lead-acid car battery would be very different from that of a lithium ion mobile phone battery.

Simple Chargers

• The most common type of charging device is the simple charger. Drawing electric current from a wall outlet, this provides either a constant voltage or constant current and will continue to feed it into the battery until unplugged. Usually a transformer of some kind is involved to convert the voltage. For example, American wall outlets work on the 110-volt standard, which is inappropriate if directly applied to a 12-volt battery.
• Most charging devices work on this model. They are cheap, but because they never stop feeding in electricity at a set rate and do not stop until unplugged from their power source, they can damage batteries with overcharging if left unattended.

Trickle Charging

Trickle charging is a variant of the simple charger in that it puts out a constant flow of electricity but at a very low rate. That rate is set to match the particular battery's decay or self-discharge rate. When the battery is completely recharged, the charging therefore continues only at the rate necessary to keep the battery charged and no more. This prevents overcharging and, therefore, degradation or damage to the battery, but makes the charging process very slow.

USB Charging

The USB bus on a computer is standardized with a 5-volt power output. Therefore, many computer accessories are designed to use USB outlets for battery charging. Excepting that it uses electricity drawn from a computer instead of directly from a wall outlet, it is similar to other charging methods.

Intelligent Charging

These chargers monitor either the time spent recharging, the temperature of the battery or the battery's voltage to determine when to autonomously terminate charging. This protects batteries from damage or degradation due to overcharging. Intelligent charging is becoming a popular charging feature for devices that use lithium ion batteries, as these are relatively expensive and suffer more degradation from overcharging than some other battery types.

About USB Plugs:

• Standard USB Plugs and Receptacles: The plugs and receptacles have 4-contacts and are rectangular in shape with the contact opening of a Type A plug or receptacle measuring approximately 13.1(W) x 5.5(H) mm. The contact opening on standard Type B USB plugs and receptacles measures approximately 5.6(W) x 3.2(H)mm.
• Mini-USB Plugs and Receptacles: Mini-USB plugs, receptacles and cables were primarily introduced for USB OTG (Universal Serial Bus On The Go) devices such as mobile phones, PDAs, digital cameras etc. The USB OTG specification allows a single port to act as either a host or a device - chosen by which end of the cable plugs into the socket on the unit. After the cable is connected and the units are synchronised, the units may even swap ends under program control. This ability targets units such as PDAs where the USB link might connect to a PC's host port with the PDA as a device or alternatively connect the PDA as a host  to a keyboard.
• Two small form factor plugs have been defined (Mini-A and Mini-B) along with a universal receptacle (Mini-AB) that accepts either a Mini-A plug or a Mini-B plug. . Mini-A, Mini-B, and Mini-AB connectors are identified easily by color. The specification nominates that the insulator plastic inside Mini-A plugs and receptacles is always white. In Mini-B connectors it's always black, and in Mini-AB receptacles it's always coloured grey. The plugs and receptacles have 5 contacts with contacts 4 & 5 joined together inside the Mini-A plug. Mini-USB plugs and receptacles are rectangular in shape, with the contact opening measuring approximately 6.8(W) x 3.1(H) mm
