External Battery Charger

A battery charger is a device used to put energy into a secondary cell or rechargeable battery by forcing an electric current through it. And a rechargeable battery, storage battery, or accumulator is a type of electrical battery. It comprises one or more electrochemical cells, and is a type of energy accumulator. It is known as a secondary cell because its electrochemical reactions are electrically reversible. So, different charger is necessary to you. Samsung I9300 Charger is one of the most popular charger in the market.

You may ask that how they works. The charging protocol depends on the size and type of the battery being charged. Some battery types have high tolerance for overcharging and can be recharged by connection to a constant voltage source or a constant current source.Mobile Portable Charger of this type require manual disconnection at the end of the charge cycle, or may have a timer to cut off charging current at a fixed time.

Other battery types cannot withstand long high-rate over-charging; the charger may have temperature or voltage sensing circuits and a microprocessor controller to adjust the charging current, and cut off at the end of charge. A trickle charger provides a relatively small amount of current, only enough to counteract self-discharge of a battery that is idle for a long time. Slow battery chargers may take several hours to complete a charge; high-rate chargers may restore most capacity within minutes or less than an hour, but generally require monitoring of the battery to protect it from overcharge. Electric vehicles need high-rate chargers for public access; installation of such chargers and the distribution support for them is an issue in the proposed adoption of electric cars. The example is Samsung N7100 Charger. It can enhances your mobile smart life and is a products for a richer and more enjoyable life.
