This method is not applicable to new nimh batteries, may shorten the service life of nimh batteries.

At present mobile phone use lithium battery is divided into two kinds, lithium ion and lithium polymer. Two kinds of battery anode materials are the same, are generally cobalt acid lithium materials and lithium iron phosphate (ternary no physical) in the cell phone battery products, the difference lies mainly in lithium ion battery electrolyte is six lithium fluoride phosphate, lithium polymer battery is solid polymer electrolyte. Polymer battery basically characteristic of SONY Ericsson. Generally speaking, polymer battery discharge more even, safety performance is better, but the cost is higher
