The battery in the razor can be replaced with another one. Lithium battery is a class of lithium metal or lithium alloy as a positive\/negative electrode material, the use of non-aqueous electrolyte solution of the battery. In 1912, the lithium metal battery was first proposed and studied by Gilbert N. Lewis. In the 1970s, M. S. Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical characteristics of lithium metal, the processing, preservation and use of lithium metal have very high environmental requirements.
It can be changed. It's been changed many times. First open the razor, note that some screw installation, some have a buckle installation, after opening to see the original battery model, specifications, voltage, generally marked, basically belong to the standard parts, shopping malls, online can buy. Electric soldering iron may be used when disassembling and replacing, and it should be noted that the welding time should not be too long, so as not to damage the battery or even cause an explosion.
You have to look at the parameters, is the same output voltage and current can be the same.
