Abstract :
Gadgets definitely require a battery, it can serve as an energy source. Overcharge
is a condition when the charging process is continued even if the battery condition
is full 100%. On rechargeable batteries, the active cells are reversible. When the
supply voltage to the battery is not disconnected, while the active cells in the
battery have been fully charged 100%, then the electricity that passes will not fill
the cells again but will be released as heat. That is why, if charging is too long,
the battery and the phone will feel hot. Anti-overcharge works to cut the charging
line of the gadget when it's full 100%, It?s work when the gadget is alive, it?s
means battery condition not in 0%, more suitable for use on mobile phones in this
case is handphone and there are some 3G class smartphones. However, it is not
suitable for the 4G class, due to the 4G class already has an Anti-overcharge
already embedded in the gadget. Conclution is cherged with Anti-overcharge fast
5 minutes than without it and the voltage condition and charging speed is more
stabil than without Anti-overcharge
