Batteries can be sorted into 3 categories: lithium-ion battery, alkaline battery and nickel–metal hydride battery.
A lithium-ion battery (sometimes Li-ion battery or LIB) is a family of rechargeable battery types in which lithium ions move from the negative electrode to the positive electrode during discharge, and back when charging. Lithium-ion batteries are common in consumer electronics. They are one of the most popular types of rechargeable battery for portable electronics, with one of the best energy densities, no memory effect, and only a slow loss of charge when not in use.
Alkaline batteries are a type of primary batteries dependent upon the reaction between zinc and manganese dioxide(Zn/MnO2). A rechargeable alkaline battery allows reuse of specially designed cells. The alkaline battery gets its name because it has an alkaline electrolyte of potassium hydroxide, instead of the acidic ammonium chloride or zinc chloride electrolyte of the zinc-carbon batteries.
3A nickel–metal hydride cell, abbreviated NiMH or Ni-MH, is a type of rechargeable battery. It is very similar to the nickel–cadmium cell (Ni-Cd). NiMH use positive electrodes of nickel oxyhydroxide (Ni-OOH), like the Ni-Cd, but the negative electrode uses a hydrogen-absorbing alloy instead of cadmium. A NiMH battery can have two to three times the capacity of an equivalent size Ni-Cd, and their energy density approaches that of a lithium-ion cell.

3. Notes about battery
(1) All rechargeable battery’s voltage are 3.7V-4.2V. If batteries are series-connected, the total voltage should be added up. If batteries are paralleled-connected, the total voltage remains 3.7V-4.2V.
(2) All non-rechargeable batteries’ voltage are 3V.
(3) Alkaline batteries’ voltage are1.5V, Ni-MH batteries’ are 1.2V.
(4) Flashlight‘s brightness is subject to battery voltage.
(5) Battery Type conversion: AA=14500, CR123A=16340, CR123A*2=18650.
