Yes this will work fine charges to the voltage required 4.1 / 4.2 ...

There's a big future in reusing all lithium batteries , particularly laptops which contain 18650 cells which are convenient to handle . Lithium batteries are usually thrown when the capacity dips .... the cells still have most of their useful life left in them

Input power for the charging module is via usb (5v) , you can use a phone charger .

The module reduces this and charges your battery to 4.1/ 4.2 v
