Hi,

can we charge the 3.7 v Li.Ion battery (mobile battery) by directly connecting the + and - wires from the commercial mobile chargers...?

Thank you.

If you mean under "mobile charger", wall trafo with 5V voltage output, of course not!

You need charger circuit for Li-Ion batteries.

Some types are simpler, but there is no battery that is charged by directly connecting to a commercial 5V mobile phone charger.
Unless you want it to go pop.
