I heard the Bf-109 had an inertia starter system, but already see many footage of the plane being startup with a hand crank. Was wondering if the crank was used just for save battery.

Maybe. Many electrically-driven inertial starters had provision for a hand crank, some were hand crank only. Not sure which the 109 has. I've seen 190's spool up the inertial wheel manually and electrically.

The 109 is always hand-cranked afaik.
The 190 could be battery-cranked or cranked by ground-power.

Inertia Starter: a device for starting aero engines consisting of a large flywheel which is set in motion by hand or mechanical means. When the flywheel is turning rapidly it is suddenly connected to the engine and its momentum rotates the crankshaft.

The 109 had an inertia starter with a hand crank only, so manual start up was required each time. There was an electric starter for the DB 601/605, but I believe due to space issues it was not used for the engine, only on 110s.

Thanks for the info, Kurfy. I always thought both options were possible, maybe because too many restored warbirds are modified nowadays to have the flywheel spooled up with electric motor!
