Why doesn't the old gas stove have batteries?

The first one is ignited by piezoelectric ceramics.

This kind does not need a battery, but it has the advantages of slow ignition, low success rate, great environmental influence, and is not easy to catch fire when the environmental humidity is high.

Nowadays, electronic pulse is widely used in gas stoves, which has the advantages of stable ignition, fast ignition and high success rate. Gas stoves that use piezoelectric ceramics for ignition have now been eliminated.
