Most cookers with batteries are divided into two types: with flameout protection and without flameout protection.
The one with flameout protection uses two batteries (there are two needles on the fire cover), and the batteries consume a lot of electricity. Generally, the battery can only last for 3 to 6 months. There is a fire needle on the fire cover without flameout protection. It uses batteries, which are durable and can last for 6 months to 1 year.
In the past, some gas stoves did not use batteries, and its principle was the principle of electronic lighters. Piezoelectric effect elements are used to generate high voltage and sparks during impact. It can be used for tens of thousands of times and its service life can reach ten years.
