is there any reason why it has to be battery ignition.
to be battery ignition it would have to be a very basic cooker as any ancillary parts are normally electric. even if it has an oven lamp would need to be plugged in
It just means I can replace my existing one’s setup like for like and not need to worry about plugging it into a nearby socket and have an unsightly cable about.
I’m not concerned about other ancillary functions like oven lamp or timer.
