I remember Duracell had batteries with an indicator.
You could press it, and it would show how much was left in the battery.
It was a thermal strip that changed colour, so it emptied the batteries too,
increasing sales of course...
If you can make it cheap enough it may work., although few people will open
their car an look at the battery... In the dashboard..
do the majority of people even know what a battery *is*,
and if their car has one ???
Even my wife knows about the car battery, but nothing else. My
corolla has analog meter, but difficult to tell the exact reading.
Her Luxus does not even have analog meter. After her last dead
battery, she is well informed about monitoring the voltage. My meter
plugs into the cigarette socket. She will let me know if the reading
is below 11V. Just to be sure, I would probably wire a three color
led based on the battery voltage. She wouldn't ignore it if the color
turns yellow or red.
