An educational collaboration
The Curious Crew and Clarios built this book together, turning real battery engineering into a story children want to read twice.
There is a town where energy goes to work. Very few people have seen it.
Real engineering, hidden inside a story · Published in six languages · Available in bookstores globally

Watch the trailer.
Turn it. The town is on the outside.
This is the battery the story happens inside, the real one, modelled part for part. Drag it around, then open one of the four glowing points.




Four things hidden in the town
Tap a glowing point on the battery, or a line above, to open the page it comes from.
Step inside the town.

Read and play
A printed book, with a digital world behind its last page.
Battery Town is a book first: real pages to turn, pictures to linger over, a story shared with a parent or a teacher. A QR code in the back opens a free companion app that carries the same story further, with no shop and no account behind it.
We see the two as partners, not rivals. Reading builds the literacy every other subject rests on, and the app lets children meet new technology in a setting adults can trust. The book stays at the centre; the screen extends it rather than replacing it.
Read
A printed story to hold, turn and return to, read together or alone.
Play
Games and experiments in the free app, revisiting what the book explained.
Listen
The story narrated aloud, for children not yet reading on their own.
Real engineering
Checked by an engineer. Then read again by a lawyer.
One of them builds batteries for a living. The other spent a career weighing words for a living. The town is invented; nothing it teaches is.
“I felt a strong responsibility to ensure the battery-related content remained technically accurate while still being accessible to young readers. I was grateful that Nina Janjetović was open to several rounds of review.”

Meriem Akin
Platform Engineering Project Lead, Clarios EMEA
“Energy is the most present thing in a child's day and the least explained. Adults have a word for it: we say electricity, and we move on. Children don't move on. They ask where it came from. They ask where it went. They ask whether it's tired, whether it's hiding, whether it will come back.”
