01 — THE PROBLEM

Your junk drawer
is lying to you.

01

The drawer of lies

Dead batteries living next to fresh ones. Nobody knows which is which. Nobody ever will.

02

The wrong-size shuffle

You need AA. You find AAA, a C, and a 9V from 2019. The remote stays dead.

03

The freshness guess

You hold a battery to your ear and shake it. That is not a test. That is a ritual.

02 — HOW IT WORKS

A book.
For batteries.

Hardcover. Foil-stamped. Opens flat to labeled, size-keyed slots — a D physically cannot sit in a C slot. Every cell clicks in with a spring-loaded contact and a retention clip.

SPREAD 1

AA · AAA

12 + 12 SLOTS

The everyday workhorses. Color-coded ends — blue for AA, orange for AAA — so you never grab wrong at a glance.

SPREAD 2

C · D

6 + 4 SLOTS

The big ones, for flashlights and toys that eat batteries for breakfast. Teal for C, violet for D.

BACK COVER

9V + Meter

2 WELLS · PRESS-TO-TEST

Two keyed 9V wells, plus the press-to-test meter. ±5% accurate, piezo-powered. Needs no batteries. Obviously.

03 — FAIR QUESTIONS

FAQ.

Is this a real product? +
Not yet. It’s a concept we’re testing. Your email is the vote that tells us to build it — a big enough list means it becomes real.
When will it ship? +
If the first-press list is big enough, we go to production. List members hear first — and get the numbered run before anyone else.
How much will it cost? +
No pricing yet. We’re measuring interest first, then we’ll price it honestly. First-press members hear the number before the public does.
What do I get for signing up? +
A numbered first-run copy with your name on the reservation list, launch-day priority, and exactly one email when it’s ready. No payment, no spam.
