Built around the real moment
Something stopped working. Let’s make it a five-minute problem.
Key fobs, watches, scales and remotes shouldn’t send you through a wall of near-identical codes. Start with the marking in your hand; CellMatch makes the differences clear.
At the kitchen tableIdentify the code before you order.
At the repair matConfirm chemistry, voltage and fit.
Why this is safer than a static chart
Fit is only one part of a correct match.
Cells that look identical can use different chemistry or drain profiles. CellMatch keeps those differences visible instead of hiding them inside a giant table.
Compare the chemistry
See whether the label means lithium, alkaline or silver oxide.
Confirm the dimensions
Match voltage, diameter and height with the manual or holder.

Evidence, not guesswork
Every prototype match starts with manufacturer guidance.
This is a validation prototype, not a substitute for the device manual. Always use the size and chemistry specified by the manufacturer. Keep coin cells away from children and never recharge a cell unless it is explicitly marked rechargeable.
