SpecsyModels and product details
Remember which battery each thing needs
Many batteries look almost identical but differ by a single digit or letter — and then they do not fit. CR2032, CR2025, LR44 and SR626SW are easy to mix up at the shelf.
Save the exact battery type and the device it belongs to in Specsy — and next time nothing has to be taken apart, remote, scales or sensor, just before the shop.

Button cells all look identical
A car key, a bathroom scale, a kitchen timer and a watch can all take near identical silver cells — with different numbers. And that number is usually printed on the battery itself in very small text.
By the time it dies the packet is long gone, and the old cell is easily lost among other similar ones.
Save the exact battery type in Specsy once — and the next replacement stops being a separate trip to the shop.
How to keep a battery card genuinely useful
- The exact battery code — best saved as a photo of the old cell before it goes for recycling
- The quantity — so you know at once whether one battery is needed or several
- A card of its own for safety devices — a smoke alarm or a carbon monoxide detector, each with its own reminder
- A reminder for the next check or replacement
- A note of where rechargeables are used — so disposables are not bought for them by mistake
The ones people mix up most
| Code | Common in | Confused with |
|---|---|---|
| CR2032 | Car keys, scales, motherboards | CR2025, which is thinner |
| CR2025 | Slim remotes, some keys | CR2032, which will not close the case |
| LR44 | Toys, laser pointers | SR44, the silver oxide version |
| SR626SW | Watches | Almost every other watch cell |
What belongs in a reminder rather than on the shopping list
- Smoke alarm batteries — set a recurring reminder for the same date every year
- Carbon monoxide detector — especially where the cell is sealed in and the life of the detector itself matters
- Thermostat batteries — so they are not remembered only once the heating has stopped working
- Door lock or keypad batteries — better replaced early than at the moment the device gives out completely
Questions people ask
Should this be one card or many?
Separate cards work better — one per device. You always start from the thing that has died: open the remote, the scales or the detector and the code, the quantity and the date of the last change are right there.
The print on the cell is tiny, what then?
Photograph it while it is out of the device, in good light. The photo enlarges, a used cell in a dark drawer does not.
What about rechargeable batteries?
Note the capacity in mAh as well as the size, since a low capacity cell will not run a high drain device well.
