CR2032 vs CR2025 vs CR2016
All three are 20mm, 3V lithium coin cells — but they differ in height. The CR2032 is the tallest of the three, so it only fits holders designed for a 3.2mm cell. Check your device's battery bay before swapping.

What batteries are equivalent to the CR2032?
The CR2032 is interchangeable with any cell of the same diameter, thickness and voltage, so an equivalent can be substituted without changing the device. Buyers look these cells up under three numbering systems at once — IEC, ANSI and manufacturer codes — and the list below covers the names the CR2032 is sold under.
Look any number up in the cross-reference tool → — type the marking on your cell and see where it lands, or pick your device and see the cells we supply for it.
Same cell, other designation or brand code — direct replacement

Fits the holder, different chemistry — not a like-for-like swap
Energizer's own note on its coin cells is the one to keep in mind: coin lithium batteries are not interchangeable, because both the diameter and the thickness vary with the cell designation — fit the designation your device specifies.
| Number on the cell | Published by |
|---|---|
| BR2032 | Energizer CR2032 product page lists BR2032 in its replacement list · Renata and Maxell both print this size as “CR/BR2032” — BR is lithium carbon monofluoride (Li-CFx), not lithium manganese dioxide: same 20.0 × 3.2 mm can, different discharge curve and usually lower capacity |
Same diameter, thinner cell — contact depends on the holder
A thinner cell of the same diameter drops into many holders, but the contact pressure comes from the holder's spring. If the device specifies CR2032, fit CR2032.
| Number on the cell | Published by |
|---|---|
| CR2025 | IEC 60086 size designation, 20.0 × 2.5 mm — 0.7 mm thinner than CR2032; 170 mAh typical against our CR2032's 190–255 mAh |
| CR2016 | IEC 60086 size designation, 20.0 × 1.6 mm — 1.6 mm thinner than CR2032; 100 mAh typical |
Where is the CR2032 battery used?
The CR2032 is used in car key fobs, motherboard cmos, electronic scales and other compact devices that draw small currents over long periods. Its 3.0V output and 190mAh ~ 255mAh capacity suit equipment that has to run for months without a battery change. The blocks below set out what to check for each device type.
CR2032 in Car Key Fobs
Most modern car key fobs and remote controls run on a CR2032 coin cell. Nissan, Honda and Toyota remotes commonly use the CR2032 (check the exact cell printed inside before ordering). When the range drops, the fob battery is usually the first thing to change.
CR2032 for Motherboard CMOS
The motherboard CMOS battery keeps your BIOS settings and system clock powered when the PC is off. Many desktop boards and laptops use a CR2032 — a dead cell is the usual cause of a "wrong system time" or lost BIOS settings on boot.
CR2032 for Apple AirTag
The Apple AirTag runs on a removable CR2032 coin cell. To replace it: press and twist the back cover open, swap the old cell for a fresh CR2032, then re-seat the cover. A new CR2032 keeps your AirTag powered and alerts you when it gets low.
What do buyers ask about the CR2032 battery?
Need the CR2032 priced, or the same cell printed and packed under your own brand? Send the quantity, the target market and the packaging format, and we return price, MOQ band and the CR2032 data sheet.
