CR2025 vs CR2032
CR2025 and CR2032 share a 20mm diameter and 3V output, but the CR2032 is thicker (3.2mm vs 2.5mm) with more capacity. If your device recess is less than 3.2mm, use a CR2025 — a CR2032 will not close.
| CR2025 | CR2032 | |
|---|---|---|
| Diameter | 20mm | 20mm |
| Thickness | 2.5mm | 3.2mm |
| Voltage | 3V | 3V |
| Capacity | ~165mAh | ~220mAh |
What are the CR2025 battery characteristics?
These are the CR2025 performance figures we declare under EU Regulation 2023/1542: rated capacity and the maximum available duration under a standard continuous load. Real discharge performance depends on load, temperature and cut-off voltage, so the exact test conditions are stated underneath the table.

| 165mAh / 0.495Wh | 800hours | 14.0hours |
| 170mAh / 0.51Wh | 850hours | 15.0hours |
| 185mAh / 0.555Wh | 900hours | 16.0hours |
Capacity & MAD test condition: 15kΩ continuously to 2.0V @ 20±2℃
Application-Electronic key: 10mA 5s on, 55s off 24h/day to 1.8V @ 20±2℃
Shelf life: One year after delivery under normal storage, 98% of initial capacity maintained
EU Declaration No. TQ-EUDOC-CR2025-20260622 · Compliant with Regulation (EU) 2023/1542
What batteries are equivalent to the CR2025?
The CR2025 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 CR2025 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 diameter, different thickness — check the holder before substituting
The 20 mm family shares one diameter and differs only in height, which is what sets capacity and whether the compartment closes and makes contact.
| Number on the cell | Published by |
|---|---|
| CR2032 | IEC 60086 size designation, 20.0 × 3.2 mm — 0.7 mm thicker than CR2025, so it may stop a case or clip closing |
| CR2016 | IEC 60086 size designation, 20.0 × 1.6 mm — 0.9 mm thinner; 100 mAh typical |
Where is the CR2025 battery used?
The CR2025 is used in car key fobs, remote controls, motherboards and other compact devices that draw small currents over long periods. Its 3.0V output and 130mAh ~ 185mAh 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.
CR2025 in Car Key Fobs
Most modern car key fobs and remote controls run on a CR2025 coin cell. Nissan, Honda and Toyota remotes commonly use the CR2025 (check the exact cell printed inside before ordering). When the range drops, the fob battery is usually the first thing to change.
CR2025 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 CR2025 — a dead cell is the usual cause of a "wrong system time" or lost BIOS settings on boot.
CR2025 for Apple AirTag
The Apple AirTag runs on a removable CR2025 coin cell. To replace it: press and twist the back cover open, swap the old cell for a fresh CR2025, then re-seat the cover. A new CR2025 keeps your AirTag powered and alerts you when it gets low.
What do buyers ask about the CR2025 battery?
Need the CR2025 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 CR2025 data sheet.
Printed, blister-carded and boxed in our own plant, from 50 cartons per product line. Samples are available before a production run — tell us the device the cell goes into.
