CR2450 vs CR2032
The CR2450 is a larger, higher-capacity 3V cell (24.5mm x 5.0mm). It is not interchangeable with the CR2032 because the physical size is different — check your device's battery bay carefully.
| CR2450 | CR2032 | |
|---|---|---|
| Diameter | 24.5mm | 20mm |
| Thickness | 5.0mm | 3.2mm |
| Voltage | 3V | 3V |
| Capacity | ~620mAh | ~220mAh |
What are the CR2450 battery characteristics?
These are the CR2450 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.
| Capacity | MAD |
|---|---|
| 550mAh / 1.65Wh | 1450hours |
| 600mAh / 1.80Wh | 1500hours |
| 620mAh / 1.86Wh | 1550hours |
Capacity & MAD test condition: 7.5kΩ continuously to 2.0V @ 20±2℃
Shelf life: One year after delivery under normal storage, 98% of initial capacity maintained
EU Declaration No. TQ-EUDOC-CR2450-20260701 · Compliant with Regulation (EU) 2023/1542
What batteries are equivalent to the CR2450?
The CR2450 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 CR2450 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

Same size, different maker's part numbering
Renata sells this size as CR2450N. Ours is CR2450, 24.5 mm across and 5.0 mm high — check the height clearance in your holder, because 24.5 mm coin cells are also made 3.0 mm and 7.7 mm high and they are not interchangeable.
| Number on the cell | Published by |
|---|---|
| CR2450N / CR2450N-MFR | Renata's own part numbers for the 24.5 × 5.0 mm cell (renata.com) — the N is Renata's designation, not a different size |
Where is the CR2450 battery used?
The CR2450 is used in car key fobs, motherboards, sports watches and other compact devices that draw small currents over long periods. Its 3.0V output and 550mAh ~ 620mAh 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.
CR2450 in Car Key Fobs
Most modern car key fobs and remote controls run on a CR2450 coin cell. Nissan, Honda and Toyota remotes commonly use the CR2450 (check the exact cell printed inside before ordering). When the range drops, the fob battery is usually the first thing to change.
CR2450 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 CR2450 — a dead cell is the usual cause of a "wrong system time" or lost BIOS settings on boot.
What do buyers ask about the CR2450 battery?
Need the CR2450 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 CR2450 data sheet.
