CR2320 battery: equivalents & specs

The CR2320 is a 3 volt lithium coin cell, 23 mm across and 2 mm thick, holding 110 to 130 mAh. The 23 mm family is far less common than the 20 mm sizes, and this thin member appears mainly in older instruments and memory backup roles.

Same battery, other names

Every code below is the exact same cell as CR2320. Any of them will fit and work identically.

  • CR2325: Same 23 mm diameter, 0.5 mm thicker; the more commonly stocked of the two.

Buying and replacement notes

If a device takes a 23 mm cell, it will be fussy about substitutes: nothing from the plentiful 20 mm family makes contact in its holder. The CR2325, half a millimeter thicker, sometimes fits the same spring-loaded holder and holds roughly half again the charge, about 190 mAh. Renata is the most dependable ongoing source for the 23 mm sizes.

⚠️ Keep away from children. Swallowed button batteries, especially 20 mm lithium coins, cause severe injury within hours. If a child swallows one, call the 24/7 National Battery Ingestion Hotline (US) at 800-498-8666 or poison control at 800-222-1222 immediately. What every parent should know.

Frequently asked questions

Can a CR2032 replace a CR2320?
No. The digits deceive: the CR2320 is 23 mm across and 2.0 mm thick, while the CR2032 is 20 mm and 3.2 mm. Neither fits the other's holder. The similarity in names causes frequent misorders, so read the code as diameter plus height.
Where are CR2320 batteries used?
Mostly older electronics: RAM backup in vintage computers and instruments, early remotes and some industrial controllers. Modern designs choose the 20 mm or 24.5 mm families, which is why the 23 mm sizes have become specialty items.
What can I substitute for a hard-to-find CR2320?
The CR2325 shares the 23 mm diameter and adds 0.5 mm of height; in a holder with spring contacts it often works and, at about 190 mAh, outlasts the original by a wide margin. Failing that, order the exact size from Renata or an electronics distributor rather than modifying the holder.
