CR2325 vs CR2320: the 23 mm coin cell pair

CR2325 vs CR2320

The CR2325 and CR2320 are 3 volt lithium coin cells, both 23 mm across. The CR2325 is 2.5 mm thick with about 190 mAh; the CR2320 is 2.0 mm thick with 110 to 130 mAh. In a holder with spring contacts they can sometimes swap. In a tight one they cannot.

The 23 mm family is a specialty size. You find it in memory backup circuits, older instruments and remotes, and ski pass transponders, not in the supermarket battery rack. Of the two, the CR2325 is the easier one to buy, largely because Renata keeps it in mainstream production. The thinner CR2320 is now mostly an order-online item.

The 0.5 mm difference is small enough that some holders tolerate either cell. If a CR2320 holder has a springy contact and room above the cell, a CR2325 often fits and outlasts the original, since it holds roughly half again as much charge. In a tight holder or a clamped backup socket it will not, so never force it. A CR2320 in a CR2325 holder sits 0.5 mm low and can lose contact under vibration, which in a backup role means a lost clock or settings. Treat that as a stopgap.

The names cause most of the wrong orders. A CR2032 looks like a near match on paper, but it is 20 mm across and 3.2 mm tall, so it will not sit properly in a 23 mm holder. For a CR2325 in a cold or hot location, the BR2325 is the same size in wide-temperature chemistry with a little less capacity.

Frequently asked questions

Can I use a CR2325 instead of a CR2320?

Sometimes. It shares the 23 mm diameter and is 0.5 mm thicker. Where the holder has a flexible contact and the cover closes without force, it works and lasts longer, with about 190 mAh against 110 to 130. In a tight socket it will not fit, so order the CR2320.

Can a CR2320 replace a CR2325?

Only as a stopgap. It fits the 23 mm holder but sits 0.5 mm short, so contact pressure is weaker and the connection can drop under vibration. It also holds noticeably less charge. Fit the correct CR2325 or the BR2325 as soon as you can.

Is a CR2032 the same as a CR2320?

No. The digits are similar, but a CR2032 is 20 mm across and 3.2 mm thick, while a CR2320 is 23 mm across and 2.0 mm thick. Neither fits the other's holder properly. Read the code as diameter first, then height.
