CR2320 battery

What replaces a CR2320
DL2320, ECR2320, BR2320
3 V lithium (primary), 23 × 2 mm (diameter × height)

The CR2320 is a single-use 3 V lithium (primary) coin cell. The codes below are the same physical cell sold under different manufacturer names, and any of them will fit.

Specification

IEC designation
CR2320
Nominal voltage
3 V
Chemistry
Lithium (primary)
Size
23 × 2 mm (diameter × height)
Typical capacity
135 mAh
Rechargeable
No — never charge it

Codes that mean the same battery

Different manufacturers, one physical battery. Voltage, chemistry and dimensions all match.
Code Fits?
DL2320 Yes — same cell
ECR2320 Yes — same cell
BR2320 Yes — same cell

Codes that look close but are not

Code Why it is not a substitute
CR2330 Same 23 mm diameter, 3.0 mm tall and roughly twice the capacity. Too thick for a CR2320 compartment.
CR2032 Three millimetres narrower. It will rattle in a 23 mm holder and may lose contact.

The CR2320 is a primary cell and must never be put in a charger. Charging a sealed primary battery builds gas pressure inside a can with no vent designed for it, which is how they rupture or catch fire. Rechargeable look-alikes exist for several sizes and carry different codes — check the code, not the shape.

Where it turns up

  • Memory backup in industrial controllers
  • Some Citizen and Seiko watch modules
  • Sports timing transponders
  • Older PDA and organiser backup cells

Common questions

What is equivalent to a CR2320?
DL2320, ECR2320, BR2320 — all the same 3 V cell under different manufacturer codes.
Can I use a CR2330 instead of a CR2320?
Same 23 mm diameter, 3.0 mm tall and roughly twice the capacity. Too thick for a CR2320 compartment.
Is the CR2320 rechargeable?
No. It is a primary cell — charging one risks rupture or fire. Rechargeable look-alikes exist in the same size under different codes.
