What replaces a CR1220
DL1220, ECR1220, KCR1220, BR1220, 5012LC, SB-T13A
3 V lithium (primary), 12.5 × 2 mm (diameter × height)
The CR1220 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.

Codes that mean the same battery
| Code | Fits? |
|---|---|
| DL1220 | Yes — same cell |
| ECR1220 | Yes — same cell |
| KCR1220 | Yes — same cell |
| BR1220 | Yes — same cell |
| 5012LC | Yes — same cell |
| SB-T13A | Yes — same cell |
| L04 | Yes — same cell |
Codes that look close but are not
| Code | Why it is not a substitute |
|---|---|
| CR1225 | Same diameter, 2.5 mm tall instead of 2.0. It will not close a CR1220 compartment but the reverse swap leaves a CR1220 loose. |
| CR1216 | Same diameter, 1.6 mm tall, about two-thirds the capacity. |
The CR1220 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
- Digital watch modules and small fitness bands
- Keyless entry remotes on older cars
- Laser pointers and small LED torches
- Guitar tuners and electronic dartboards
Common questions
- What is equivalent to a CR1220?
- DL1220, ECR1220, KCR1220, BR1220, 5012LC, SB-T13A, L04 — all the same 3 V cell under different manufacturer codes.
- Can I use a CR1225 instead of a CR1220?
- Same diameter, 2.5 mm tall instead of 2.0. It will not close a CR1220 compartment but the reverse swap leaves a CR1220 loose.
- Is the CR1220 rechargeable?
- No. It is a primary cell — charging one risks rupture or fire. Rechargeable look-alikes exist in the same size under different codes.
