CR1220 battery

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

Different manufacturers, one physical battery. Voltage, chemistry and dimensions all match.
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.
