What replaces a CR1225
DL1225, ECR1225, BR1225, KCR1225, 5020LC, SB-T13
3 V lithium (primary), 12.5 × 2.5 mm (diameter × height)

The CR1225 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?
DL1225 Yes — same cell
ECR1225 Yes — same cell
BR1225 Yes — same cell
KCR1225 Yes — same cell
5020LC Yes — same cell
SB-T13 Yes — same cell

Codes that look close but are not

Code Why it is not a substitute
CR1220 Same diameter, half a millimetre thinner. It seats loosely and holds about a quarter less charge.

The CR1225 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

  • Motherboard and embedded-system clocks
  • Tyre pressure monitoring sensors
  • Electronic candles and small toys
  • Some Casio calculators

Common questions

What is equivalent to a CR1225?
DL1225, ECR1225, BR1225, KCR1225, 5020LC, SB-T13 — all the same 3 V cell under different manufacturer codes.
Can I use a CR1220 instead of a CR1225?
Same diameter, half a millimetre thinner. It seats loosely and holds about a quarter less charge.
Is the CR1225 rechargeable?
No. It is a primary cell — charging one risks rupture or fire. Rechargeable look-alikes exist in the same size under different codes.
