Is 5012LC the same as CR1220?

Yes. 5012LC is another code for the same cell: lithium (Li-MnO2), 3 V, 12.5 × 2 mm.

Is DL1220 the same as CR1220?

Yes. DL1220 is another code for the same cell: lithium (Li-MnO2), 3 V, 12.5 × 2 mm.

Can I use BR1220 instead of CR1220?

Usually works in low-drain devices like memory backup, scales and remotes. BR cells cope better with heat but give less pulse current, so CR is the safer pick for key fobs and LED devices.

Will CR1216 work in place of CR1220?

Same 12.5 mm diameter, but 1.6 mm tall instead of 2 mm. Only if the holder fits; thinner cells can lose contact.

Will CR1225 work in place of CR1220?

Same 12.5 mm diameter, but 2.5 mm tall instead of 2 mm. Only if the holder fits; thinner cells can lose contact.

Can I use LIR1220 instead of CR1220?

No. Rechargeable Li-ion: 3.6-4.2 V and far less capacity; only for devices built for it.

What voltage is CR1220?

CR1220 is a 3 V lithium cell with a typical capacity of 35–40 mAh.

CR1220 Battery Equivalent

CR1220 is the same cell as 5012LC, DL1220 and ECR1220, so any of those codes will fit; BR1220 is the same size in the other lithium chemistry.

About the CR1220 cell

Used in keychain LED flashlights, and in some digital cameras to keep the time and date function running even when the main battery is taken out of the camera.
