CR1220 vs CR2032
The CR1220 is a small 12.5mm 3V lithium cell used for compact devices. It is too small for a CR2032 holder — match the exact size on your old cell.
| CR1220 | CR2032 | |
|---|---|---|
| Diameter | 12.5mm | 20mm |
| Thickness | 2.0mm | 3.2mm |
| Voltage | 3V | 3V |
| Capacity | ~38mAh | ~220mAh |
What are the CR1220 battery characteristics?
These are the CR1220 performance figures we declare under EU Regulation 2023/1542: rated capacity and the maximum available duration under a standard continuous load. Real discharge performance depends on load, temperature and cut-off voltage, so the exact test conditions are stated underneath the table.
| Capacity | MAD |
|---|---|
| 38mAh / 0.114Wh | 750hours |
Capacity & MAD test condition: 62kΩ continuously to 2.0V @ 20±2℃
Shelf life: One year after delivery under normal storage, 98% of initial capacity maintained
EU Declaration No. TQ-EUDOC-CR1220-20260622 · Compliant with Regulation (EU) 2023/1542
What batteries are equivalent to the CR1220?
The CR1220 is interchangeable with any cell of the same diameter, thickness and voltage, so an equivalent can be substituted without changing the device. Buyers look these cells up under three numbering systems at once — IEC, ANSI and manufacturer codes — and the list below covers the names the CR1220 is sold under.
Look any number up in the cross-reference tool → — type the marking on your cell and see where it lands, or pick your device and see the cells we supply for it.
Same cell, other designation or brand code — direct replacement
| Number on the cell | Published by |
|---|---|
| 5012LC | ANSI designation for this size — Energizer CR1220 product datasheet, printed as “Designation: ANSI-5012LC, IEC-CR1220” (data.energizer.com) |
| ECR1220 | Energizer (own model) · Maxell cross-reference chart, Energizer Eveready column |
| DL1220 | Duracell (own code) · Maxell cross-reference chart, Duracell column |
| SB-T13 | Seiko (own code) · Maxell cross-reference chart, Seiko column — single source, treat as unconfirmed |
| CR1220 — the same code is printed by Maxell, Panasonic, Renata, Rayovac and Varta | Maxell cross-reference chart, which carries a column for each of those makers at this size |
Same diameter, thinner cell — contact depends on the holder
This size is where a 0.4 mm difference decides whether the device works: compartment tolerances are tight.
| Number on the cell | Published by |
|---|---|
| CR1216 | IEC 60086 size designation, 12.5 × 1.6 mm — 0.4 mm thinner than CR1220, so contact in a CR1220 holder is not guaranteed |
Where is the CR1220 battery used?
The CR1220 is used in motherboards, remote controls, small devices and other compact devices that draw small currents over long periods. Its 3.0V output and 38mAh (0.114Wh) capacity suit equipment that has to run for months without a battery change. The blocks below set out what to check for each device type.
CR1220 for Motherboard CMOS
The motherboard CMOS battery keeps your BIOS settings and system clock powered when the PC is off. Many desktop boards and laptops use a CR1220 — a dead cell is the usual cause of a "wrong system time" or lost BIOS settings on boot.
What do buyers ask about the CR1220 battery?
Need the CR1220 priced, or the same cell printed and packed under your own brand? Send the quantity, the target market and the packaging format, and we return price, MOQ band and the CR1220 data sheet.
Printed, blister-carded and boxed in our own plant, from 50 cartons per product line. Samples are available before a production run — tell us the device the cell goes into.
