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.

Cross Reference

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.

CR1220 is a 3.0V lithium manganese dioxide (Li-MnO₂) primary cell: it is not rechargeable and must never be charged. It is not the same as the rechargeable ML1220 / LIR1220 that fits the same holder — those must only be used in a device designed to charge them.

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 cellPublished by
CR1216IEC 60086 size designation, 12.5 × 1.6 mm — 0.4 mm thinner than CR1220, so contact in a CR1220 holder is not guaranteed

These tables are compiled from manufacturers' own cross-reference documentation. Equivalent numbers mean the cell will fit and operate in the same holder; capacity and discharge curve can still differ between brands and between chemistries, so confirm the specification for the device you are powering. Numbers marked "single source" appear in one manufacturer's documentation only — ask us and we will confirm on a sample.
Applications

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.

FAQ

CR1220 Battery FAQs

What is a CR1220 battery?

CR1220 is a 12.5mm diameter, 2.0mm thick lithium coin cell with 3.0V output and ~38mAh (0.114Wh) capacity.

What is the CR1220 compatible with?

ECR1220, 5012LC, DL1220 — same size and voltage, interchangeable with CR1220.

What is a CR1220 battery equivalent to?

ECR1220, 5012LC, DL1220 — these are the same 12.5mm x 2.0mm cell at 3.0V, sold under different manufacturer codes, so they fit and operate in any device that specifies a CR1220. Capacity and discharge curve can still differ between brands and chemistries.

Is the CR1220 rechargeable?

Standard CR1220 is a primary (non-rechargeable) lithium battery.

How long does a CR1220 battery last?

In a low-drain device (watch, CMOS, spare key fob) a CR1220 typically lasts several years; in high-drain use the cycle is shorter.

Does a CR1220 fit my device?

CR1220 fits any device that specifies a CR1220 cell or a listed compatible equivalent (ECR1220, 5012LC, DL1220).

How do I get CR1220 battery wholesale pricing?

Pricing depends on cell grade, quantity and packaging, so quotes are issued per project rather than from a fixed list. Send your quantity, target market and label or packaging requirements, and we return a landed-cost quote together with samples — usually within one working day.
