Coin Cell Battery Cross Reference Chart & Specifications
Coin cell batteries (also called button cell batteries) power watches, key fobs, car remotes, BIOS chips, calculators, glucometers, electric candles, and thermometers. This chart covers 22 coin cell models, from the tiny CR927 to the high-capacity CR2477 (1000 mAh). The most common sizes are the CR2032, CR2025, and CR2016, all 20mm in diameter but at different heights. Every model listed here runs at 3 volts.
Brand names vary, but the battery is the same size. Duracell uses the DL prefix: DL2032 equals a CR2032. Energizer uses ECR, so ECR2032 is the same cell. Kodak uses KCR. The CR prefix means lithium manganese dioxide chemistry. The BR prefix (seen on BR2032, BR2025, and others) indicates lithium polycarbon-monofluoride, a slightly different chemistry packed into the same physical size.
PRO TIP: CR and BR batteries with the same size number are physically identical and interchangeable in most devices. If your device manual specifies one or the other, follow it; the difference matters mainly in extreme temperatures or high-precision medical equipment.

* Li-MnO2 or Lithium Manganese Dioxide is the primary chemistry for non-rechargeable coin cell batteries known for high energy density, long shelf life, and superior safety. They are widely used in consumer electronics, IoT devices, medical equipment, and security systems.
How to Read Coin Cell Battery Numbers
The number on a coin cell battery tells you its exact size. The first two digits are the diameter in millimeters. The last two digits are the height in tenths of a millimeter. A CR2032 is 20mm wide and 3.2mm tall. A CR2025 is the same 20mm diameter but only 2.5mm tall. A CR2016 is 20mm wide and just 1.6mm tall, too thin for a CR2032 slot.
The letter prefix identifies the chemistry. CR means lithium manganese dioxide (LiMnO2), the standard for most consumer devices. BR means lithium polycarbon-monofluoride (Li-CFx). Both deliver 3 volts. BR cells handle wider temperature ranges and self-discharge more slowly, which is why they show up in industrial and medical equipment. For everyday use in remotes, watches, and key fobs, CR and BR are interchangeable in most cases — but your device manual has the final word.
Brand prefixes are just marketing names. DL on a Duracell battery, ECR on an Energizer, and KCR on a Kodak all refer to the same underlying cell size. DL2032, ECR2032, and KCR2032 are all physically identical to a CR2032.
Common Coin Cell Battery Applications
The CR2032 is the most widely used coin cell. It powers PC and laptop BIOS chips (holding memory settings when the computer is off), key fobs, glucose meters, and many garage door remotes. At 220 mAh and 3.2mm thick, it has enough capacity for years of standby use in low-drain devices.
The CR2025 (165 mAh, 2.5mm thick) and CR2016 (90 mAh, 1.6mm thick) are common in thin car key remotes where the housing is too shallow for a CR2032. These three batteries share the same 20mm diameter, so the right choice comes down to which physically fits the battery compartment.
The CR1632 (125 mAh, 16mm diameter) appears in Toyota and Lexus key fobs, some Casio watches, and compact remotes. The CR1616 and CR1620 serve similar applications at lower capacities. For smaller devices (fitness trackers and micro remotes), the CR927 (9.5mm diameter) and CR1025 (10mm diameter) are frequent choices.
High-capacity cells like the CR2450 (620 mAh) and CR2477 (1000 mAh) power tire pressure monitoring sensors, medical devices, and smart home sensors that need years of life without a battery swap.
Frequently Asked Questions
Can I replace a CR2032 with a CR2025?
Sometimes, but not always. Both batteries are 20mm wide and output 3V, but the CR2025 is 2.5mm tall vs. 3.2mm for the CR2032. If the battery compartment has room for the thinner cell and the contacts still make solid contact, a CR2025 will work. The CR2025 holds 165 mAh vs. 220 mAh for the CR2032, so it will run out faster. If the compartment is sized specifically for the CR2032's thickness, the CR2025 may sit loose and cause intermittent power.
What does "CR" mean on a coin cell battery?
CR stands for lithium manganese dioxide chemistry (LiMnO2). Under the IEC naming standard, C designates lithium chemistry and R designates a round form factor. All CR coin cells output 3 volts nominal. The number after CR gives the dimensions: the first two digits are diameter in millimeters, and the last two are height in tenths of a millimeter.
Are DL2032 and CR2032 the same battery?
Yes. DL2032 is Duracell's model number for the CR2032. ECR2032 is Energizer's. KCR2032 is Kodak's. All share the same 20mm diameter, 3.2mm height, 3V output, and approximately 220 mAh capacity. The prefix is brand-specific. The number is the actual size designation that matters for compatibility.
Why won't my device work with a new coin cell battery?
A few common causes: the battery is installed upside down (positive side faces up in most coin cell slots), the contacts are corroded from an old battery, or the replacement is the wrong size. A CR2016 looks similar to a CR2032 but is half as thick — it will not work in a CR2032 slot. If the battery is the correct model and installed the right way, clean the contacts with a dry cotton swab before concluding the battery is bad.
What is the difference between CR and BR batteries?
CR batteries use lithium manganese dioxide chemistry. BR batteries use lithium polycarbon-monofluoride (Li-CFx). Both are 3V and come in the same physical sizes. BR cells have a flatter discharge curve, lower self-discharge, and better performance at temperature extremes down to -40°C. CR cells deliver slightly higher current on demand and cost less. For most consumer devices — remotes, watches, key fobs — the real-world difference is minimal.
How long do coin cell batteries last?
It depends on the device and how often it draws current. In a low-drain device like a watch or BIOS chip, a CR2032 can last 5 to 10 years. In a key fob used multiple times daily, expect 1 to 3 years. In a device that transmits data frequently (tire pressure sensor, smart home device), you may get 2 to 5 years depending on transmission frequency and temperature. Coin cells also lose charge slowly when not in use — most have a 10-year shelf life from the manufacture date.
Can I use a higher capacity coin cell battery in my device?
Only if it physically fits. A higher capacity rating within the same model number (one brand's CR2032 at 225 mAh vs. another at 200 mAh) just means longer runtime with no downside. But you cannot put a CR2450 in a CR2032 slot — the CR2450 is 24.5mm wide and 5mm tall vs. 20mm and 3.2mm for the CR2032. Always match the model number exactly. Capacity differences within the same model are fine and harmless.
