Panasonic CR2477 3V Lithium Battery, High Capacity Coin Cell

Genuine Panasonic CR2477 3V lithium coin cell, the largest and highest-capacity of the common 3V button batteries. Built for devices that need years of runtime from a single cell, such as IoT sensors, trackers and medical electronics.

• Genuine Panasonic CR2477, 3V lithium (Li/MnO2) chemistry
• Approximately 1000mAh capacity, 24.5mm diameter x 7.7mm thickness
• Wide operating range around -30C to 60C, very low self-discharge for long standby life
• Fits IoT and LoRaWAN sensors, asset trackers, glucometers and medical devices, alarm and security sensors, and select car key fobs and remotes

Equivalents and cross-reference

CR2477 is interchangeable with DL2477 (Duracell), ECR2477 (Energizer) and KCR2477. A BR2477 is the carbon-monofluoride variant with a wider temperature range at slightly lower capacity, and fits the same devices in most cases.

Important: not a CR2032 substitute

Despite both being 3V, a CR2477 is not interchangeable with a CR2032. At 7.7mm it is more than twice the thickness of a CR2032 (3.2mm) and holds around four times the capacity, so it will not fit a CR2032 holder and a CR2032 will sit loose in a CR2477 slot. Always match the exact code your device specifies.

Common questions

• What uses a CR2477? High-drain or long-life devices: IoT sensors, asset trackers, security sensors, some medical monitors and larger key fobs.
• Is CR2477 the same as DL2477? Yes. DL2477 is Duracell's label for the identical 3V cell and swaps in directly.
• Can I use a CR2477 instead of a CR2032? No. They differ in thickness and capacity and are not physically interchangeable.
