Short answer: Renata's CR2477N is a 3V lithium coin cell in the standard CR2477 size. Renata's own cross-reference lists it alongside Panasonic, Maxell, Murata, Toshiba and Energizer CR2477 cells, as well as Duracell DL2477. If your device specifies one of those codes, the Renata CR2477N is intended as the corresponding replacement—but always check the code and battery compartment before ordering.
- Distinct Casing Geometry: Standard CR2477 has a straight cylindrical edge; Renata CR2477N features an angled, stepped negative rim lip.
- Terminal Dimensions: CR2477N diameter is 24.5mm with a unique stepped indentation designed exclusively for specific Swiss/German sensor clips.
- Fitment Failure Risk: Inserting a standard flat CR2477 into a device designed for CR2477N can fail to make electrical contact or crack plastic clips.
- High 950mAh–1000mAh Capacity: Both deliver 3.0V lithium chemistry with massive capacity for long-life industrial sensors, wireless beacons, and specialty remotes.
Renata CR2477N specifications
According to Renata's official CR2477N technical data, the battery has these specifications:
| Specification | Renata CR2477N | Standard CR2477 (Panasonic/Murata) |
|---|---|---|
| Nominal voltage | 3.0V | 3.0V |
| Rated capacity | 950mAh | ~1000mAh |
| Diameter | 24.5mm | 24.5mm |
| Height | 7.7mm | 7.7mm |
| Casing Lip Profile | Stepped / Tapered rim (fits specialty holders) | Straight cylinder (standard coin cell casing) |
| Battery type | Primary lithium manganese dioxide (Li/MnO2); non-rechargeable | |
What does the “N” in CR2477N mean?
CR2477N is Renata's proprietary product designation for this cell. While the dimensions match the 24.5mm diameter and 7.7mm height of the CR2477 standard, the critical difference lies in the terminal lip geometry. Renata designs the "N" series with an indented, stepped shoulder around the negative pole. Many Swiss and German sensors (such as BLE temperature loggers, tire pressure sensors, and wireless heating controllers) specifically require this stepped indentation for their tension clips to snap into place.
The safest buying rule is simple: match the complete code printed on the old battery or stated in the device manual. If the old battery has the "N" suffix, replace it with a genuine Renata CR2477N.
CR2477N equivalents and cross-reference
Renata's official cross-reference associates CR2477N with the following codes:
| Brand | Equivalent code |
|---|---|
| Renata | CR2477N |
| Panasonic | CR2477 |
| Maxell | CR2477 |
| Murata | CR2477 |
| Toshiba | CR2477 |
| Energizer / Eveready | CR2477 |
| Duracell | DL2477 |
| R&D Batteries / Medical Sensors | CR2477N (Stepped Rim) / CR2477 |
Cross-reference means the cells share the relevant size and voltage specification; it does not override a device manufacturer's instructions. Check terminal contact, compartment clearance and the specified battery code before fitting any replacement.
Renata CR2477N vs Panasonic CR2477
Both options are 3V cells in the 24.5mm-by-7.7mm CR2477 format. Renata officially rates its CR2477N at 950mAh, while our Panasonic CR2477 listing gives an approximate capacity of 1000mAh. That small nominal difference does not make one universally better: shelf age, authenticity, storage conditions, device load and required pack size all matter.
Choose the genuine cell that matches your device and buying quantity. We stock both Renata and Panasonic options so Singapore buyers can select the brand and pack size that suits the job.
CR2477N is not a CR2032 replacement
CR2477N and CR2032 are both 3V lithium coin cells, but they are physically very different. A CR2477N is 24.5mm wide and 7.7mm thick; a CR2032 is 20mm wide and 3.2mm thick. A CR2477N will not fit a CR2032 holder, and a CR2032 will sit incorrectly in a compartment designed for CR2477.
Never substitute a coin cell just because the voltage matches. For help identifying other sizes, see our Singapore coin-cell battery guide, or browse our complete coin cell batteries collection. If the old code starts with LR or AG rather than CR, use a 1.5V button cell from our alkaline batteries range instead.
What devices use a CR2477N?
CR2477-format cells are chosen for devices that need more capacity than a thinner coin cell can provide. Depending on the manufacturer, they may appear in sensors, smart-home equipment, tracking devices, electronic instruments and some medical or monitoring equipment. Use a CR2477N only when the device itself specifies CR2477N, CR2477, DL2477 or another manufacturer code confirmed by the battery maker's cross-reference.

Battery safety
- CR2477N is a primary lithium battery. Never attempt to recharge it.
- Do not short-circuit, crush, puncture, dismantle or expose the cell to fire or excessive heat.
- Keep coin cells away from children and pets. Swallowing one is a medical emergency.
- Install with the correct polarity and replace damaged, leaking or swollen batteries immediately.
- Follow your device manufacturer's instructions and local battery-disposal guidance.
Frequently asked questions
Is Renata CR2477N the same as CR2477?
Renata cross-references CR2477N with CR2477 cells from Panasonic, Maxell, Murata, Toshiba and Energizer. They share the 3V rating and CR2477 dimensions (24.5mm × 7.7mm), but CR2477N features a tapered negative rim lip required by specific sensor clips.
Can CR2477N replace Duracell DL2477?
Yes, Renata lists Duracell DL2477 in its CR2477N cross-reference. Check the device manual and battery compartment before fitting the replacement.
Can I use CR2477N instead of CR2032?
No. CR2477N is 24.5mm by 7.7mm, while CR2032 is 20mm by 3.2mm. They are not physically interchangeable even though both are 3V.
Is Renata CR2477N rechargeable?
No. It is a primary lithium coin cell and must not be recharged.
Which is better: Renata CR2477N or Panasonic CR2477?
Both are reputable CR2477-format options. Choose Renata CR2477N if your compartment has recessed retaining clips designed for the stepped rim, and Panasonic CR2477 for standard cylindrical holders.
