Description
The Renata CR2477N is a high-capacity 3V lithium coin cell manufactured in Switzerland. Its relatively large 950mAh nominal capacity makes it suitable for compatible electronic equipment requiring longer operating life from a compact coin-cell format.
Renata specifies the CR2477N at 3V nominal voltage and 950mAh rated capacity. It uses Lithium Manganese Dioxide (Li/MnO₂) chemistry and measures approximately 24.5mm in diameter × 7.7mm high.
The product supplied by ArcEin is the individually packaged Renata CR2477N shown in the actual product photograph.

Common Applications
Use conservative application wording because compatibility should be determined by the equipment manufacturer:
- Memory backup systems
- Industrial electronic equipment
- Measuring instruments
- Sensors and monitoring equipment
- Security equipment
- IoT devices
- Electronic control systems
- Data logging equipment
- Other devices specifically designed for CR2477N
Important: Always check the existing battery or equipment manual for CR2477N before ordering.
CR2477N vs CR2477
This distinction is worth including because it can prevent incorrect orders.
Although CR2477N and CR2477 share the same nominal 24.5mm diameter and 7.7mm height designation, the “N” version has a modified case/terminal geometry. Customers should therefore not assume an ordinary CR2477 is a direct replacement for CR2477N.
For ArcEin, I would prominently display:
Please check your existing battery carefully. This product is CR2477N, not a standard CR2477.
Safety Information
The Renata CR2477N is a primary/non-rechargeable lithium battery.
Do not recharge, short-circuit, dismantle, crush, puncture or incinerate the battery. Install with correct polarity and only in compatible equipment.
Coin batteries must be kept out of reach of children. If swallowed or inserted into the body, seek immediate medical attention.
