CR2477N Lithium Button Cell Battery

The CR2477N is an original lithium coin cell battery from the Swiss quality manufacturer Renata and is used directly by industrial machine manufacturers. It provides stable 3V output, high energy density, and very low self-discharge, ensuring long service life and reliable performance in critical applications.

The battery is widely used in CNC controls, measurement systems, medical equipment, sensors, watches, and other precision devices where stable power supply and secure data retention are essential. CR2477N is known for consistent performance even in demanding industrial environments, making it ideal for service, maintenance, and preventive replacement.

The CR2477N is the exact original battery supplied by machine manufacturers and is used as an OEM battery in HEIDENHAIN 315878-01 and 315878-04, DMG MORI 2298405 and 22345430, as well as B&R 0AC201.91. The battery is manufactured by Renata and supplied without OEM packaging, but is technically identical to the batteries sold under the machine manufacturers’ spare part numbers. It can also be used as a replacement for Renata CR2450N.
