Estry standard battery 750mAh 3.6V Ni-Cd for Siemens Opthalmoscope Pre-Vista CJB-1

Direct replacement for Siemens Opthalmoscope

This 750mAh 3.6V Ni-Cd battery matches the original specifications for the Siemens Opthalmoscope Pre-Vista CJB-1. It delivers 2.7Wh of energy in a single pack weighing 114.0g. The cell measures 73.3 x 28.5 x 25.7mm to fit the device compartment exactly. It is intended for clinicians and technicians who need a reliable power source for this specific instrument.

Certified safety protections and compliance marks

The pack integrates overcharge, over-discharge, over-voltage and short-circuit protection circuits to extend usable life. It carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications confirming quality management and hazardous-substance compliance. These credentials mean the battery meets recognized safety and environmental standards for medical-device accessories. No additional software or accessories are included in the package.

Ni-Cd chemistry constraints and fixed voltage

Nickel-cadmium chemistry exhibits memory effect if repeatedly recharged before full discharge, so periodic deep cycling is advised. The nominal 3.6V output is fixed and cannot be adjusted for other equipment. Self-discharge is higher than modern lithium alternatives, requiring more frequent top-up charges during storage. The cell is not suitable for devices that demand a different voltage or chemistry.
