Direct Replacement Battery

The Estry CJB-191 is a nickel-cadmium cell rated at 3.6V and 750mAh for 2.7Wh of energy. It matches the original part specifications and fits devices that require this exact model number. The pack contains a single unit ready for installation.

Steady Output Under Load

Nickel-cadmium chemistry delivers a stable voltage curve during continuous discharge rather than a sharp drop-off. Overcharge, over-discharge, over-voltage and short-circuit protection circuits guard the cell through repeated cycles. The 750mAh capacity supports extended run times for compatible equipment.

Certified Build and Fit

The housing measures 73.3 by 28.5 by 25.7mm and weighs 114.0g, matching the original footprint for secure seating. Certifications include ISO9001, RoHS, CE, UN38.3 and MSDS for safety and environmental compliance. Buyers needing a different voltage, chemistry or form factor should verify their device requirements before ordering.
