Replacement Ni-MH battery for Estry devices

This 6.0 V, 4200 mAh nickel-metal hydride pack replaces the original BP-722 cell in a long list of Estry models including the ES280, ES170, UC8000 and UC15. It delivers 25.2 Wh of energy and is built to the same electrical specifications as the factory unit. The pack carries ISO9001, RoHS, CE, UN38.3 and MSDS certification for safety and environmental compliance.

Simple drop-in installation with model verification

The battery fits directly into the device's existing compartment without tools or soldering. Before purchase, confirm the exact model number and the BP-722 part number printed on the original cell to avoid mismatches. Incorrect model selection is the most common reason for fitment problems or charging errors after installation.

Ni-MH chemistry limits compared to newer types

Nickel-metal hydride cells have lower energy density than lithium-ion alternatives, so runtime per gram is modest at 402.0 g. They exhibit a gradual voltage drop during discharge rather than a flat curve, which can cause early low-battery warnings in some equipment. The pack is not suited for applications that require high peak currents or rapid recharge cycles beyond the charger's design.
