What this battery replaces

This Estry E06 BP-722 is a 6.0 V, 4200 mAh nickel-metal hydride pack built to the original dimensions of 89.78 × 46.92 × 40.74 mm and weighing 402.0 g. It carries ISO 9001, RoHS, CE, UN 38.3 and MSDS certification and includes over-charge, over-discharge, over-voltage and short-circuit protection. The energy rating is 25.2 Wh.

Who should buy this and who should not

Owners of devices that take the E06 model or BP-722 part number will find a direct-fit replacement with the same voltage and capacity as the factory cell. Buyers whose equipment requires a different voltage, a higher capacity or a lithium-based chemistry should look elsewhere.

The specification that decides fit

The 6.0 V nominal voltage and 4200 mAh capacity must match the values printed on the original battery or listed in the device manual; if either figure differs, this pack will not work correctly.

Questions about this item

How long will the 4200mAh capacity last under continuous load?

The 6.0V 4200mAh Ni-MH pack delivers 25.2Wh; run time depends on the device's current draw, so divide 4200mAh by your equipment's mA rating to estimate hours.

Does the pack run hot or make noise during all-day operation?

Ni-MH chemistry is silent and generates only modest warmth; the built-in overcharge, over-discharge, over-voltage and short-circuit protection helps keep temperature stable during extended use.

What connector or charger must I already own to use this BP-722 replacement?

It fits the E06 device directly; you only need the original E06 charger or a compatible 6.0V Ni-MH charger with the correct polarity for the BP-722 pack.
