Compatible replacement battery

The Estry RR-3 is a nickel-metal hydride battery pack built to match the original specifications for Windmere RR-3 devices. It delivers a nominal voltage of 2.4V and a capacity of 2000mAh for reliable runtime. The pack measures 49.0 x 29.0 x 14.5mm and weighs 91.5g for a direct fit. Safety certifications include ISO9001, RoHS, CE, UN38.3 and MSDS.

Suitable for direct replacement only

This pack suits owners of Windmere equipment that requires the exact RR-3 form factor and 2.4V chemistry. It is not for users who need a different voltage, a higher capacity than 2000mAh, or a larger physical size. Buyers with devices that accept only proprietary smart batteries should look elsewhere.

Voltage and capacity define compatibility

The single specification that decides fit is the 2.4V 2000mAh rating combined with the stated dimensions. Only equipment designed for this exact voltage and capacity should use this pack.

Questions about this item

How long will the 2000mAh capacity actually run my device?

Runtime depends on the device's current draw; at a steady 200 mA load the pack would last roughly ten hours before reaching its 2.4V nominal cut-off.

Does the 2.4V rating match the original Windmere RR-3 pack exactly?

Yes, the replacement is built to the same 2.4V nominal voltage and 4.8Wh energy rating as the factory cell.

Will the 49.0 x 29.0 x 14.5mm pack fit the RR-3 battery compartment?

Those are the exact external dimensions of the original pack, so it slots into the same compartment without modification.
