Compatible Replacement Battery

The Estry MDR-RF995 is a Ni-MH rechargeable pack built to match the original specifications for Sony MDR-RF995, WH-RF400 and MDR-RF995RK wireless headphones. It replaces part number BP-800-11 and delivers 2.4V with a 700mAh capacity for 1.68Wh of energy. The cell measures 46.5 x 23.3 x 11.9mm and weighs 47.3g.

Voltage and Capacity Match

The decisive specification is the 2.4V 700mAh rating, which must match the original pack exactly for the headphones to charge and report battery level correctly. A different voltage or capacity will cause charging errors or reduced runtime. The pack includes overcharge, over-discharge, over-voltage and short-circuit protection circuits.

Suitable for Direct Replacement

This battery suits owners of the listed Sony models who need a direct drop-in replacement with the original connector and form factor. Buyers whose headphones use a different voltage, capacity or physical layout should look elsewhere, as will anyone needing a higher-capacity pack for extended listening sessions.

Questions about this item

How long will the 700 mAh capacity actually run my MDR-RF995 headphones?

Runtime depends on the headphone's current draw; the 700 mAh rating means it can supply 700 milliamps for one hour, so divide 700 by the device's draw in milliamps to estimate hours.

What does the 2.4 V rating mean for compatibility with the WH-RF400?

The pack delivers a nominal 2.4 V, matching the original BP-800-11 specification, so it fits the voltage window the WH-RF400 charging circuit expects.

Will the 46.5 x 23.3 x 11.9 mm pack fit inside the MDR-RF995RK battery compartment?

Yes, those are the exact dimensions of the original BP-800-11 cell, so it slides into the MDR-RF995RK compartment without modification.
