Replacement battery for Sony headsets

This nickel-zinc pack replaces the original BP-HP800-11 cell in Sony MDR-RF995, MDR-RF995RK and WH-RF400 wireless headsets. It delivers 700mAh at 2.40V and measures 46.50 x 23.30 x 11.90mm so it fits the existing battery compartment.

Voltage and capacity limits

The pack is rated at 2.40V and 700mAh, giving 1.68Wh of energy. The headset charging circuit expects exactly this voltage; using a higher-voltage cell would damage the device. Runtime scales with the 700mAh rating and will fall as the nickel-zinc chemistry ages through charge cycles.

Installation and common issues

The battery connects via the original plug; alignment must be exact or the headset will not power on. A new cell needs two or three full charge and discharge cycles before reaching rated capacity. Low-quality third-party chargers can shorten life, and the pack must not be exposed to temperatures above 60°C.

Questions about this item

Is this the only capacity available for the Sony MDR-RF995RK headset?

This replacement is offered in a single 700mAh capacity matching the original BP-HP800-11 specification.

What does the 700mAh rating actually deliver in daily use?

It restores the factory runtime for the MDR-RF995, MDR-RF995RK and WH-RF400 wireless headsets.

Does the 2.4V nickel-metal hydride chemistry limit charging options?

The pack uses the same 2.4V Ni-MH chemistry as the original, so it charges through the headset's standard dock or cable.
