Replacement battery for Sena headsets

This Estry 10U-HR-01 lithium cell replaces the original battery in Sena 10U-HR-01, SC-HR01 and 10U-AR-01 communication units. It is built to the same 3.7V 80mAh specification and carries ISO9001, RoHS, CE, UN38.3 and MSDS certification. Riders who need a fresh power source for those specific headsets will find a direct match.

Capacity and voltage match the original

The single figure that decides fitment is the 80mAh capacity at 3.7V, which equals 0.3Wh. If the original pack is marked YP401225P and shows those exact ratings, this cell is electrically compatible; any other capacity or voltage means it is not the correct part.

Small connector requires careful handling

The pack measures 26.0 by 11.74 by 4.2mm and weighs 27.4g, so it slips into the tight headset cavity. Installation means opening the unit, disconnecting the old JST-style plug and seating the new one without bending the fragile pins; the most common mistake is forcing the connector the wrong way round.

Questions about this item

How long will the 80mAh capacity run my Sena headset in real use?

The 80mAh cell delivers 0.3Wh at 3.7V, matching the original runtime for the 10U-HR-01, SC-HR01 and 10U-AR-01 headsets

What connector standard does the YP401225P pack use and what does it limit?

The pack uses the proprietary Sena connector keyed to the 10U series; it limits voltage to 3.7V and capacity to 80mAh by design

Will the 26.0 x 11.74 x 4.2mm dimensions fit the battery bay without modification?

Yes, the 26.0 x 11.74 x 4.2mm footprint and 27.4g weight are identical to the OEM YP401225P, so it seats directly in the 10U-HR-01, SC-HR01 and 10U-AR-01 compartments
