Compatible Headset Battery

The Centenex Electronics DS-CS-TTR800SL is a direct replacement for TELEX BP-700NM and BP-800NM packs. It fits RKP-4, TR-1, TR-700, TR-800, TR-80N, TR-825 and TR82N wireless headsets. The 7.2V 2000mAh Ni-MH cell restores original run-time for broadcast and intercom crews who rely on these specific models.

Simple Drop-In Installation

The pack slides into the headset battery compartment without adapters or wiring changes. Its black casing matches the original dimensions of 103.50 x 62.50 x 18.80 mm so the battery door closes securely. This frees technicians from sourcing proprietary OEM spares and keeps compatible headsets in service during live productions.

Low-Heat Ni-MH Operation

Nickel-metal hydride chemistry runs cool during typical talk-back duty and does not require active cooling. The 14.40Wh capacity supports extended sessions without the surface temperature rise seen in higher-density cells. There is no fan or pump, so the headset stays silent and the battery adds no audible noise to the user's ear cup.
