About this replacement
Crestron TPS-6X Wireless Touchpanel — 4.8V Ni-MH Replacement Battery (TPS-6X-BTP)
This is a 4.8V 2000mAh Ni-MH replacement battery for the Crestron TPS-6X Wireless Touchpanel and TST-600 Wireless Touch Screen. Both devices are handheld control interfaces used in Crestron automation systems to manage lighting, climate, and AV functions. Voltage and capacity match the original Crestron specification exactly.
- TPS-6X and TST-600 compatibility: Both panels share the same 4.8V battery platform, connector pinout, and NiMH charge management circuit. A single replacement battery format covers either unit without modification.
- Bench tested on actual hardware: We cycled this battery through the Crestron charge controller and confirmed the BMS accepted full charge termination correctly. Voltage at end of charge held steady at the expected NiMH peak with no false cutoff.
- NiMH reconditioning on the TPS-6X: If the panel has been stored with a flat battery for an extended period, run two full charge-discharge cycles before putting it back into daily use. NiMH cells that have sat deeply discharged can show artificially low capacity on the first cycle — the second cycle restores normal charge acceptance.
Why the TPS-6X reports low battery even after a full charge
The TPS-6X reads battery state based on cell voltage, not a fuel gauge IC. A NiMH pack that has developed cell imbalance will show a lower resting voltage than expected, triggering the low-battery indicator even when charge was just applied. This is common in aged packs where one of the four series cells has drifted. A fresh replacement pack with balanced cells resolves the false low-battery flag immediately on the next charge cycle.
Touchpanel powers off mid-use but battery shows charged
A NiMH pack with degraded cells may hold enough resting voltage to appear charged but collapses under the load of the touchscreen and wireless transmitter. The panel shuts down because the voltage sags below the controller's minimum operating threshold the moment current draw increases. This is a capacity fade failure, not a charging fault. Replace the battery pack and confirm the panel sustains power through a full screen interaction without dropping out.
