About this replacement
Tree DCT-50 — 7.4V Li-ion Replacement Battery (DCT-50-RB)
This is a 7.4V, 2600mAh Li-ion battery for the Tree DCT-50 digital scale. It replaces OEM part DCT-50-RB and restores full power to the scale's load cell amplifier and display circuit. If your DCT-50 is shutting down mid-use or holding a charge for noticeably less time than it once did, this is the direct swap.
- DCT-50 platform fit: The DCT-50 runs its load cell amplifier and backlit display from a single 7.4V Li-ion cell pack. This replacement matches that voltage rail and uses the same connector and BMS communication expected by the scale's power management circuit.
- Bench tested on actual hardware: We cycled this battery through the DCT-50's power-on sequence and confirmed the BMS handshake completes correctly — the scale powers on without fault codes and the load cell amplifier receives stable voltage across the operating range.
- Post-install warm-up on the DCT-50: After fitting this battery, power the scale on and wait 30 seconds before placing any weight. The DCT-50's load cell amplifier needs time to reach a stable operating voltage — readings taken in the first few seconds after power-on can drift by several grams until it settles.
Why the DCT-50 shows an error code immediately after a battery swap
Swapping the battery causes a full power cycle, and the DCT-50 loses its zero reference point in the process. The scale's firmware interprets the missing zero reference as an out-of-range load cell signal and throws an error. This is not a fault with the battery — it is the scale asking to be re-zeroed. Hold the tare button for three seconds with nothing on the platform to reset the zero and clear the error.
DCT-50 not entering auto-off after a battery replacement
The DCT-50's auto-power-off timer is managed by a power-management circuit that can lose its state during a battery swap. After the swap, the timer may not re-initialise until the scale completes a full calibration cycle. Power the unit off manually, leave it off for 60 seconds, then power it back on — this forces the power-management circuit to re-read its stored settings and restores normal auto-off behaviour.
