Tree LCT-Li-7 Electronic Scale Compatible Battery 7.4V 1100mAh

Tree LCT-Li-7 / LCT-Li-110 Series — 7.4V Li-Polymer Replacement Battery (LCT-Li-110-RB)

This 7.4V 1100mAh lithium-polymer battery replaces the original cell in Tree electronic scales, including the LCT-Li-7, LCT-Li-33, LCT-Li-110, and LCT-Li-16 series. It fits the OEM footprint at 52.20 × 40.00 × 10.20mm and matches the original connector layout. Swap it when the scale no longer holds charge or shuts down mid-weighing session.

• LCT-Li series compatibility: These Tree scales share a common 7.4V Li-Polymer cell format, the same BMS communication protocol, and an identical connector pinout across the LCT-Li-7, LCT-Li-33, LCT-Li-110, and LCT-Li-16 models. One cell fits all four.
• Bench tested on actual hardware: We cycled this cell through charge and load test on compatible scale hardware. The BMS accepted the new cell without triggering a protection fault, and voltage held steady under sustained load.
• Post-install warm-up on first power-on: After fitting the new battery, power the scale on and wait 30 seconds before placing any weight. The load cell amplifier needs to reach stable operating voltage before readings are accurate — this is normal behaviour, not a fault.

Error code on the display after battery swap

Tree scales store a zero-reference point in memory. When power is fully interrupted — which happens during a battery swap — that reference can reset or corrupt. The scale throws an error code because it no longer has a valid baseline to weigh against. Hold the tare button with nothing on the platform until the display returns to zero, then re-weigh. If the error persists, check that the battery voltage reads at least 7.2V at the terminals before assuming a scale fault.

Scale not switching off automatically after battery replacement

The auto-power-off timer on LCT-Li series scales is managed by the power-management circuit, which can lose its state during a hard battery disconnect. After the swap the timer may not trigger as expected. Power the scale fully off manually, leave it off for 60 seconds, then power it back on — this forces the circuit to re-read its power-management settings. If auto-off still does not engage, check the scale's menu for the auto-off timeout setting and re-enter the value.
