Savant Pro REM-1000 Replacement Battery 3.7V 2200mAh

Savant Pro REM-1000 Touchscreen Remote Control — 3.7V Li-Polymer Replacement Battery (AHA1112200)

This 3.7V, 2200mAh Li-Polymer battery replaces the OEM AHA1112200 cell in the Savant Pro REM-1000 touchscreen remote. The REM-1000 is a home automation and entertainment controller — it handles IR, RF, and touchscreen input simultaneously, which puts steady load on this single cell. Dimensions are 66.40 x 33.00 x 10.30mm; confirm these against your original before installing.

• REM-1000 compatibility: The REM-1000 runs its touchscreen digitizer, backlight, and IR blaster from this single Li-Polymer cell. All three share the same voltage rail, so when the cell drops below threshold, the touchscreen stutters before the IR output fails — not a firmware issue, a voltage issue.
• Bench tested on actual hardware: We cycled this cell through full charge and simulated home-automation loads — backlight on, repeated IR burst sequences. The BMS held voltage within spec across the discharge curve and triggered protection cutoff cleanly at the low-voltage limit with no lockout requiring a hard reset.
• Touchscreen calibration after swap: After fitting a new cell, the REM-1000 may prompt a touchscreen recalibration. Complete it before docking the remote — skipping it leaves the digitizer offset and tap targets will register incorrectly until calibration runs.

Why the REM-1000 touchscreen goes unresponsive before the remote stops transmitting

The REM-1000's touchscreen digitizer draws power continuously to maintain touch sensitivity, even in standby. As the cell ages and internal resistance climbs, the digitizer loses stable voltage first — the IR blaster can still fire short bursts on a weaker cell because each transmission is brief. This means users often report an unresponsive screen while the remote still seems to "work" when they press physical shortcuts. Replacing the cell resolves this; don't chase a firmware or screen fault until the battery is confirmed healthy.

REM-1000 shows charging indicator but battery percentage stays stuck

A stuck charge percentage on the REM-1000 is almost always a fuel-gauge calibration issue, not a faulty replacement cell. The onboard fuel gauge loses accuracy when a deeply discharged original cell is swapped out — the new cell's actual state of charge doesn't match the gauge's stored reference. Run the new cell down until the remote shuts off, then charge it uninterrupted to 100% without using the remote mid-cycle. This resets the gauge reference and the percentage will track correctly from that point forward.
