LeTV RC60Tp6 Remote Compatible Battery 3.7V 1200mAh Li-ion

LeTV RC60Tp6 / S40 / S50 / SRC Series — 3.7V Li-ion 1200mAh Replacement Battery

This is a 3.7V, 1200mAh Li-ion replacement battery for the LeTV RC60Tp6 remote and compatible models including the S40, S50, and SRC series. It restores full IR output to LeTV television remotes that have lost range or stopped responding entirely. Dimensions are 53.00 × 33.90 × 5.70mm — measure your existing cell before ordering.

• RC60Tp6 and S-series compatibility: These remotes share the same flat Li-ion cell format, voltage rail, and connector footprint. A single cell spec covers the RC60Tp6, S40, S50, and SRC without any modification.
• Bench tested on actual hardware: We ran this cell through charge cycles on RC60Tp6 hardware and confirmed the BMS held a stable 3.7V nominal output without voltage sag during IR burst transmission.
• Single-cell remote swap rule: This remote runs on one cell — not two. There is no old-cell compensation issue here, but do not pair this new cell with a partially depleted spare if your remote uses an extended grip with a secondary cell slot. Replace the full cell.

Why the RC60Tp6 stops working after a new battery is installed

The most common cause is polarity reversal. The RC60Tp6 battery compartment has a snug fit, and the positive and negative contacts are easy to misread under low light. Installing the cell backwards delivers no voltage to the IR circuit, so the remote appears completely dead. Check the embossed + and − markings on the battery against the contacts in the tray. Re-seat the cell in the correct orientation and the remote should respond immediately.

Remote range dropping before the battery is fully depleted

IR LEDs in the RC60Tp6 need a sustained voltage above roughly 3.5V to fire at full strength. As a Li-ion cell ages past 80% of its cycle life, resting voltage stays nominally acceptable but sags under the brief high-current burst the IR LED demands. The result is reduced range — the remote only works at close distance — before any low-battery indicator appears. If you are pointing the remote within 0.5m to get a response, the cell is below its usable IR output threshold and needs replacement.
