About this replacement
Samsung BN59-01357F Series — 3.85V Li-Polymer Replacement Battery (BN59-01357A)
This is a 3.85V, 210mAh Li-Polymer battery that replaces the original rechargeable cell in Samsung solar and USB-rechargeable TV remotes. It fits the BN59-01357F, BN59-01385A, and over 90 compatible Samsung TV remote models including GQ43Q72AAUXZG and GQ43Q73AAUXZG variants. The OEM part numbers are BN59-01357A and BP59-00150A.
- Why these remotes share this battery: Samsung's solar and USB-C rechargeable remote lineup uses a standardised 3.85V Li-Polymer cell across multiple TV generations. The shared connector footprint and BMS voltage threshold mean one cell covers the full BN59-013xx family without modification.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a BN59-01357F unit. The BMS accepted the charge curve cleanly, IR output held consistent across the full state of charge, and no protection trips were logged during normal use.
- Li-Polymer cell handling for slim remotes: These flat pouch cells are pressure-sensitive. Do not bend or crease the cell body during installation — even minor deformation can compromise the internal layers and cause premature capacity loss.
Why your Samsung remote stops working right after a battery swap
The most common cause is reversed polarity. The positive terminal on this Li-Polymer cell is marked, but the contact orientation inside the remote housing differs by model — some are flipped relative to what you'd expect. If the remote shows no response immediately after install, flip the cell 180 degrees and re-seat it. A correctly installed cell at 3.85V will bring the remote back online instantly with no pairing required.
Remote suddenly needs to point directly at the TV to register button presses
This symptom means the battery voltage has dropped below the threshold the IR LED needs to fire at full power. At reduced voltage, the LED still pulses but the signal is too weak to reach the TV sensor at normal angles. It is not a remote fault — it is a low-cell indicator. Replace the battery and confirm the new cell reads 3.85V before installation.
