PROBAT PRO CONTROL Remote Replacement Battery 3.7V 1200mAh

PROBAT PRO CONTROL — 3.7V Li-ion Replacement Battery

This is a 3.7V, 1200mAh Li-ion replacement battery for the PROBAT PRO CONTROL wireless remote. The PRO CONTROL remote is used to adjust roasting parameters and monitor process data on PROBAT industrial coffee roasting equipment from a distance. When the original cell depletes, this replacement restores full remote operation.

• PRO CONTROL remote fit: The PRO CONTROL uses a slim 3.7V Li-ion cell — 53.00 x 33.90 x 5.70mm — to power its IR transmission and onboard logic. This replacement matches that form factor and voltage rail directly. No modification needed.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a Li-ion test rig. The protection circuit handled overvoltage and over-discharge cutoff correctly, and IR output stayed consistent across the discharge curve.
• Single-cell remote swap tip: The PRO CONTROL runs one Li-ion cell, not an alkaline pair — but polarity still matters. The connector orientation on Li-ion pouch cells is not always obvious. Confirm the positive terminal aligns with the marked polarity on the battery bay before closing the housing.

Why the PRO CONTROL stops responding mid-roast session

The PRO CONTROL's IR LED needs a minimum voltage to fire a signal strong enough for the receiver on the roaster to register. As a Li-ion cell ages, its resting voltage drops gradually — but the usable threshold for reliable IR transmission is reached well before the cell reads zero. A cell showing 3.5V on a multimeter can still cause missed commands because the current draw during IR pulse transmission pulls the voltage below the LED's operating floor momentarily. Replacing the cell is the fix, not repositioning the remote.

PRO CONTROL remote dead immediately after battery install

If the remote shows no response at all right after fitting a new cell, the first thing to check is polarity. Li-ion pouch cells use a JST-style connector or direct contact pads, and the positive and negative orientation is easy to reverse — especially if the original cell was removed without noting its position. A reversed cell does not charge and will not power the remote. Reseat the battery with the positive terminal correctly aligned; the remote should power on immediately.
