Flushmatic 2CR123A Replacement Battery 6V 1350mAh

Flushing system Flushmatic / Hydrocell / Aquamate — 6V Li-MnO2 Replacement Battery (2CR123A / CRP2MFISH)

This is a 6V, 1350mAh lithium manganese dioxide battery for automatic sensor flush valves. It fits Flushing system Flushmatic, Hydrocell, Aquamate, and Gentworks units, along with two additional compatible models. The battery powers both the passive infrared motion sensor and the solenoid valve that triggers each flush cycle.

• Flushmatic, Hydrocell, Aquamate, Gentworks compatibility: These units share the same 6V sensor-and-solenoid architecture, 2CR123A cell format, and BMS handshake threshold. One battery spec covers all of them because the solenoid activation voltage and connector format are identical across the range.
• Bench tested on actual hardware: We ran this cell through repeated solenoid actuation cycles on a Flushmatic unit. The BMS held voltage above the 5.4V solenoid minimum across extended cycling, and the sensor circuit maintained consistent detection range throughout.
• Post-install sensor reset: After fitting this battery, wave a hand slowly in front of the sensor three times. This triggers the unit's self-test flush sequence, confirms the new cell is accepted, and verifies the sensor is reading correctly before the cubicle goes back into service.

Flusher activating randomly after new battery installed

Random or phantom flushes after a battery swap are almost always caused by skipping the power-cycle reset. The sensor PIR circuit retains its previous detection baseline from the old cell and misreads residual heat signatures as motion. Pull the battery, wait 30 seconds, then reinsert it. This forces the sensor to recalibrate its detection threshold from zero with the new cell voltage.

Battery draining faster than expected in high-traffic washrooms

Each solenoid actuation draws a short high-current pulse — typically 1–2A for 200–400ms. In a cubicle with 80 or more flushes per day, that cycle count compounds quickly against total cell capacity. Li-MnO2 chemistry handles these pulse loads better than alkaline, but capacity still depletes faster in high-traffic installations than manufacturer estimates suggest. If a cubicle is seeing unusually short battery life, check whether the sensor dwell time or flush interval is set to the shortest available value in the unit's adjustment menu — reducing unnecessary activations directly extends battery life.
