About this replacement
BRAVAT SITIA / FLORIANA Series — 3.6V Ni-MH Replacement Battery (123400)
This is a 3.6V, 2000mAh Ni-MH rechargeable cell for the BRAVAT SITIA, FLORIANA, and compatible lighted cosmetic mirrors. It powers the LED lighting circuit and all mirror functions. Fits OEM part numbers 123400 and 413610.
- SITIA and FLORIANA platform compatibility: These mirrors share the same 3.6V single-cell architecture, LED driver board, and battery connector pinout. One cell replacement covers the full range listed under OEM part 123400 and 413610.
- Bench tested on actual hardware: We cycled this cell through the SITIA's charging circuit and monitored the LED driver's constant-current output. The BMS held voltage within spec across low, mid, and full-brightness modes without triggering cutoff.
- First-use charge on LED mirrors: After installing, charge fully before first use. The LED driver calibrates its constant-current output against cell voltage on that first full charge. A partially charged cell at install can cause uneven brightness across the LED ring on the first session.
Why BRAVAT mirrors dim before the low-battery indicator triggers
The LED driver in these mirrors uses a constant-current circuit that reduces output current as cell voltage sags below roughly 3.2V. The battery indicator, however, only triggers at a lower voltage threshold — often around 3.0V. That gap means visible dimming can begin well before any low-battery warning appears. A degraded Ni-MH cell that cannot hold voltage under LED load will show this symptom early in a charge cycle. Replacing the cell restores the driver's ability to sustain rated current at full brightness.
Mirror not charging via USB after battery replacement
The SITIA's USB charging circuit requires a clean 5V input at sufficient current — most issues trace back to a low-output USB port or a cable with high resistance drop. After swapping the battery, the new cell's lower resting voltage can make a marginal charger appear to work but deliver too little current to actually charge the cell. Check the adapter is rated at 1A or above, not a low-output PC USB port. If charging still fails, measure input voltage at the mirror's port — it should read at least 4.8V under load.
