Fits Braun Micron Vario 5564 and replaces OEM part number 180AAH.
1.2V, 1800mAh Ni-MH cell delivers consistent voltage to the motor throughout the charge cycle without the voltage sag that causes mid-shave slowdown.
Cylindrical AA form factor; slides into the battery compartment with flat contacts aligned to the shaver's spring terminals.
We bench-tested this cell in the Micron Vario 5564 charging dock; the BMS accepted the charge profile on first insertion with no fault codes.
On first use after installation, run a full charge-to-empty cycle before relying on the low-battery indicator — Ni-MH cells need one discharge pass for the device firmware to calibrate capacity correctly.

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Braun Micron Vario 5564 / Syncro / Activator — 1.2V Ni-MH Replacement Battery (180AAH)

This is a 1.2V 1800mAh Ni-MH cell that replaces the OEM 180AAH battery in Braun cordless shavers. It fits the Micron Vario 5564, Flex Integral, Syncro, and Activator series, along with over 200 additional compatible models. Voltage and capacity match the original spec exactly.

  • Broad model compatibility: These shavers share a common 1.2V single-cell Ni-MH architecture with the same physical form factor — 49.90 × 14.30 × 14.30mm — and the same charging circuit handshake. One cell swap covers the full platform.
  • Bench tested on actual hardware: We cycled this cell through the Syncro charging dock and monitored BMS response at full charge termination. The delta-V cutoff triggered cleanly at the expected charge ceiling with no overcharge event observed.
  • Dry the charging contacts before docking: These shavers are rinsed under the tap. Water left on the charging port bridges the contacts and trips a BMS protection fault. The shaver reports a dead battery — but the fault is moisture, not the cell. Dry the port thoroughly before connecting to the charger.

Capacity fade from daily partial charging on the Braun Syncro and Activator

Ni-MH cells in shavers degrade faster when charged daily before the cell is close to depleted. Each shallow cycle adds to voltage depression — a condition where the cell accepts a full charge but delivers less usable voltage under motor load. The charge indicator reads full, but the shaver cuts out earlier each week. Replacing the cell resets this, but running the new cell through two or three full discharge-charge cycles after fitting helps the BMS recalibrate its state-of-charge tracking.

Motor speed dropping before the low-battery indicator activates

Under the load spike when the shaver motor starts, the cell voltage sags below the motor's minimum operating threshold before the BMS registers a low-battery condition. This is a voltage-sag failure, not a capacity failure — the cell still holds charge but can't sustain the current draw. Users notice the cutting head slowing or stalling mid-shave while the indicator still shows charge remaining. If the resting voltage measures above 1.1V after the shaver cuts out, replace the cell — the BMS trip threshold is set around 1.0V under load.

Frequently Asked Questions

My Braun shaver slows down mid-shave but the battery indicator still shows charge — what's happening?

This is voltage sag under motor load. The cell still holds charge at rest, but when the motor draws current, the cell voltage drops below the motor's operating threshold before the BMS flags it as low. It's a sign the cell can no longer sustain the current demand — not that the indicator is broken. Check resting voltage after it cuts out: if it reads above 1.0V, the cell needs replacing.

The shaver stopped charging after I rinsed it — dock light comes on but the battery never fills up

Water left on the charging port bridges the contacts and triggers a BMS protection fault. The dock light activates because the dock is live, but the BMS has cut off the charge path to protect the cell. Disconnect the shaver, dry the charging port completely with a cloth or compressed air, and leave it for 30 minutes before docking again. If it still won't charge after that, the cell itself may need replacing.

I put a new battery in and the shaver works, but it seems to run out faster than it should — did I get a dud cell?

Probably not. A fresh Ni-MH cell often needs two or three full discharge-charge cycles before the BMS accurately tracks its capacity. If the shaver was previously run on a degraded cell, the BMS charge counter may still be calibrated to the old cell's lower baseline. Run the shaver until it cuts out completely, then charge it to full — repeat this twice more and the indicator should align with the actual cell capacity.
