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.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBroad model compatibility:\u003c\/strong\u003e\n    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.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    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.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDry the charging contacts before docking:\u003c\/strong\u003e\n    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.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCapacity fade from daily partial charging on the Braun Syncro and Activator\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-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.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor speed dropping before the low-battery indicator activates\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eUnder 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.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416125636698,"sku":"BWCS-MCH180SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416125669466,"sku":"BWCS-MCH180SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416125702234,"sku":"BWCS-MCH180SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MCH180SL-1.webp?v=1779760313","url":"https:\/\/batteryweb.com\/products\/braun-micron-vario-5564-replacement-battery-12v-1800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
