It fits directly into the FC6152\/81 and restores power to the motor when the original cell has degraded. Capacity figures come from the product data — 2000mAh at 7.2Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFC6152\/81 cell match:\u003c\/strong\u003e\n    The FC6152\/81 runs a single 3.6V Ni-MH cell at a low voltage rail suited to a compact handheld motor. Staying within that voltage band keeps the motor controller operating as the unit expects — no over-voltage stress on the drive circuit.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through repeated charge and discharge passes on the FC6152\/81 platform. The BMS accepted the cell without fault codes, and suction remained consistent across the test cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging on the FC6152\/81:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock continuously. Ni-MH cells in handheld vacuums develop capacity fade faster under constant trickle charge than cells charged only when depleted. Charge to full, then remove the unit from the dock.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery fade from leaving the FC6152\/81 on continuous dock charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells do not tolerate indefinite trickle charging well. The FC6152\/81 dock delivers a maintenance charge once full, but over weeks that low-level current breaks down the cell chemistry and reduces usable capacity. The symptom is a vacuum that runs for noticeably less time per charge cycle than it did when new. Charge the unit only when depleted, remove it from the dock once full, and repeat — this single habit extends cell life significantly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSuction dropping off before the low-battery indicator activates\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA partially blocked filter forces the FC6152\/81 motor to draw more current than rated to maintain airflow — this pulls the cell voltage down faster than the indicator circuit expects. The result is noticeable suction loss while the indicator still shows charge remaining. This is not a faulty battery. Check and clear the filter first, then retest. If suction holds steady after a clean filter, the cell voltage sag was load-driven, not a capacity problem.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427981492314,"sku":"BWCS-AER393VX-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427981525082,"sku":"BWCS-AER393VX-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427981557850,"sku":"BWCS-AER393VX-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AER393VX-1.webp?v=1779933648","url":"https:\/\/batteryweb.com\/products\/philips-fc615281-replacement-battery-36v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
