It fits directly into the PCR-1550M handset and restores power to the motor and suction system. Capacity is rated at 25.92Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePCR-1550M motor compatibility:\u003c\/strong\u003e\n    The PCR-1550M runs a brushed DC motor on a 14.4V rail. Ni-MH chemistry at this voltage handles the sustained draw of vacuum operation without the BMS trip sensitivity you get in Li-ion packs — the motor can pull hard during carpet passes without cutting out.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full discharge and recharge sequences, monitoring cell voltage balance and BMS response under load. The pack held voltage above the motor's cutoff threshold through sustained draw and recovered cleanly between cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging on the PCR-1550M:\u003c\/strong\u003e\n    Do not leave the vacuum on the charging dock continuously. Ni-MH cells in cordless vacuums develop capacity fade faster under constant trickle charge than under normal use cycles. Charge to full, then remove the unit from the dock until the next use.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSuction dropping before the battery indicator reaches low on the PCR-1550M\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when Ni-MH cells age and internal resistance rises. The motor still runs, but voltage sags under load before the pack is genuinely depleted — the indicator reads mid-range while suction is already weak. A blocked or dirty filter makes this worse because the motor works harder and draws more current, accelerating the voltage sag. If suction recovers after cleaning the filter, the battery still has usable capacity. If suction stays weak with a clean filter, cell degradation is the cause and a replacement pack is the fix.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean and then recovers after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When suction is restricted — blocked filter, clogged inlet, or dense carpet pile — the motor draws more current than the BMS allows and the pack disconnects briefly to protect the cells. The recovery happens once current demand drops and the BMS resets. Check the filter and clear any blockage at the inlet first. If the cutout continues on a clean, unblocked machine, check that the replacement pack's BMS current threshold matches what the PCR-1550M motor expects.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428058497114,"sku":"BWCS-DML608VX-1","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428058529882,"sku":"BWCS-DML608VX-2","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428058562650,"sku":"BWCS-DML608VX-3","price":70.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DML608VX-1.webp?v=1779934014","url":"https:\/\/batteryweb.com\/products\/sichler-pcr-1550m-replacement-battery-144v-1800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
