It fits the M607 Spider, M607 Spider wie, M612 Spider wie, and Fusion, among others. Voltage and cell count match the original pack exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSpider series compatibility:\u003c\/strong\u003e\n    These models share the same 14.4V battery platform, connector layout, and BMS communication protocol. Swapping packs across M607 and M612 variants works because the motor driver and charge circuit expect the same voltage rail.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on a M607 Spider unit. The BMS held cutoff correctly at low cell voltage and accepted a full charge without thermal event or cell imbalance flag.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit for Spider vacuums:\u003c\/strong\u003e\n    Do not leave the M607 sitting on the dock permanently between uses. Continuous trickle charging accelerates capacity fade in Ni-MH cells faster than in lithium packs. Charge fully, then remove 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\"\u003eCordless vacuum losing suction before the battery indicator reaches low\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eOn the M607 Spider, suction can drop noticeably while the battery indicator still shows charge remaining. This happens because a partially blocked filter forces the motor to draw more current than rated, causing voltage to sag under load before the cell is actually depleted. The BMS reads the voltage dip as low battery and throttles output to protect the cells. Clean or replace the filter first — if suction recovers, the battery is not the fault.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean 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 — by a blocked filter, a tangled brush roll, or a sealed nozzle — the motor draws a sustained current spike that exceeds the BMS threshold. The pack disconnects the output rail to protect the cells, then resets once current demand drops. Clear the restriction, wait ten seconds, and power the vacuum back on. If the trip repeats immediately on an unblocked machine, cell voltage under load has likely dropped below 1.0V per cell and the pack needs replacing.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428058300506,"sku":"BWCS-DML608VX-1","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428058333274,"sku":"BWCS-DML608VX-2","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428058366042,"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\/dirt-devil-m607-spider-replacement-battery-144v-1800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
