It powers the drive motors, brush roll, and onboard navigation electronics. No OEM part number is published by Coredy for this cell — the SKU CS-PCM720VX identifies it by fit model only.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eL900 \/ L900W \/ L900X platform fit:\u003c\/strong\u003e\n    All three variants share the same 14.4V battery bay, connector pinout, and BMS handshake protocol. The L900W and L900X are regional or spec revisions of the base L900 chassis — the battery draws, voltage rails, and physical slot are identical across all three.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and load discharge on the L900 platform. The BMS communicated correctly with the vacuum's control board, accepted charge from the standard dock, and did not trip overcurrent protection under normal carpet and hard floor suction loads.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit for the L900:\u003c\/strong\u003e\n    Do not leave the L900 sitting on the charging dock between uses indefinitely. Continuous trickle current from the dock accelerates capacity fade in Li-ion cells at this voltage class. Charge to full, then remove the vacuum from the dock until the next cleaning cycle.\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 L900\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe L900's BMS monitors cell voltage under load, not at rest. When the filter is partially blocked, the brush motor draws above its rated current to maintain suction. Voltage sags earlier under that elevated draw, and the BMS throttles output before the indicator registers a low-battery state. The result looks like a weak battery but is usually a restricted filter causing the motor to pull harder than the cell can sustain at full output. Clean or replace the filter first — if suction recovers to normal levels, the battery is not the fault.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eL900 motor cuts out mid-clean and then recovers after a short pause\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a battery failure. When suction is sustained against a blockage — tangled brush roll, clogged inlet, or a packed dustbin — current draw spikes past the cell's overcurrent threshold. The BMS disconnects output to protect the cell, then resets after the load clears. Clear the blockage, check that the dustbin is empty, and spin the brush roll by hand to confirm it moves freely. If the trip keeps happening with no blockage present, measure resting cell voltage: a healthy cell at full charge should sit at or above 16.4V open circuit.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427988701274,"sku":"BWCS-PCM720VX-1","price":62.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427988734042,"sku":"BWCS-PCM720VX-2","price":72.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427988766810,"sku":"BWCS-PCM720VX-3","price":80.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PCM720VX-1.webp?v=1779933755","url":"https:\/\/batteryweb.com\/products\/coredy-l900-replacement-battery-144v-6700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
