Capacity is 3000mAh (43.2Wh), matching the factory spec. It powers both the suction motor and the navigation system through the full cleaning cycle.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLASERBOT 650 and xBot 5 platform fit:\u003c\/strong\u003e\n    These four models share the same 14.4V battery bay, connector pinout, and BMS handshake protocol. One cell works across all four without any adapter or modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the LASERBOT 650 platform. The BMS negotiated correctly on first insertion — no reset needed, and the charge indicator reported accurately at each stage.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit for robotic vacuums:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock permanently between uses. Continuous trickle charging on Li-ion cells compresses the usable capacity over weeks. Charge to full, then lift it off the dock until the next run.\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\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe LASERBOT 650 motor draws significantly more current when the filter is partially blocked or the brush roll is tangled. That extra draw pulls the cell voltage down faster than the indicator circuit expects, so the vacuum loses suction while the display still shows a mid-range charge. The BMS interprets the voltage sag as a low-cell condition and reduces power to protect the cell. Clean the filter and check the brush roll before assuming the battery is the problem — a clear airpath brings current draw back within the rated window.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-cycle 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 intake, saturated filter, or hair wrapped tight on the brush — the motor stalls briefly and pulls a spike of current above the BMS threshold. The BMS shuts the output rail to protect the cell, then resets after a short thermal pause. The fix is to clear the restriction first. If cut-outs persist on a clean, unblocked vacuum, check that the replacement cell's BMS trip threshold matches the motor's rated draw at 14.4V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428007706714,"sku":"BWCS-CNS129VX-1","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428007739482,"sku":"BWCS-CNS129VX-2","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428007772250,"sku":"BWCS-CNS129VX-3","price":60.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CNS129VX-1.webp?v=1779933824","url":"https:\/\/batteryweb.com\/products\/symbo-laserbot-650-replacement-battery-144v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
