It matches the original voltage rail and connector, so the charger and motor controller recognise it without modification. Capacity is 3400mAh (48.96Wh), identical to the factory specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e2142 and 1605C platform fit:\u003c\/strong\u003e\n    These models share the same 14.4V battery bay, connector pinout, and BMS handshake protocol. A single pack covers all listed variants because the motor controller reads the same voltage and cell configuration across the range.\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 the 2142 platform. The BMS accepted the charger handshake on first connection, and the cell protection circuit tripped correctly at the rated low-voltage cutoff without triggering false shutdowns under normal suction load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging behaviour on the 2142:\u003c\/strong\u003e\n    Remove the vacuum from the charging dock once the indicator shows full. Bissell's dock design passes a low-level trickle current continuously — leaving the pack on dock between uses accelerates capacity fade on lithium cells faster than on-demand charging cycles do.\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 motor in the 2142 draws significantly more current when the filter is partially blocked or the dustbin is near capacity. That elevated draw causes the cell voltage to sag under load, which the BMS interprets as a low-charge condition — cutting motor speed before the indicator changes. The battery itself is not depleted; the pack voltage recovers as soon as load drops. Clean the filter and empty the bin, then retest — if suction holds at full speed, the pack is delivering correctly at 14.4V nominal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean then restarts after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a failed battery. When sustained suction restriction — blocked filter, tangled brush roll, or sealed pickup nozzle — forces the motor to draw above the pack's rated discharge current, the BMS opens the circuit to protect the cells. It resets automatically once current demand falls and cell temperature drops. The fix is to clear the restriction first: check the filter, brush roll, and hose before assuming the battery is at fault. If trips continue on an unobstructed machine, measure resting pack voltage — it should read between 15.6V and 16.8V after a full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428023369818,"sku":"BWCS-PHC882VX-1","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428023402586,"sku":"BWCS-PHC882VX-2","price":60.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428023435354,"sku":"BWCS-PHC882VX-3","price":66.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PHC882VX-1.webp?v=1779933917","url":"https:\/\/batteryweb.com\/products\/bissell-2142-replacement-battery-144v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
