It fits the handheld unit used for spot-cleaning pet stains and odours from carpet and upholstery. Capacity is 19.24Wh — matched exactly to the product data, not estimated from third-party sources.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePet Stain Eraser 20037 fit:\u003c\/strong\u003e\n    The 20037 uses a compact 7.4V two-cell Li-ion pack with a specific BMS handshake. This replacement matches that voltage rail and connector format so the charger recognises the pack and completes the charge cycle normally.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the 20037 platform. The BMS engaged correctly at low-voltage cutoff, the charger handshake completed without fault codes, and the motor drew current within rated parameters throughout the test.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging on the 20037:\u003c\/strong\u003e\n    Do not leave the 20037 sitting on its charging base permanently. The unit trickle-charges when docked and the cell is already full — this degrades capacity faster than normal use cycles. Charge to full, then remove it from the dock.\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 20037 motor draws more current when airflow is restricted — a partially blocked filter forces the motor to work harder than rated. This extra draw causes voltage to sag across the cell before the indicator registers a low charge state. The result is noticeably weaker suction while the LED still shows adequate battery. Clean or replace the filter first — if suction recovers, the battery is not the problem.\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 — blocked nozzle, clogged filter, hair wrap on the brush — the motor pulls current above the BMS trip threshold and the pack shuts output to protect the cells. The BMS resets after a short thermal recovery window, which is why the unit starts again after a pause. Clear the blockage before the next run and check the filter is seated correctly — a loose filter seal bypasses the airflow path and triggers the same trip at 7.4V operating voltage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426407776346,"sku":"BWCS-BSE237VX-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426407809114,"sku":"BWCS-BSE237VX-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426407841882,"sku":"BWCS-BSE237VX-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BSE237VX-1.webp?v=1779933098","url":"https:\/\/batteryweb.com\/products\/bissell-pet-stain-eraser-20037-replacement-battery-74v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
