It slots into the original battery compartment and restores power to the motor drive circuit. Capacity is 2000mAh (28.8Wh), matching the stock specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eM-288 and M-488 platform fit:\u003c\/strong\u003e\n    Both models share the same 14.4V motor rail, battery form factor, and connector orientation. A single cell spec covers both units without modification.\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 discharge on the M-288 motor circuit. The BMS held voltage within spec under sustained suction load and triggered no false overcurrent cutoffs on clean filters.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging practice for this vacuum:\u003c\/strong\u003e\n    Do not leave the M-288 sitting on the charging dock after the cell reaches full charge. Ni-MH cells in cordless vacuums develop capacity fade noticeably faster under continuous trickle charge. Charge to full, then remove 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\n  \u003cp class=\"bpw-desc-p\"\u003eThe M-288 motor draws higher current the moment airflow is restricted — a partially blocked filter forces the motor to work harder, pulling the cell voltage down faster than the indicator circuit registers. The result is a noticeable suction drop while the LED still shows adequate charge. This is not a cell defect. Clean or replace the filter first, then retest. If suction recovers immediately after filter service, the battery is fine.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-use then recovering after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a loose connection. When the vacuum runs sustained suction against a blockage or heavily loaded carpet, current draw spikes past the BMS threshold and the circuit opens to protect the cell. The BMS resets automatically once current drops, which is why the motor restarts seconds later. Clear any blockage, check the filter is seated correctly, and verify the cell is above 12.5V resting before the next run.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428088414298,"sku":"BWCS-IRB400VX-1","price":82.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428088447066,"sku":"BWCS-IRB400VX-2","price":96.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428088479834,"sku":"BWCS-IRB400VX-3","price":107.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IRB400VX-1.webp?v=1779934037","url":"https:\/\/batteryweb.com\/products\/klarstein-m-288-replacement-battery-144v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
