It slots into the same bay as the original cell and restores the unit's ability to run sweeping and mopping cycles on hard floors. Voltage and capacity match the factory specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePlus 5200 and 5200C compatibility:\u003c\/strong\u003e\n    Both variants share the same battery bay geometry, voltage rail, and connector pinout. The 5200C added a mapping upgrade but kept the original 7.2V power architecture, so one cell fits both without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the cell through a full charge cycle and monitored BMS behaviour under the Mint's typical motor load. Voltage held steady through the sweep and mop phases with no cutoff events or anomalous heat at the contacts.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging discipline on the Mint Plus:\u003c\/strong\u003e\n    Do not leave the Mint sitting on its charging contacts indefinitely between uses. Continuous trickle charging on Ni-MH cells accelerates capacity fade faster than periodic full-cycle charging. Charge the unit fully, then remove it from the dock until the next cleaning session.\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 Mint Plus 5200\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells show a relatively flat discharge curve until capacity is nearly exhausted, then voltage drops quickly. The Mint's motor draws more current when the filter is even partially restricted, which accelerates that terminal voltage drop. A cell that still shows charge on the indicator can fall below the motor's minimum operating voltage under load if the filter is dirty. Clean the filter first — if suction recovers and holds, the cell is fine; if it still sags early, the cell has lost usable capacity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMint Plus 5200 motor cuts out mid-cycle then recovers after a pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a depleted cell. When the intake is blocked or the filter is clogged, the motor works harder and current draw spikes above the BMS threshold. The protection circuit opens, the unit stops, and after the BMS resets — typically within 30 to 60 seconds — it restarts. Clear the intake path, check the filter for debris buildup, and run again. If trips continue on a clean filter with a new cell, the motor itself is drawing above rated current and needs inspection.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428059938906,"sku":"BWCS-IRB380VX-1","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428059971674,"sku":"BWCS-IRB380VX-2","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428060004442,"sku":"BWCS-IRB380VX-3","price":44.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IRB380VX-1.webp?v=1779934037","url":"https:\/\/batteryweb.com\/products\/mint-plus-5200-replacement-battery-72v-1500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
