It slots into the battery compartment directly and restores power to the drive motors and navigation system. Capacity is 2800mAh (40.32Wh), matching the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCleanmate and Veluce R290 fit:\u003c\/strong\u003e\n    Both models run the same 14.4V battery platform with an identical connector layout and BMS communication protocol. A single replacement cell 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 passes on the Cleanmate platform. The BMS accepted the handshake cleanly — no false low-battery cutoffs and no thermal shutdowns during sustained motor draw on hard floor and carpet transitions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging practice for Ni-MH cells:\u003c\/strong\u003e\n    Ni-MH chemistry in robotic vacuums is particularly sensitive to continuous dock charging. Leaving the unit on the dock permanently triggers a slow trickle charge that degrades cell capacity faster than normal use cycles. Charge to full, then remove the unit from the dock until the next clean is needed.\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 Cleanmate's motor draws significantly more current when the filter is partially blocked or the intake path is restricted. Under that extra load, the battery voltage sags earlier than the indicator circuit expects, so the vacuum loses suction while the gauge still shows a mid-level charge. The BMS reads the voltage sag as a near-depleted cell and reduces power delivery to protect the pack. Clean the filter and clear the intake before assuming the battery is the fault — a restricted motor pulling above rated current will drain even a new cell faster than the indicator tracks.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eReplacement battery not charging on the dock\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome Klarstein charger units expect a specific voltage response from the battery during the initial charge handshake. If the replacement cell sits at a lower resting voltage after shipping and storage, the charger may not trigger its charge cycle. Remove the battery, let it sit at room temperature for 30 minutes, then reseat it on the dock. If the charge indicator still does not activate, confirm the dock output is at the rated 16–17V DC using a multimeter before concluding the battery is at fault.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428089004122,"sku":"BWCS-IRB530VX-1","price":73.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428089036890,"sku":"BWCS-IRB530VX-2","price":85.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428089069658,"sku":"BWCS-IRB530VX-3","price":94.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IRB530VX-1.webp?v=1779934037","url":"https:\/\/batteryweb.com\/products\/klarstein-cleanmate-replacement-battery-144v-2800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
