It slots into the same battery bay and connects to the same BMS handshake as the factory unit. Capacity is 10000mAh (185Wh), matching the OEM specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXR5 4000 and XR5 3000 platform fit:\u003c\/strong\u003e\n    Both models share the same 18.5V battery architecture, connector pinout, and BMS communication protocol — which is why one pack covers both. Part numbers 753-11261, 725-17288, 753-11259, 753-11258, and 725-18095 are all cross-referenced to this voltage rail.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through simulated blade-motor inrush loads. The BMS held the connection through the high-current draw at startup and did not trip under sustained mid-range cutting loads.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSeasonal storage tip:\u003c\/strong\u003e\n    If your mower sits in an unheated garage through winter, bring the battery indoors the night before your first spring cut. Li-ion cells below 10°C carry higher internal resistance, and the blade motor's inrush current on a cold pack can trip the BMS before the mower even moves.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff under thick or wet grass blade load\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the XR5 hits dense or wet turf, the blade motor pulls a spike of current well above its steady-state draw. If the pack's cells are partially discharged or warm from prior use, the BMS can read that spike as an over-current fault and disconnect the output rail. The mower stops, then resets after a short pause. Keeping the pack above 30% charge before tackling heavy patches significantly reduces the frequency of these trips — the BMS threshold is tighter at lower state of charge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger won't accept the pack after winter storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA battery left unused over winter can self-discharge below the charger's acceptance threshold — typically around 10–12V per cell group on an 18.5V pack. When the charger sees voltage that low, it reads the pack as faulty and refuses to start a charge cycle. The fix is a slow trickle-recovery charge if your charger supports it, or leaving the pack on the charger for up to 30 minutes — some units will eventually attempt a recovery pulse once the connection stabilises. If the charger still shows a fault light after 30 minutes, check cell voltage across the pack terminals; below 14V total usually means one or more cells have dropped into an unrecoverable range.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381288829018,"sku":"BWCS-RRK400VX-1","price":231.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381288861786,"sku":"BWCS-RRK400VX-2","price":275.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381288894554,"sku":"BWCS-RRK400VX-3","price":308.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RRK400VX-1.webp?v=1778899919","url":"https:\/\/batteryweb.com\/products\/cubcadet-xr5-4000-replacement-battery-185v-10000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
