It fits the EDI 4 platform and supplies the sustained current the heating element draws during de-icing. Capacity is rated at 18.5Wh and matches the OEM specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEDI 4 platform fit:\u003c\/strong\u003e\n    The EDI 4 uses a fixed 7.4V two-cell Li-ion pack with a BMS that monitors cell voltage and temperature. This replacement matches that voltage rail and connector geometry, so the scraper's power management circuit recognises the pack and allows the heating element to activate.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through full charge and discharge cycles on the EDI 4. The BMS held cell balance across both cells throughout, and the heating element engaged without triggering overcurrent cutoff at startup.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-weather storage tip:\u003c\/strong\u003e\n    Store this battery indoors overnight before use. Below -10°C, internal cell resistance rises sharply, which limits how much current the pack can deliver to the heating element. A room-temperature battery performs significantly better than one left in the car overnight.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHeating element cutting out during use in extreme cold\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen ambient temperatures drop below -10°C, Li-ion cells lose usable capacity and internal resistance climbs. The heating element in the EDI 4 draws a sustained current load — at elevated cell resistance, voltage can sag far enough that the BMS interprets it as a low-cell event and cuts output to protect the cells. This is a protection trip, not a fault with the battery itself. Warming the battery to above 0°C before use brings internal resistance back down and allows the element to run through a full cycle without cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eEDI 4 not reaching scraping temperature even with a charged battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eIf the LED shows a full charge but the heating element feels weak or takes much longer than usual to warm up, the issue is usually a cell that has degraded below 3.5V per cell at rest. At that level, the pack reports full via the indicator circuit but cannot sustain the current the element needs under load. Check resting voltage with a multimeter — a healthy 7.4V two-cell pack should read between 7.4V and 8.4V when fully charged. If the reading is below 7.0V after a full charge cycle, the original battery has reached end of life and replacement is the correct fix.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377897275482,"sku":"BWCS-KRD400VX-1","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377897308250,"sku":"BWCS-KRD400VX-2","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377897341018,"sku":"BWCS-KRD400VX-3","price":52.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KRD400VX-1.webp?v=1778773919","url":"https:\/\/batteryweb.com\/products\/karcher-edi-4-replacement-battery-74v-2500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
