It fits the MPS, MBB, MTS, and MCB series, along with two additional compatible models. It directly replaces OEM part numbers FOB-A08 and FOB-A07.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMPS, MBB, MTS, and MCB platform compatibility:\u003c\/strong\u003e\n    These KERN scale series share the same 7.2V battery rail, connector pinout, and BMS handshake protocol. That common architecture means one cell pack covers the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on a KERN MPS unit. The BMS accepted the cell chemistry without fault codes, held voltage within the expected 7.2V operating band, and completed a full charge cycle cleanly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eLoad cell warm-up after swap:\u003c\/strong\u003e\n    After fitting this battery and powering on, wait 30 seconds before placing any weight on the platform. The load cell amplifier needs to stabilise at operating voltage first — weighing before that window can produce readings that are slightly off.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy KERN scales show an E code after a battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAn E or error code immediately after a battery swap is almost always a zero-point calibration fault, not a hardware failure. When power is cut and restored, the scale's internal reference loses its last tare zero. The fix is straightforward: place the empty pan on the scale and hold the Tare button for three to five seconds until the display resets to 0.000. If the error persists past that step, check that the battery is seated fully and the connector is locked — a loose contact causes voltage dips that trigger the same code.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScale draining the new battery faster than the original\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eBacklit displays and any active wireless data transmission draw significantly more current than a basic numeric display. If your KERN unit has both features active simultaneously, the draw is higher than most users expect from a scale. Check the settings menu and disable wireless transmission when it is not needed — this is the single biggest drain reduction available. For storage between uses, power the scale off completely rather than relying on auto-shutoff, as the power-management circuit on some units continues a small background draw in standby.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360294207578,"sku":"BWCS-KRM800SL-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360294240346,"sku":"BWCS-KRM800SL-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360294273114,"sku":"BWCS-KRM800SL-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KRM800SL-1.webp?v=1778611048","url":"https:\/\/batteryweb.com\/products\/kern-mps-replacement-battery-72v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
