These scales are used in laboratories, pharmacies, and retail counters where battery failure means downtime and lost weighing capacity. Swap this unit in and the scale returns to full operation without any firmware changes.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePES and PEJ platform compatibility:\u003c\/strong\u003e\n    Both series share the same 7.2V power rail, connector housing, and BMS handshake protocol — one battery cell pack covers the entire range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a KERN PES unit. The BMS accepted the charge profile on the first attempt, voltage held steady at 7.2V under load, and the scale's internal calibration flag did not trigger.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eZero-point reset after installation:\u003c\/strong\u003e\n    KERN PES\/PEJ scales store their zero reference in volatile memory. After fitting a new battery, remove all weight from the pan and hold the Tare button for three seconds before your first measurement — skipping this step can produce a fixed offset error across all readings.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWeighing accuracy drift in the first 30 seconds after power-on\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eKERN PES\/PEJ scales use a load cell amplifier that requires a stable supply voltage before it locks onto its reference point. When a fresh or recently fitted battery first powers the unit, the cell voltage climbs from resting state toward its operating level. During this climb the amplifier has not yet settled, so displayed readings can drift by several digits. Wait a full 30 seconds after power-on with nothing on the pan before placing any sample — the amplifier stabilises once supply voltage holds at 7.2V.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScale not switching off automatically after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe auto-off timer on PES\/PEJ models is managed by the power-management circuit, which references a counter stored in low-power RAM. A hard power loss — such as a flat battery removed mid-session — can corrupt that counter, leaving the scale running indefinitely after the new battery goes in. To reset it, power the scale on, enter the setup menu (hold the Mode button for five seconds), and navigate to the power-off timer setting. Confirm the value and save — this rewrites the counter and restores normal auto-off behaviour.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360293519450,"sku":"BWCS-KRS100SL-1","price":71.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43360293552218,"sku":"BWCS-KRS100SL-2","price":83.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43360293584986,"sku":"BWCS-KRS100SL-3","price":92.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KRS100SL-1.webp?v=1778611049","url":"https:\/\/batteryweb.com\/products\/kern-kern-pespej-replacement-battery-72v-4500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
