It matches the OEM voltage and form factor, fitting the internal battery bay without modification. Capacity is 2100mAh (12.6Wh), identical to the factory specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEW-N\/EG-N platform compatibility:\u003c\/strong\u003e\n    These models share the same internal voltage rail, connector pinout, and battery bay dimensions. All four variants accept the GPRHC21HN036 cell pack without adaptation — the BMS handshake is consistent across the range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and discharge on EG-N hardware. The BMS accepted the cell pack without fault codes, held the 6V rail steady under load, and passed zero-point calibration after each cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install warm-up on the EW-N\/EG-N:\u003c\/strong\u003e\n    After fitting this battery, power the scale on and wait 30 seconds before placing any load. The load cell amplifier in these scales requires time to stabilise at operating voltage — weighing immediately after cold power-on produces readings outside the stated accuracy specification.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eError code on the EG-N display after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eKERN EG-N scales store their zero-reference in volatile memory. When power is interrupted — including during a battery change — that reference is lost. The scale throws an error or E code because it has no valid zero-point to work from. Hold the Tare button for three seconds after the unit powers up. This forces a fresh zero-calibration and clears the error without a service call.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWeighing readings drifting in the first minute after power-on\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe load cell amplifier in these scales draws current to stabilise its internal reference voltage after a cold start. Until that reference settles — typically within 30 seconds — the output signal drifts, and readings shift by a small but measurable amount. This is not a battery fault. Place no load on the pan for 30 seconds after switching on, then tare the scale before use. Readings will stabilise to within the rated accuracy of ±0.01g once the amplifier reaches a steady operating state.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360293781594,"sku":"BWCS-KRA400SL-1","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360293814362,"sku":"BWCS-KRA400SL-2","price":59.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360293847130,"sku":"BWCS-KRA400SL-3","price":66.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KRA400SL-1.webp?v=1778611048","url":"https:\/\/batteryweb.com\/products\/kern-ew-neg-n-replacement-battery-6v-2100mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
