It matches the OEM part number KAPACC0084090 and fits the original battery bay without modification. Capacity is 950mAh (3.52Wh), sourced to match the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eeS-KAP-Ad VR and ESKAPAD compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions, connector pinout, and BMS handshake protocol — 46.20 × 34.14 × 5.68mm cell with a 3.7V nominal rail. One replacement covers either unit.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through a full charge, a PCI boot sequence, and a transaction loop. The BMS accepted the cell on first handshake, voltage held steady under combined display, wireless, and printer draw, and no overcurrent trips were recorded.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use calibration on payment terminals:\u003c\/strong\u003e\n    After installation, complete one full transaction cycle before deploying in a live environment. The terminal maps battery capacity during normal operation and needs at least one complete power cycle to calibrate the charge indicator correctly.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTerminal rebooting mid-transaction after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe eS-KAP-Ad VR draws a combined load from the display, wireless radio, and receipt printer motor at the point of sale. On a new or partially discharged cell, this simultaneous draw can spike current above the BMS overcurrent threshold, triggering a protective shutdown that looks like a random reboot. The fix is to complete a full charge cycle before first live use — the BMS recalibrates its trip threshold after the cell's first complete charge. If reboots continue, check that the battery contacts are fully seated; a loose connection raises internal resistance and worsens voltage sag under load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTerminal not completing PCI boot sequence after battery installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe KAP ELSE eS-KAP-Ad VR runs a PCI security boot check on every power-on, and that sequence draws a short high-current burst to initialise tamper detection and the secure element. A new cell that has not yet completed one full charge-discharge cycle may sit just below the voltage threshold the BMS requires to release full current for that burst — the terminal stalls or loops at the boot screen. Plug the terminal into the charger until it reads a full charge, then power it on fresh. One complete boot-charge cycle is enough for the BMS to accept normal operating conditions; the sequence will complete at 4.1V or above.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415932502106,"sku":"BWCS-KES008BL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415932534874,"sku":"BWCS-KES008BL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415932567642,"sku":"BWCS-KES008BL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KES008BL-1.webp?v=1779758086","url":"https:\/\/batteryweb.com\/products\/kap-else-es-kap-ad-vr-replacement-battery-37v-950mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
