It replaces OEM part 57-0962 directly. Capacity is 25.2Wh — matching the original specification from the product data.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePanjam, VPT-CP, and VPN-CP platform fit:\u003c\/strong\u003e\n    These three AMX instruments share the same 7.2V battery bay, connector pinout, and BMS handshake protocol. One pack covers all three. No adapter or wiring change needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through probe initialisation and sustained sensor logging sequences. The BMS held stable through the current spike at probe power-up and did not trip under continuous measurement load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePre-deployment calibration cycle:\u003c\/strong\u003e\n    After fitting this pack, run a full calibration cycle from the instrument menu before heading into the field. The instrument maps battery state during calibration — skipping it causes the low-battery indicator to fire prematurely on the first measurement session.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS lockout after the instrument sat unused in a carry case for months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge during storage, and if the pack drops below the BMS recovery threshold, the charger may show no activity and the instrument will not power on. This is a protection state — not a dead cell. Connect the battery to the charger and leave it for at least 30 minutes before assuming it has failed. Most chargers will begin a trickle recovery cycle and restore the pack to a chargeable voltage above 6.0V.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eReadings resetting or dropping out mid-logging session\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when sustained sensor load pulls the pack voltage below the instrument's operating threshold for a split second. It is not always visible on the charge indicator because the voltage recovers immediately after the dropout. The root cause is usually a partially degraded original pack — not a charger fault. A fresh pack at full charge holds voltage steady under continuous sensor draw, and the logging session completes without reset.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360731824218,"sku":"BWCS-AMP570SL-1","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360731856986,"sku":"BWCS-AMP570SL-2","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360731889754,"sku":"BWCS-AMP570SL-3","price":70.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AMP570SL-1.webp?v=1778616208","url":"https:\/\/batteryweb.com\/products\/amx-panjam-replacement-battery-72v-3500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
