It replaces OEM part 5x2-3A600 and fits both the Memobox and Analyzers Memobox configurations. Capacity is 1100mAh (6.6Wh), matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMemobox and Analyzers Memobox compatibility:\u003c\/strong\u003e\n    Both units share the same 6V bus, physical form factor, and BMS handshake protocol — this pack covers either variant without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the Memobox charge and discharge sequence, confirmed BMS communication at start-up, and verified the cell voltage held within spec across sustained sensor logging load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use calibration cycle:\u003c\/strong\u003e\n    After installing, run a full calibration cycle through the instrument menu before taking it into the field. The Memobox maps battery state during calibration — skipping this step causes premature low-battery warnings during your 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 Memobox sat unused in a carry case for months\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge over time, and if the pack drops below roughly 4.8V total, the BMS enters a protection state and refuses to accept a standard charge cycle. The Memobox charger interprets this as a faulty pack and stops the charge sequence before the cells recover. To break the lockout, apply a slow pre-charge at low current — most multi-chemistry chargers have a conditioning or recovery mode that handles this. Once the pack climbs back above 5.4V, the BMS clears the lockout and normal charging resumes.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMemobox shuts down mid-logging session with no low-battery warning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage dropout under sustained sensor load, not a capacity issue. When the instrument drives multiple probe channels simultaneously, the combined current draw pulls cell voltage down sharply — enough to trip the BMS undervoltage threshold before the display has time to flag a warning. The instrument cuts power to protect the cells. Charge the pack fully, then reduce simultaneous probe channels if the shutdown repeats. A healthy pack should hold above 5.4V under normal logging load; if it collapses below that under light load, the cells need replacement.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360706003034,"sku":"BWCS-FBP600SL-1","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360706035802,"sku":"BWCS-FBP600SL-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360706068570,"sku":"BWCS-FBP600SL-3","price":36.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FBP600SL-1.webp?v=1778616161","url":"https:\/\/batteryweb.com\/products\/fluke-memobox-replacement-battery-6v-1100mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
