It matches the original cell configuration and BMS handshake requirements of the platform. Capacity is sourced from cell data — 24.79Wh per pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePLS and 6XG platform compatibility:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, connector pinout, and BMS communication protocol. Swapping between them works because the instrument queries the pack over the same data line — voltage rail and handshake logic are identical across this family.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack under simulated sensor-load draw and monitored BMS response at probe initialisation. The protection circuit handled the current spike at power-up without tripping to lockout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration step:\u003c\/strong\u003e\n    After installing this pack, run a full calibration cycle through the instrument menu before field deployment. The instrument 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 PLS or 6XG sat unused in a carry case for months\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge slowly during storage. If the pack voltage drops below roughly 2.5V per cell, the BMS trips into deep-discharge lockout and the instrument will not recognise the pack at all. The charger may also show no activity. To recover, apply the OEM charger for at least 30–45 minutes before attempting to power the instrument on — the BMS needs to see a minimum threshold voltage before it exits lockout and re-enables the output rail.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eReadings resetting or drifting mid-session during sustained sensor logging\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSustained sensor load draws more current than the instrument draws at idle, and an aged or partially charged cell shows voltage sag under that load. When voltage briefly drops below the instrument's internal cutoff threshold, the measurement module resets — you lose the active log. This is not a firmware issue. Charge the pack fully before a logging session and confirm resting voltage reads above 3.9V before starting data capture.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360453427290,"sku":"BWCS-FBP500SL-1","price":303.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360453460058,"sku":"BWCS-FBP500SL-2","price":363.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360453492826,"sku":"BWCS-FBP500SL-3","price":407.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FBP500SL-1.webp?v=1778614684","url":"https:\/\/batteryweb.com\/products\/fluke-6xg45-replacement-battery-37v-6700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
