It fits the 700, 740, and 744 Calibrators along with the DSP-100 and several additional models sharing the same battery bay and connector. Voltage and capacity figures match the original specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e700 \/ 740 \/ 744 Calibrator platform:\u003c\/strong\u003e\n    These models share a common 7.2V power rail, identical connector footprint, and the same BMS handshake protocol — which is why one pack covers the entire series 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 charge and discharge on a calibrator unit, confirmed the BMS accepted the pack without fault flags, and verified that cell voltage under the instrument's sustained signal-generation load held within acceptable bounds across multiple sessions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration cycle tip:\u003c\/strong\u003e\n    After fitting this pack, run a full calibration cycle through the instrument menu before field deployment. The calibrator maps battery state during that sequence, and skipping it causes premature low-battery warnings on the first measurement session even when the pack is fully charged.\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 calibrator sat unused in a carry case for months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge at roughly 1–2% per day at room temperature. A calibrator stored for several months can drain the pack below the BMS recovery threshold — typically around 5.4V for a 7.2V six-cell pack — at which point the BMS enters a protective sleep state and the charger sees no load. The fix is a slow trickle charge at 0.1C using a compatible Ni-MH charger; most chargers recover the pack within one to two hours once cell voltage climbs back above 5.8V. Do not attempt a fast charge from this state — the BMS may reject it and report a fault.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCalibrator shuts down mid-measurement even with a recently charged pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the instrument's probe or sensor module initialises — the brief current spike at power-up can exceed the BMS overcurrent threshold, triggering a cutoff before any measurement completes. It is not a capacity problem; it is a protection event. The BMS resets after the pack is removed, rested for 30 seconds, and reinstalled. If the shutdowns continue, check that the probe connector is fully seated — a partial connection increases resistance and amplifies the inrush spike.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360744538202,"sku":"BWCS-PF7235XL-1","price":93.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360744570970,"sku":"BWCS-PF7235XL-2","price":109.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360744603738,"sku":"BWCS-PF7235XL-3","price":122.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PF7235XL-1.webp?v=1778616277","url":"https:\/\/batteryweb.com\/products\/fluke-700-calibrator-replacement-battery-72v-3500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
