It also fits the Engine Analyser and F00E900018 units that share the same battery bay and connector. OEM part numbers 8489 and B11543 both cross-reference to this pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMTS 5200 and 03006735 platform fit:\u003c\/strong\u003e\n    These models share a common 7.2V cell stack, identical connector pinout, and the same BMS handshake sequence, so one pack covers the full platform without adapter wiring.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the MTS 5200 charge and measurement sequence. The BMS handled probe initialisation current without tripping, and the instrument accepted the pack's state-of-charge signal without throwing a battery fault code.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use calibration on the MTS 5200:\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 MTS 5200 sat unused in a carry case for months\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge during storage, and if the pack drops below roughly 5.0V total, the BMS enters a protective lockout state. In this condition the instrument either shows no battery icon or refuses to power on at all. A standard charger will not recover the pack from this state because it detects zero current draw and assumes a fault. To recover, place the pack on a Ni-MH charger with a conditioning or recovery mode — this applies a low trickle current to bring cell voltage back above the BMS wake threshold before attempting a full charge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eReadings resetting or dropping during a sustained logging session\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the instrument runs a long sensor logging sequence, the combined draw from the probe module and data processing can pull pack voltage down sharply under load. If cell voltage dips below the instrument's cutoff threshold mid-session, the MTS 5200 resets the active measurement rather than saving it. This is not a faulty pack — it is a sign the cells have capacity-faded past the point where sustained load is manageable. Confirm cell health by checking resting voltage after a full charge: a healthy 7.2V Ni-MH pack should read 8.4–8.6V at rest within 15 minutes of leaving the charger.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360780714074,"sku":"BWCS-VTC543SL-1","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360780746842,"sku":"BWCS-VTC543SL-2","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360780779610,"sku":"BWCS-VTC543SL-3","price":47.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VTC543SL-1.webp?v=1778616277","url":"https:\/\/batteryweb.com\/products\/vetronix-03006735-replacement-battery-72v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
