It uses OEM part number Nova4AH and fits the 5000 series directly. The Nova 5000 collects environmental and scientific measurements, and this pack keeps it running through extended classroom experiments and field surveys.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNova 5000 compatibility:\u003c\/strong\u003e\n    The 5000 series uses a 6V Ni-MH pack with a specific connector and BMS handshake. This replacement matches that voltage rail and connector pinout, so the logger recognises the pack and reports charge state correctly from the first boot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through sensor initialisation cycles and sustained logging loads on the bench. The BMS handled the current spike at probe power-up without tripping, and voltage held stable under continuous multi-sensor draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use calibration step:\u003c\/strong\u003e\n    After installing this pack, run a full calibration cycle through the Nova 5000 instrument menu before field deployment. The logger maps battery state during calibration — skipping this step causes premature low-battery warnings on the first measurement session, even with a fully charged pack.\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 Nova 5000 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. If a pack sits unused long enough, cell voltage drops below the BMS recovery threshold and the pack enters a protection state. At that point, the logger either shows no charge or refuses to power on, even after placing it on charge. To recover the pack, connect it to the charger and leave it for a full charge cycle — most BMS circuits re-initialise once voltage climbs back above 5.4V.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eNova 5000 shuts down mid-logging session with no low-battery warning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when sustained sensor load pulls voltage down faster than the logger's threshold indicator tracks. The display shows adequate charge, then the unit cuts out without warning. The cause is voltage sag under continuous multi-sensor draw — the pack voltage dips below the cutoff threshold before the indicator catches up. If this occurs, let the pack rest for two minutes and check open-circuit voltage: a healthy cell should read above 5.8V at rest.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360785530970,"sku":"BWCS-NV5000SL-1","price":305.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360785563738,"sku":"BWCS-NV5000SL-2","price":365.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360785596506,"sku":"BWCS-NV5000SL-3","price":410.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NV5000SL-1.webp?v=1778616277","url":"https:\/\/batteryweb.com\/products\/nova-5000-classroom-data-logger-replacement-battery-6v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
