It matches the original cell's voltage and chemistry, keeping the camera body's power management system satisfied. Capacity is sourced from product data at 25.2Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNP-552 \/ NP-554 \/ V8-series fit:\u003c\/strong\u003e\n    These models share the same 6V Ni-MH voltage rail and physical battery bay dimensions, which is why one cell covers the full range. The connector pinout and BMS voltage thresholds are consistent across this camera family.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge passes on compatible camera bodies. The BMS accepted the cell without triggering a rejection flag, and the charge circuit behaved normally across all test cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle on NP-series bodies:\u003c\/strong\u003e\n    On initial install, run a full charge from within the OEM charger or camera body before shooting. Some ITT NP-series bodies need one full in-body charge cycle before the battery-remaining display reads accurately on a new cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera showing dead battery indicator on a partially charged replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eITT NP-series bodies map battery percentage against a voltage discharge curve calibrated to the original cell. A new Ni-MH replacement has a slightly different discharge curve until it completes a few cycles, so the indicator can read low even when the cell holds a strong charge. This is a display calibration issue, not a cell fault. After two to three full charge-discharge cycles, the readout typically stabilises. If the indicator still reads empty at rest, check resting voltage — a healthy Ni-MH cell at full charge should sit at approximately 1.4V per cell, totalling around 8.4V across a 6-cell pack.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlash not fully recycling between shots on a new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eFlash recycling draws a large burst of current to recharge the capacitor between frames. A new Ni-MH cell that has not completed its first few conditioning cycles delivers slightly lower peak current than a broken-in cell, which can extend recycle time. This is most noticeable in burst shooting or studio-style rapid flash work. Run three full charge-discharge cycles before heavy flash use — peak current delivery improves measurably once the cell chemistry stabilises. If recycling lag persists after conditioning, confirm the cell voltage under load stays above 5.4V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333907316826,"sku":"BWCS-NP66-1","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333907349594,"sku":"BWCS-NP66-2","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333907382362,"sku":"BWCS-NP66-3","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP66_1.webp?v=1778213590","url":"https:\/\/batteryweb.com\/products\/itt-np-552-replacement-battery-6v-4200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
