It fits the 10D, 20K, 2006I, BT70, and over 680 additional models in the same OEM battery family. Voltage and connector spec match the original cell exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBroad NP-series compatibility:\u003c\/strong\u003e\n    These camera bodies share the same 6V Ni-MH battery bay and contact layout across multiple generations. Sony standardised the NP footprint across this lineup, so one cell covers a wide range of bodies without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a compatible Sony body. The BMS accepted the cell cleanly, and voltage held steady across the mid-discharge curve with no premature low-battery flags triggered.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eNi-MH memory effect management:\u003c\/strong\u003e\n    Unlike Li-ion, Ni-MH cells in this family can develop voltage depression if repeatedly charged from a partial state. Run the cell down fully through normal shooting before recharging — do this on the first three cycles to establish a clean capacity baseline.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSony camera body rejecting a new NP-series cell on first install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome Sony Cyber-shot bodies perform a voltage handshake when a new cell is inserted cold. If the resting voltage of the replacement cell sits below the camera's acceptance threshold, the body displays a battery error or simply refuses to power on. This is a BMS authentication check, not a faulty cell. Insert the battery and place the camera on charge via the OEM charger for a full cycle before attempting to power on — this brings the cell voltage up to a level the body recognises. After one complete charge cycle, the body accepts the cell and the battery indicator displays correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells have a flatter discharge curve than Li-ion, which makes voltage-based fuel gauge readings less accurate — especially during the first few cycles on a new cell. The camera maps battery percentage to voltage thresholds calibrated for a partially aged OEM cell, so a fresh replacement can cause the indicator to skip or drop suddenly. This is a calibration mismatch, not cell failure. Run three full discharge-to-charge cycles and the indicator will settle as the camera re-maps its thresholds to the actual discharge curve of the new cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43336963522650,"sku":"BWCS-NP55-1","price":35.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43336963555418,"sku":"BWCS-NP55-2","price":41.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43336963588186,"sku":"BWCS-NP55-3","price":45.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP55-1.webp?v=1778213590","url":"https:\/\/batteryweb.com\/products\/sony-10d-replacement-battery-6v-2100mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
