It slots into the same battery compartment as the original cell and runs the imaging sensor, flash capacitor circuit, and all internal logic. Capacity is 2100mAh — use the Capacity field above, not web search figures.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eA1200 series compatibility:\u003c\/strong\u003e\n    These models share the same 6V voltage rail, battery compartment form factor, and BMS charge-acceptance threshold. A single cell design covers the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through a full charge-discharge sequence and confirmed the BMS accepted the cell, the charge-complete signal triggered correctly, and the flash capacitor recharged between shots without voltage sag.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on Ni-MH camera cells:\u003c\/strong\u003e\n    Ni-MH cells in camera bodies often require one full charge cycle completed inside the camera body or OEM charger before the battery-remaining indicator reads accurately. Do this before your first shoot — skipping it causes the indicator to drop prematurely and trip a false low-battery warning mid-session.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlash output dropping mid-shoot on a new Ni-MH cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells have a flatter discharge curve than Li-ion, which means voltage holds steady for most of the charge cycle and then drops sharply near the end. The flash capacitor recharges from the battery rail directly — when cell voltage sags under the capacitor's recharge current draw, recycle time increases and guide number drops. If flash output feels inconsistent on a new cell, check the battery-remaining indicator first. A cell reading below 20% on a Ni-MH camera will show this behaviour even if the camera body is still operational.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping around erratically on the camera display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eCamera battery indicators are calibrated against the discharge curve of the original OEM cell. A new Ni-MH replacement cell may have a slightly different internal resistance profile, causing the camera's voltage-threshold mapping to read the state of charge inconsistently during the first few cycles. This usually corrects itself after two to three full charge-discharge cycles as the BMS learns the cell's actual voltage behaviour. Run two complete cycles — charge to full, shoot until the camera shuts down — and the percentage display will stabilise.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333889458266,"sku":"BWCS-NP55-1","price":35.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43333889491034,"sku":"BWCS-NP55-2","price":41.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43333889523802,"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\/telefunken-a1200-replacement-battery-6v-2100mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
