It replaces OEM part numbers C8872A, 29518, 38403, 46607, 52030, and EI-D-LI1. Fit these cameras directly — voltage and connector match the original pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePhotosmart 912xi and C912 compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions, 7.4V supply rail, and BMS handshake protocol. One cell pack covers either body — no adapter or wiring change needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through camera power-on, LCD activation, and continuous image processing cycles. The BMS held voltage within spec under combined processor and flash-capacitor draw, with no mid-session cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use initialisation on the Photosmart:\u003c\/strong\u003e\n    After fitting a new pack, shoot through at least one full discharge-to-recharge cycle before relying on the battery indicator. The camera's charge gauge maps cell state during actual use — skipping this step causes the indicator to display inaccurate levels for the first several sessions.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Photosmart 912xi cuts out when the flash fires\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 912xi's flash capacitor charges rapidly between shots, pulling a short but steep current spike from the battery. An aged or partially depleted cell cannot sustain voltage through that spike, so the BMS trips the output to protect the cells. The camera reads this as a dead battery and shuts down — even if the indicator showed charge remaining seconds before. A fresh pack with healthy internal resistance handles the spike without triggering cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera shows full battery at power-on, then drops to empty within the first few shots\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the camera's fuel gauge has not yet calibrated to the new cell's discharge curve. The original firmware threshold was set against the aged original pack, so voltage readings from a fresh cell look inconsistent at first. Run one complete discharge cycle — shoot until the camera powers off on its own, then charge fully to 8.4V before the next session. After that first cycle the indicator tracks accurately.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360794607706,"sku":"BWCS-LI1XL-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360794640474,"sku":"BWCS-LI1XL-2","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360794673242,"sku":"BWCS-LI1XL-3","price":42.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LI1XL-1.webp?v=1778616260","url":"https:\/\/batteryweb.com\/products\/hp-photosmart-912xi-replacement-battery-74v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
