It powers the imaging sensor, autofocus, LCD display, and flash system. Swap it in when the original cell no longer holds a usable charge.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSamuria 2100DG fit:\u003c\/strong\u003e\n    The 2100DG uses a single-cell 3.7V Li-ion pack at fixed dimensions — 71.00 × 19.70 × 19.70mm. This cell matches that form factor and the voltage rail the camera's BMS expects on startup.\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, monitoring BMS handshake and cutoff behaviour under combined flash-plus-sensor draw. No false low-battery trip on a full cell.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle initialisation on the 2100DG:\u003c\/strong\u003e\n    Run one full charge cycle through the camera body or OEM charger before your first shoot. The 2100DG BMS calibrates its battery-remaining indicator against the first charge profile it sees — skipping this step causes erratic percentage readings from the start.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlash capacitor recharge slowing at low cell voltage on the 2100DG\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Samuria 2100DG's flash capacitor pulls a sharp current spike each time it recharges between shots. Early in the cell's life, voltage recovers fast enough that recycling feels instant. As the cell approaches the bottom of its discharge curve — typically below 3.5V — that spike causes a brief sag, and the capacitor takes noticeably longer to reach full charge. The camera may still show one or two bars of battery remaining when this happens. If flash recycle time stretches at that point, the cell is functionally depleted even if the indicator disagrees — swap the battery rather than continuing to shoot.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the 2100DG display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 2100DG maps its battery indicator to a voltage-threshold table calibrated to the original cell's discharge curve. A replacement cell with a slightly different internal resistance or discharge profile can read against those thresholds unevenly, causing the display to jump from 80% to 40% or stall at a fixed number before dropping suddenly. This is a display mapping issue, not a cell fault. Run one full charge-to-discharge cycle inside the camera body — the BMS resamples the curve and the indicator stabilises from the next charge onward.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333918982234,"sku":"BWCS-NB111-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333919015002,"sku":"BWCS-NB111-2","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333919047770,"sku":"BWCS-NB111-3","price":37.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NB111-1.webp?v=1778213576","url":"https:\/\/batteryweb.com\/products\/yashica-samuria-2100dg-replacement-battery-37v-2400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
