It fits the Minolta DG-5W and DiMAGE A200 digital cameras. Both models share the same battery bay geometry, voltage rail, and BMS handshake protocol, so one cell covers both bodies.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDG-5W and DiMAGE A200 compatibility:\u003c\/strong\u003e\n    Both cameras run an identical 7.4V power rail with the same connector pin layout and BMS communication sequence. The NP-800 slot dimensions — 52.00 × 32.20 × 15.70mm — are shared across both bodies, so the same cell seats and latches correctly in either chassis.\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 DiMAGE A200 body. The BMS accepted the cell without error flags, voltage held steady across sustained burst shooting, and the charge indicator tracked the expected discharge curve without erratic jumps.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle on the DiMAGE A200:\u003c\/strong\u003e\n    Insert the new cell and run a full charge through the camera body or OEM charger before your first shoot. The A200's BMS maps its battery-remaining display to a discharge curve it calibrates on the first charge cycle — skipping this step often causes the percentage indicator to read incorrectly 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\"\u003eWhy the DiMAGE A200 battery indicator drops suddenly from 50% to empty\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe A200 uses a voltage-threshold system to estimate remaining charge rather than a coulomb counter. A new cell has a slightly different discharge curve than the original NP-800, so the thresholds can misfire — the indicator looks stable, then collapses at the knee of the curve. This is a calibration issue, not a cell fault. Running two or three full charge-discharge cycles through the camera body brings the indicator back into alignment with the actual cell capacity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDiMAGE A200 showing \"no battery\" with a fully charged replacement cell installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the BMS has not yet completed an authentication handshake with the new cell. The camera reads an unrecognised voltage profile on first contact and throws a rejection flag rather than a low-battery warning. Remove the cell, reinsert it firmly until the latch clicks, then power the camera on. If the error persists, place the cell in the OEM charger until the charge LED confirms a full charge — the handshake typically completes during that first charge cycle and the body accepts the cell at 7.4V nominal.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333850824794,"sku":"BWCS-ENEL1-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333850857562,"sku":"BWCS-ENEL1-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333850890330,"sku":"BWCS-ENEL1-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ENEL1-1.webp?v=1778213290","url":"https:\/\/batteryweb.com\/products\/minolta-dg-5w-replacement-battery-74v-700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
