It fits the Tvs Digital body directly, matching the original connector and cell dimensions of 53.00 × 35.30 × 11.00mm. Voltage and capacity are matched to the original to keep the camera's battery indicator reading correctly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eContax Tvs Digital compatibility:\u003c\/strong\u003e\n    The Tvs Digital uses a single-cell 3.7V Li-ion pack with a proprietary BP-1500S form factor. The contact layout and cell dimensions must match exactly — an off-spec cell will not seat correctly in the battery compartment or close the door.\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 the Tvs Digital body. The BMS accepted the cell without error flags, and the camera powered on and advanced through menus without resetting mid-session.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle on the Tvs Digital:\u003c\/strong\u003e\n    Run one full charge through the camera body or OEM charger before shooting. The Tvs Digital maps its battery-remaining display against a charge curve it learns on that first cycle — skipping it causes the indicator to drop erratically early in a session.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Tvs Digital shows a dead battery indicator on a partially charged replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Contax Tvs Digital uses voltage-threshold mapping to estimate remaining charge. A new third-party cell has a slightly different discharge curve than the original BP-1500S, so the camera can misread the state of charge at the lower thresholds. This shows up as the battery icon dropping to empty while the cell still has usable capacity. One full charge-discharge cycle from within the camera body recalibrates the threshold mapping and corrects the display.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlash not fully recycling between shots on a new BP-1500S cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Tvs Digital's built-in flash pulls a sharp current spike to recharge its capacitor after each shot. At the end of a cell's discharge curve — typically below 3.5V — that recharge current sags and the capacitor takes longer to reach full charge. If the flash indicator clears but the output looks weak or inconsistent, check the battery level first. Charge the cell back to 3.7V and the recycling time returns to normal.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333868847194,"sku":"BWCS-NP120FU-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333868879962,"sku":"BWCS-NP120FU-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333868912730,"sku":"BWCS-NP120FU-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP120FU-1.webp?v=1778213403","url":"https:\/\/batteryweb.com\/products\/kyocera-contax-tvs-digital-replacement-battery-37v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
