It fits the Cyber-shot DSC-T7, DSC-T7\/B, and DSC-T7\/S compact digital cameras. Voltage and cell format match the OEM specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDSC-T7 variant coverage:\u003c\/strong\u003e\n    The T7, T7\/B, and T7\/S share the same battery bay geometry and BMS handshake protocol. All three accept the NP-FE1 cell format — same contact orientation, same voltage rail, same charge termination logic.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the DSC-T7 body and a compatible OEM charger. The BMS accepted charge termination correctly and reported cell status without error flags on the camera's status screen.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle on the T7:\u003c\/strong\u003e\n    Run one full charge cycle through the camera body or OEM charger before your first shoot. The T7's battery-remaining indicator maps voltage thresholds to display segments — a cell that hasn't been fully cycled once can cause the indicator to read inaccurately from the first frame.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSony DSC-T7 BMS rejecting a third-party cell on first install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe T7's BMS performs a voltage-presence check when the cell is inserted. If the replacement cell ships in a low-voltage storage state, the camera may display a battery error or refuse to power on entirely. This is not a fault with the cell — it is the BMS rejecting a voltage reading below its minimum acceptance threshold. Place the battery in the OEM charger for a full charge cycle before inserting it into the camera body. Once the cell reaches approximately 4.2V, the BMS accepts it without further error.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the DSC-T7 display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe T7 uses a stepped voltage-threshold system to estimate remaining charge — it does not use a fuel gauge IC. A new replacement cell has a slightly different discharge curve than the aged OEM cell the camera was originally calibrated against. This causes the indicator to jump segments non-linearly, particularly between 50% and 20%. The fix is two full charge-discharge cycles through the camera body. After that, the BMS recalibrates its threshold mapping to the new cell's actual discharge curve and the display stabilises.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333923242074,"sku":"BWCS-FE1-1","price":29.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43333923274842,"sku":"BWCS-FE1-2","price":33.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43333923307610,"sku":"BWCS-FE1-3","price":37.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FE1-1.webp?v=1778213575","url":"https:\/\/batteryweb.com\/products\/sony-cyber-shot-dsc-t7-replacement-battery-37v-450mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
