It restores power to the camera body so you can return to shooting video and stills. No OEM part number exists for this cell — fit is confirmed by voltage, physical dimensions (53.20 × 35.30 × 7.10mm), and connector polarity.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDV5311 and DV5311HD compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions and 3.7V supply rail. The connector pinout and physical envelope are identical across the two variants, so one cell covers both.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the DV5311 body, monitoring the BMS charge acceptance and discharge curve. The protection circuit responded correctly to end-of-discharge cutoff, and the camera body accepted the cell without an incompatibility flag on first install.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle charge protocol for the DV5311:\u003c\/strong\u003e\n    Insert the new cell and run a full charge inside the camera body before your first recording session. The DV5311's battery-level indicator calibrates against the cell's discharge curve during that first in-body charge — skipping this step can cause the indicator to read incorrectly for the first few cycles.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping on the DV5311 display after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DV5311 maps its battery-level indicator to a fixed voltage-threshold table calibrated against the original cell's discharge curve. A new replacement cell — even at the same rated capacity — can have a slightly different mid-discharge voltage profile. The camera reads an unexpected voltage at a given state of charge and jumps the indicator up or down by 20–30%. Run two or three full charge and discharge cycles through the camera body and the indicator will stabilise as the BMS learns the new cell's curve. After the third cycle, the display should track accurately from 4.2V full charge down to the 3.0V cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDV5311 showing dead battery symbol immediately after inserting a charged replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis usually happens when the replacement cell arrives in a partially discharged storage state below the camera's minimum detection threshold. The DV5311 body will not power on if it reads terminal voltage below roughly 3.2V on insertion. Place the cell in an external Li-ion charger or insert it and connect the camera to USB to trickle-charge it past that threshold first. Once the cell climbs above 3.4V, the camera will recognise it and power on normally. If the dead battery symbol persists above 3.5V, check the battery contacts in the bay for oxidation and clean them with a dry cotton swab.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333913018458,"sku":"BWCS-NP60FU-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333913051226,"sku":"BWCS-NP60FU-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333913083994,"sku":"BWCS-NP60FU-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP60FU-1.webp?v=1778213591","url":"https:\/\/batteryweb.com\/products\/easypix-dv5311-replacement-battery-37v-1050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
