It powers the imaging sensor, processor, and all onboard functions. Fit the same way as the original — same dimensions at 43.70 × 31.30 × 7.00mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDC E53+ platform compatibility:\u003c\/strong\u003e\n    The E53, E53+, E63+, and E43 all share the NP-900 form factor and 3.7V voltage rail. The connector and cell housing are identical across this range, so one replacement covers the whole family.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the DC E53+ body using the OEM charger. The BMS accepted the cell without error flags, and voltage held steady across the discharge curve through still capture and playback.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge cycle on this camera:\u003c\/strong\u003e\n    Charge the new cell fully inside the camera body or OEM charger before your first shoot. Some BenQ camera BMS systems need one full charge cycle completed in-body to calibrate the battery-remaining indicator accurately.\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 erratically on the DC E53+ display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the camera maps its fuel gauge to a discharge curve calibrated against the original cell. A new replacement cell has a slightly different discharge profile until the BMS has logged one full cycle. The indicator can jump from 80% to 20% mid-shoot, then recover. Run one complete charge-to-full, shoot-to-empty cycle and the display will track correctly from that point forward.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera showing dead battery indicator on a partially charged replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DC E53+ reads cell voltage at startup and compares it against a minimum threshold. A replacement cell shipped in storage mode may sit below 3.0V, which the camera reads as depleted. Place the cell in an OEM charger first — do not insert it cold into the camera body. Once the charger brings it above 3.6V, the camera will power on and accept the cell normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333834899546,"sku":"BWCS-NP900-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333834932314,"sku":"BWCS-NP900-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333834965082,"sku":"BWCS-NP900-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP900-1.webp?v=1778213259","url":"https:\/\/batteryweb.com\/products\/benq-dc-e53-replacement-battery-37v-600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
