It fits the Samsung HMX-E10WP, HMX-E10BP, HMX-E100P, and HMX-E10 compact camcorders. The BP-90A form factor is slim — 49.50 x 34.05 x 4.90mm — and slots directly into the battery compartment on these pocket camcorders.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHMX-E10 series fit:\u003c\/strong\u003e\n    These camcorder models share the same battery bay dimensions, 3.7V rail, and BP-90A connector pinout. The BMS communication protocol is identical across the HMX-E10WP, HMX-E10BP, HMX-E100P, and HMX-E10 variants, so one cell covers the full family.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran charge and discharge cycles through a Samsung HMX-E10 body. The BMS accepted the cell without error, reported charge state correctly, and held the cutoff voltage within the expected range at end of discharge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle on the HMX-E10WP:\u003c\/strong\u003e\n    Insert the new cell and charge it fully inside the camera body before your first recording session. Some Samsung camcorder BMS firmware maps battery-remaining percentage to an internal reference that calibrates on the first in-body charge — skipping this step can cause the indicator to read inaccurately throughout the cell's life.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the HMX-E10WP shows a dead battery indicator on a freshly charged replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe HMX-E10WP reads battery level by mapping the cell's discharge curve against a stored voltage threshold table. A new cell that hasn't completed an in-body charge cycle can present a resting voltage the firmware doesn't recognise as \"full.\" The camera interprets this as a depleted or missing cell and shows the low-battery icon even though the cell holds a full charge. One complete charge cycle from inside the camera body resets this — after that, the indicator tracks accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the HMX-E10WP display mid-recording\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the camera's voltage-to-percentage mapping doesn't align with the new cell's discharge curve during the first few cycles. The firmware is reading real voltage correctly, but translating it against a reference calibrated to the original cell. The percentage can jump from 60% to 20% without warning. Run two full charge-discharge cycles through the camera body — after that, the indicator stabilises because the BMS has enough discharge history to recalibrate its threshold mapping.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333808193626,"sku":"BWCS-BP90A-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333808226394,"sku":"BWCS-BP90A-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333808259162,"sku":"BWCS-BP90A-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BP90A_1.webp?v=1778213126","url":"https:\/\/batteryweb.com\/products\/samsung-hmx-e10wp-replacement-battery-37v-800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
