It fits the VL-AH50S, VL-AH1510, VL-AH131E, VL-AH1500, and over 140 additional Sharp camcorder models. Capacity is rated at 13.68Wh — matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVL-AH series compatibility:\u003c\/strong\u003e\n    These Sharp camcorders share a common 3.6V single-cell Ni-MH battery bay with the same connector pinout and BMS communication protocol. The BT-H11 format covers the full range without modification.\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 VL-AH series hardware. The BMS accepted the pack without error flags, and voltage held steady across both record and playback loads.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on Ni-MH cells:\u003c\/strong\u003e\n    Ni-MH chemistry benefits from a full charge cycle completed inside the camera body or OEM charger on first use. This allows the camcorder's charge controller to baseline the cell and display accurate remaining capacity.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the VL-AH50S battery indicator reads empty on a freshly charged cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells have a flatter discharge curve than lithium-based chemistries. The Sharp VL-AH series maps its battery indicator against voltage thresholds tuned to the original cell's discharge profile. A new replacement cell may sit at a slightly different resting voltage after its first charge, causing the indicator to misread. After one full charge-to-discharge cycle inside the camera, the indicator typically re-aligns with the cell's actual capacity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamcorder cuts to low-battery warning during recording but recovers on standby\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when sustained video recording draws more current than the camcorder's low-voltage threshold allows. The combined load of the image sensor, LCD, and tape or recording mechanism pulls the cell voltage down temporarily under load. When the camera idles, the cell voltage recovers and the warning clears. If the behaviour repeats within the first few cycles, complete two full charge-discharge cycles — Ni-MH cells reach stable capacity after conditioning, not straight from storage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333821333594,"sku":"BWCS-BTH11-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333821366362,"sku":"BWCS-BTH11-2","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333821399130,"sku":"BWCS-BTH11-3","price":51.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BTH11-1.webp?v=1778213245","url":"https:\/\/batteryweb.com\/products\/sharp-vl-ah50s-replacement-battery-36v-3800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
