It fits the Midiform (03.5421), UV Form (03.5408), and compatible variants sharing part number 03.5316. Dimensions are 57.50 × 28.90 × 8.80mm — confirm these against your original cell before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMidiform and UV Form compatibility:\u003c\/strong\u003e\n    Both the Midiform and UV Form share the same battery bay dimensions and draw from the same 3.7V cell with identical connector pinout. The BMS protection circuit handles over-discharge and over-current cutoff the same way across both models.\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 the Midiform platform. The BMS protection tripped correctly at low-voltage cutoff, and the cell held capacity within expected tolerance across repeated cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSingle-cell swap rule:\u003c\/strong\u003e\n    The Midiform runs on one cell. If your flashlight has been in service for a long time, check the battery contacts for corrosion before fitting the new cell — corroded contacts increase resistance and cause the driver to step down output earlier than the cell voltage warrants.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSCANGRIP Midiform dimming before the battery indicator hits low\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Midiform's driver circuit monitors cell voltage directly. When voltage sags under load — even briefly — the driver steps down output to protect the cell from a deep-discharge event. This happens before the indicator LED signals low battery because the indicator threshold is set conservatively. A degraded or partially charged cell sags further under high-output draw, triggering the stepdown earlier. If you see this on a fresh cell, check contact resistance first — clean the contacts and measure voltage under load with a multimeter; it should hold above 3.5V.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlashlight cycling through modes on its own near end of charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eMode-cycling near end of charge is a brownout loop in the driver. The cell voltage drops below the driver's minimum operating threshold, the driver resets, the cell partially recovers, and the cycle repeats. This is not a fault in the replacement cell — it means the cell is genuinely depleted and the driver is protecting it. Switch to the lowest output mode to get remaining usable light, then charge immediately. After a full charge, cell voltage at rest should read between 4.1V and 4.2V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377490722906,"sku":"BWCS-SGM540SL-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377490755674,"sku":"BWCS-SGM540SL-2","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377490788442,"sku":"BWCS-SGM540SL-3","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SGM540SL-1.webp?v=1778767172","url":"https:\/\/batteryweb.com\/products\/scangrip-midiform-replacement-battery-37v-1600mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
