It fits the Stinger, Stinger HP, Stinger XT, and Stinger XT HP, along with over 96 additional compatible models. The OEM part numbers are 75175 and 75375.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eStinger family compatibility:\u003c\/strong\u003e\n    The Stinger, Stinger HP, Stinger XT, and Stinger XT HP all share the same 3.6V single-cell Ni-MH format, the same physical housing dimensions, and the same charge contacts. One battery spans the entire platform because Streamlight held those specs consistent across the range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge cycles on a Stinger HP cradle charger. The cell accepted a complete charge without thermal runaway, voltage sag stayed within spec during high-output draw, and the driver held its output level through the expected discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eStinger charger contact care:\u003c\/strong\u003e\n    The Stinger charges through exposed metal contacts on the battery body. If those contacts oxidise — common in patrol vehicles with temperature swings — charge transfer drops and the cell never reaches full capacity. Clean the battery contacts and cradle terminals with a dry cloth before fitting a new cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Stinger dims before the low-battery indicator triggers\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Stinger's driver circuit monitors rail voltage continuously. As a Ni-MH cell discharges, terminal voltage drops gradually rather than sharply — the driver steps output down to protect the LED before the battery indicator registers a fault. This stepdown is intentional, not a defect. What you see as premature dimming is the driver's brownout protection engaging at around 3.0V under load. A new cell with full capacity at 1800mAh pushes that stepdown point further into the discharge cycle, restoring the full high-output window.\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\"\u003eIf the Stinger starts stepping through modes without input, the driver is responding to voltage collapsing and recovering rapidly under load — a sign the cell can no longer hold voltage steady during high-current draw. This is different from normal dimming; the cycling means the driver is repeatedly hitting its cutoff threshold, resetting, and drawing current again. A degraded Ni-MH cell with reduced internal capacity causes this far earlier in the discharge cycle than a fresh cell would. Drop to a lower output mode immediately to stabilise the circuit, and replace the battery before the next shift.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377524015194,"sku":"BWCS-SLX175FT-1","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377524047962,"sku":"BWCS-SLX175FT-2","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377524080730,"sku":"BWCS-SLX175FT-3","price":44.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SLX175FT-1.webp?v=1778767222","url":"https:\/\/batteryweb.com\/products\/streamlight-stinger-replacement-battery-36v-1800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
