It fits the OTG-HH-1, OTG-FF-6, and OTG-VV-5 fittings — all three share the same voltage rail, cell format, and charge controller interface. Dimensions are 49.30 × 28.30 × 26.70mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOTG-HH-1, OTG-FF-6, OTG-VV-5 compatibility:\u003c\/strong\u003e\n    These three fittings run the same 3.6V single-cell Ni-CD charge circuit with identical connector orientation and BMS float voltage. One cell part number covers all three.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full charge cycle on the OTG-HH-1 charge controller. The BMS accepted the cell without fault, reached float charge, and the status LED transitioned from red to green within the expected window.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst test cycle after installation:\u003c\/strong\u003e\n    Hold the test button for the full rated duration within 24 hours of fitting the new cell. This confirms the cell accepts load under real conditions and lets the charge controller register the new capacity before your next scheduled compliance inspection.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eEmergency light failing its duration test after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA freshly installed Ni-CD cell does not arrive at full capacity — storage and shipping leave the cell partially discharged. The charge controller in these fittings applies a trickle float charge, which is slow to top up a depleted cell. If a compliance test runs too soon after installation, the cell has not reached rated capacity and the light will cut out before the test duration ends. Allow at least 24 hours on charge before the first test, then run one full manual cycle to condition the cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator staying red after new cell installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe charge controller in OTG-series fittings checks cell voltage before accepting a charge cycle. A cell that has sat in a warehouse may read below the float acceptance threshold — typically under 3.0V — which holds the indicator in fault or charging red. Connect mains power and leave the fitting undisturbed for at least 12 hours. If the LED has not shifted to green by then, measure the cell terminal voltage directly; a healthy cell will read above 3.2V under no-load conditions at that point.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360394477658,"sku":"BWCS-LMT100LS-1","price":19.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360394510426,"sku":"BWCS-LMT100LS-2","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360394543194,"sku":"BWCS-LMT100LS-3","price":24.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LMT100LS-1.webp?v=1778611162","url":"https:\/\/batteryweb.com\/products\/lumenxl-otg-hh-1-replacement-battery-36v-800mah-ni-cd","provider":"BatteryWeb","version":"1.0","type":"link"}
