It fits both the OH3502 1D and OH3502 variants. Capacity is rated at 12.4Wh, matching the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOH3502 and OH3502 1D fit:\u003c\/strong\u003e\n    Both models run the same 3.7V single-cell architecture with an identical connector and BMS handshake profile. One pack covers either unit — no firmware or hardware difference affects compatibility between the two.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the OH3502 charging circuit and monitored the BMS during scan-trigger inrush events. The protection IC handled repeated trigger bursts without false low-voltage cutoff across the test run.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift prep for pick-and-pack environments:\u003c\/strong\u003e\n    After installing this pack, seat the scanner in its cradle and run a full charge cycle before the first shift. Scan-trigger inrush current peaks when the cell sits near minimum charge — a fully charged cell prevents BMS trips during the first high-frequency scan burst of the day.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCradle showing a charging error after fitting a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe OH3502 cradle reads pack state through pogo-pin contacts on the battery base. If those contacts carry oxidation or debris from handling, the dock controller sees high resistance and flags a charge fault. This is not a cell defect — it is a contact issue. Wipe the gold contacts on both the battery and the cradle with a dry lint-free cloth, then reseat the scanner firmly until the status LED confirms charging.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScanner drops wireless connection during rapid barcode scan bursts\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe OH3502 draws simultaneously from the radio module and the laser or imager during a rapid scan sequence. That combined current spike can pull the cell voltage below the BMS hold threshold if the pack is already partly depleted. The radio link drops first because the scanner prioritises the imager circuit under voltage sag. Start the shift with a fully charged pack — a cell at 4.2V sustains both loads without sagging below the 3.2V BMS cutoff.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324677685338,"sku":"BWCS-HYH350BX-1","price":367.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324677718106,"sku":"BWCS-HYH350BX-2","price":439.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324677750874,"sku":"BWCS-HYH350BX-3","price":493.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HYH350BX-1.webp?v=1778121683","url":"https:\/\/batteryweb.com\/products\/honeywell-oh3502-1d-replacement-battery-37v-3350mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
