It fits the OH3502 series handheld scanners used in retail, warehousing, and inventory environments. Voltage and cell chemistry match the original pack specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOH3502 series fit:\u003c\/strong\u003e\n    The OH3502 and OH3502 1D share the same battery bay dimensions, connector pinout, and BMS communication protocol — one pack covers both variants without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on the OH3502 platform. The BMS accepted the cell without error codes, and the protection circuit responded correctly to over-discharge and over-current conditions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation:\u003c\/strong\u003e\n    After installing this pack, seat the scanner in its cradle and let it complete a full charge cycle before triggering scans. The OH3502's scan trigger draws peak inrush current — highest when the cell is near minimum — and a fully charged cell prevents false BMS trips at shift start.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCradle showing charging error on a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe OH3502 cradle communicates with the battery through spring-loaded dock contacts. If those contacts have oxidation or debris from the old pack, the cradle reads elevated resistance and flags a charging fault — not a pack defect. Remove the scanner, wipe the gold contacts on both the battery and the cradle dock with a dry cloth, then reseat firmly. If the error clears, the dock contacts were the cause. If the error persists after reseating, check that the cradle supply voltage is stable at 5V.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScanner losing wireless connection during rapid scan bursts\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe OH3502 draws current from two loads simultaneously during a wireless scan burst: the imager or laser and the radio transmitting data back to the host. Combined inrush can spike high enough to trigger the BMS undervoltage protection if the cell voltage is already low. The scanner drops the wireless link before the imager powers down because the radio handshake is the first casualty of voltage sag. Charge the pack to full before the shift and avoid running scans when the battery indicator shows one bar — that threshold sits around 3.4V, where combined draw margin disappears.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324677947482,"sku":"BWCS-HYH350BL-1","price":247.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324677980250,"sku":"BWCS-HYH350BL-2","price":295.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324678013018,"sku":"BWCS-HYH350BL-3","price":331.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HYH350BL-1.webp?v=1778121683","url":"https:\/\/batteryweb.com\/products\/honeywell-oh3502-1d-replacement-battery-37v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
