It fits the IH21 RFID, IH21A0014, and H21 RFID reader variants. OEM part number 318-060-001 cross-references directly to this pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIH21 RFID and IH21A0014 compatibility:\u003c\/strong\u003e\n    Both models run the same 3.7V single-cell architecture with identical connector pinout and BMS handshake protocol. A single cell replacement covers the full IH21 platform without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through simulated scan burst sequences — rapid-fire trigger pulls combined with wireless polling load. The BMS held cutoff thresholds correctly and did not trip under combined inrush draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift prep for IH21 scanners:\u003c\/strong\u003e\n    After installing, seat the scanner in its charging cradle for a full charge cycle before running it on the floor. Scan trigger inrush current is highest when the cell is near minimum charge, and a pre-charged pack prevents false BMS trips on the first pick-and-pack shift.\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 after fitting a new IH21 pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIH21 charging docks read pack status through the contact pins on the battery's lower edge. Dock contact resistance rises when those pins have oxidation or debris from previous packs. The cradle interprets a dirty contact as a fault condition and throws a charging error even though the new pack is fine. Wipe the battery contacts and the dock contacts with a dry cloth, reseat the pack firmly, and the error clears at the dock's next polling cycle.\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\"\u003eDuring a fast scan sequence, the IH21 draws current simultaneously from the imager, the wireless radio, and the processor — all three spike at once. If the cell voltage sags under that combined load, the wireless subsystem drops off first because the imager and CPU are prioritised by the device firmware. This looks like a connectivity drop rather than a battery issue, which is why it gets misdiagnosed. A fresh, fully charged cell maintains voltage above the radio's minimum threshold through the burst and keeps the connection stable.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324729917530,"sku":"BWCS-HYH210BL-1","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324729950298,"sku":"BWCS-HYH210BL-2","price":49.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324729983066,"sku":"BWCS-HYH210BL-3","price":53.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HYH210BL-1.webp?v=1778123054","url":"https:\/\/batteryweb.com\/products\/honeywell-ih21-rfid-replacement-battery-37v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
