It fits the same footprint as the factory pack — 53.23 x 40.76 x 8.60mm — and uses the same connector and BMS handshake the scanner expects. If your H-19 is shutting down mid-shift or no longer holding a charge, this cell replaces it directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eH-19 and H-16 platform compatibility:\u003c\/strong\u003e\n    The H-19, H-19a, H-19d, and H-16 all share the same 3.7V battery bay and BMS communication protocol. Swapping between these models works because the voltage rail, connector pinout, and charge termination logic are identical across the family.\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 an H-19 unit. The BMS accepted charge termination cleanly, reported state-of-charge correctly to the scanner's firmware, and held voltage stable under repeated scan trigger events.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation for pick-and-pack use:\u003c\/strong\u003e\n    Before running this battery on the warehouse floor, seat it in the cradle for a complete charge cycle. The scan trigger inrush current is highest when the cell is near minimum — a fully charged cell prevents false BMS trips during the first shift's rapid scan bursts.\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 on a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eCharging cradles for the H-19 use contact-based charging, which makes them sensitive to contact resistance. A new pack with oxidation or residue on the gold contacts can cause the cradle to flag a fault rather than begin charging. Wipe the contacts on both the battery and the cradle dock with a dry lint-free cloth, then reseat the pack firmly. If the error clears, the cell was not making a solid electrical connection — not a fault with the battery chemistry itself.\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 H-19 draws current from the same cell for both the wireless radio and the scan trigger simultaneously. During rapid burst scanning, the combined inrush from the imager and the radio transmitter can pull voltage down briefly. If the cell is partially discharged, that voltage sag crosses the BMS cutoff threshold and the radio drops connection before the scanner fully shuts down. Charge the battery to 4.2V before a high-frequency scanning shift to keep the voltage headroom above the cutoff floor.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324954017882,"sku":"BWCS-OPH190BL-1","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324954050650,"sku":"BWCS-OPH190BL-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324954083418,"sku":"BWCS-OPH190BL-3","price":36.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OPH190BL_1.webp?v=1778123452","url":"https:\/\/batteryweb.com\/products\/opticon-h-19-replacement-battery-37v-900mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
