It fits the same battery bay and uses the same connector as the original pack. Rated at 15.2Wh, it supports full-shift scanning in retail, logistics, and warehouse operations.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCT40 and CT40XP compatibility:\u003c\/strong\u003e\n    Both devices share the same battery bay dimensions, contact layout, and BMS handshake protocol. A single cell covers both platforms — no adapter or firmware change needed.\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 a CT40 unit. The BMS balanced correctly, hit full charge cutoff at the expected voltage, and showed no false low-battery flags during simulated scan-burst draws.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation for pick-and-pack:\u003c\/strong\u003e\n    Place the scanner in its cradle for a complete charge cycle before using the new pack on the floor. 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.\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\"\u003eHoneywell CT40 cradles communicate with the battery BMS over the dock contacts. If those contacts carry oxidation or debris from the old pack, the cradle may flag a charging fault on a pack that is otherwise fine. Wipe the battery contacts and the cradle dock pins with a dry cloth, then reseat the device firmly. If the error clears, the fault was contact resistance — not a faulty cell. If the error persists after cleaning and reseating, check that the cradle firmware recognises third-party OEM part numbers.\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 CT40 draws simultaneously from its barcode imager and its 802.11 radio during rapid scanning. Combined inrush can cause a brief voltage sag that the BMS reads as a low-cell event, triggering a radio reset to protect the cell. This typically happens when the battery is below 20% charge and scan bursts run at high frequency. Charge the pack above 50% before high-throughput sessions, and the combined draw stays within the BMS's trip threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324733653082,"sku":"BWCS-HYT500BL-1","price":31.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43324733685850,"sku":"BWCS-HYT500BL-2","price":34.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43324733718618,"sku":"BWCS-HYT500BL-3","price":38.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HYT500BL-1.webp?v=1778123056","url":"https:\/\/batteryweb.com\/products\/honeywell-ct40-replacement-battery-38v-4000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
