It fits the PDT6100, PDT6140, PDT6142, and PDT6146 — mobile data terminals used in retail, warehouse, and asset-tracking environments. OEM part numbers covered include 21-41321-03, SM-6100M, 21-33061-01, 21-38678-03, and 21-39369-03.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePDT6100 series fit:\u003c\/strong\u003e The PDT6100, PDT6140, PDT6142, and PDT6146 all run the same 3.6V battery rail with an identical connector and BMS handshake.

The BMS held stable across the draw spikes, and cell voltage stayed within the expected Ni-MH discharge curve without premature cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift prep for pick-and-pack:\u003c\/strong\u003e Place the scanner in its cradle for a full charge cycle before the first shift. Scan trigger inrush is highest when the cell is near minimum, and a fully charged pack prevents false BMS trips during high-frequency scanning bursts on day one.\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\"\u003eNi-MH packs that sit in storage ship with low resting voltage. Some Symbol cradles interpret this as a fault condition rather than a deeply discharged cell. The dock checks pack voltage on contact, and if it reads below its threshold, it throws an error instead of initiating a charge cycle. Wipe the battery contact pads and cradle contacts with a dry cloth, reseat the pack firmly, and the cradle should recognise it correctly and begin charging.\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 PDT6100 series drives both the scan laser and the wireless radio simultaneously during active scanning. During a rapid burst, the combined inrush from the scan trigger and radio polling can spike the draw beyond what a degraded or partially charged cell can sustain. Voltage sags briefly, the radio drops its connection, and the scanner stalls mid-session. Ensure the pack is fully charged before a high-frequency scanning shift — a full cell handles the combined draw without the voltage sag that trips the radio.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324967780442,"sku":"BWCS-PDT6100BL-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324967813210,"sku":"BWCS-PDT6100BL-2","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324967845978,"sku":"BWCS-PDT6100BL-3","price":37.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PDT6100BL-1.webp?v=1778123452","url":"https:\/\/batteryweb.com\/products\/symbol-pdt6100-replacement-battery-36v-1800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
