It fits the EG-340 directly and replaces OEM part numbers BI-1500 and BAT-BI-500. Dimensions are 53.62 × 36.46 × 9.50mm — measure your original pack if you are unsure before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEG-340 fit:\u003c\/strong\u003e The EG-340 runs a single-cell 3.7V Li-ion platform with a BMS that monitors cell voltage and temperature during scan trigger events. This pack matches the connector pinout and communicates correctly with the scanner's charge management circuit.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e We cycled this pack through repeated scan-trigger inrush events and wireless polling loads. The BMS held cutoff thresholds within spec and the scanner did not drop connection during burst-scan sequences.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation:\u003c\/strong\u003e After installing, seat the scanner in its charging cradle for a full charge cycle before use. Scan trigger inrush is highest when the cell is near minimum voltage — starting a pick-and-pack shift on a partially charged new cell can cause the BMS to trip early and interrupt operation.\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\"\u003eEG-340 charging cradles use dock contacts that oxidise over time. When a new pack is seated, higher contact resistance can cause the dock to report a charging fault even though the pack itself is fine. The cradle's charge controller reads the resistance across the contacts as an abnormal condition and halts the charge cycle. Wipe the gold contacts on both the battery and the cradle with a dry cloth, reseat firmly, and the charging indicator should clear within 30 seconds.\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 fast barcode scanning, the EG-340 draws simultaneously from the imager and the wireless radio. This combined inrush pulls the cell voltage down sharply for a fraction of a second. If the cell voltage dips below approximately 3.2V during that spike, the BMS may cut output and the radio stack drops its connection to the host. Letting the pack charge fully before a high-frequency scanning session keeps the cell voltage headroom above the BMS threshold and prevents mid-shift disconnects.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324715204698,"sku":"BWCS-BUP340BL-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324715237466,"sku":"BWCS-BUP340BL-2","price":44.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324715270234,"sku":"BWCS-BUP340BL-3","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BUP340BL-1.webp?v=1778122618","url":"https:\/\/batteryweb.com\/products\/bluebird-eg-340-replacement-battery-37v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
