It fits the 39a-Ex directly using OEM part number 233488-001. Over time, Li-Polymer cells lose charge-holding capacity through normal cycling — this replacement restores full power to the device.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e39a-Ex platform fit:\u003c\/strong\u003e\n    The 39a-Ex uses a 3.7V Li-Polymer cell with a BMS handshake tied to OEM part 233488-001. The connector pinout and voltage rail match the original, so the device firmware recognises the replacement without any error state.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the 39a-Ex platform. The BMS accepted full charge to 4.2V, held the low-voltage cutoff correctly, and reported charge state accurately to the OS throughout the test.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePre-removal sync requirement:\u003c\/strong\u003e\n    Perform a full ActiveSync or WMDC data sync to the host PC before pulling the battery. The 39a-Ex holds open application state and unsaved data in SRAM, which is powered entirely by the main battery — any power break without syncing first can result in data loss.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the 39a-Ex won't boot after a new battery is installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA freshly shipped Li-Polymer cell typically arrives at storage charge — around 3.6V to 3.8V. The 39a-Ex boot sequence draws a short current spike that can trip the BMS if the cell voltage is below the device's minimum boot threshold. The unit appears dead but is not faulty. Charge the new battery for at least 30 minutes before attempting the first boot.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery life shorter than expected during active warehouse scanning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 39a-Ex in active scanning use draws significantly more current than in standby — the barcode scanner LED and any active wireless radio (Wi-Fi or Bluetooth) together can triple the average current draw versus idle. A 1700mAh cell that looks adequate on paper will deplete faster than expected under continuous scan cycles. If runtime drops sharply, check whether the wireless radio is left on between scans, as disabling it when not actively syncing reduces draw noticeably. Monitor battery percentage after a standard shift to establish a real-world baseline.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415953178714,"sku":"BWCS-IP3800SL-1","price":29.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43415953211482,"sku":"BWCS-IP3800SL-2","price":34.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43415953244250,"sku":"BWCS-IP3800SL-3","price":37.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IP3800SL-1.webp?v=1779758425","url":"https:\/\/batteryweb.com\/products\/ecom-39a-ex-replacement-battery-37v-1700mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
