It matches OEM part numbers 41B025AK00201 and 41B025AK00501. Voltage, chemistry, and connector type are matched to the original pack specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDual OEM part number coverage:\u003c\/strong\u003e\n    The 41B025AK00201 and 41B025AK00501 designations cover the same voltage rail and BMS handshake profile. Both share the same connector footprint and cell configuration, so one replacement pack covers both OEM references without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full charge and load discharge on bench equipment. The BMS held the 10.8V nominal rail cleanly under transmit-level draw, with no overcurrent trip or premature cutoff detected during the cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eContact strip prep on first dock insertion:\u003c\/strong\u003e\n    If the charger shows a fault LED on first seating, remove the pack and wipe the metal contact strip with a dry cloth. Ma-Com-Ericsson dock chargers require a clean contact surface to complete the BMS handshake before the charge cycle begins — reseating after wiping clears this in most cases.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the radio cuts out mid-transmission on a freshly inserted pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells ship at storage voltage — typically 1.0–1.1V per cell, which puts a 10.8V nine-cell pack around 9.0–9.9V on arrival. When PTT is pressed, transmit current draw spikes sharply. If the pack voltage is already below the BMS transmit-threshold, the radio's protection circuit trips and drops the output before the transmission completes. This is not a fault in the replacement pack — it is normal BMS behaviour at storage state of charge. Run one full charge cycle before first transmit use, and the cutout will not recur.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after a full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eMa-Com-Ericsson portables read battery level by measuring terminal voltage against fixed thresholds — there is no fuel gauge chip involved. A new Ni-MH pack may not stabilise at peak voltage until after the first full charge-and-rest cycle. If the indicator shows one bar fewer than expected immediately after charging, let the pack rest in the radio for 15–20 minutes off-charger. Terminal voltage will settle, and the bar reading will correct itself at or above the expected threshold for the charge level.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426320711770,"sku":"BWCS-UPX500TW-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426320744538,"sku":"BWCS-UPX500TW-2","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426320777306,"sku":"BWCS-UPX500TW-3","price":55.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-UPX500TW-1.webp?v=1779930681","url":"https:\/\/batteryweb.com\/products\/ma-com-ericsson-replacement-battery-108v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
