It fits the G2 bodypack transmitter, the EK1038 receiver, and the 2015FM unit. The BA2015 cell slot and connector match the original pack directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eG2, EK1038, and 2015FM compatibility:\u003c\/strong\u003e\n    All three units share the same 2.4V Ni-MH cell format, identical footprint, and the same two-pin contact arrangement. Swapping between these models does not require any adapter or firmware change.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack in a G2 bodypack and cycled it through the base station charge circuit. The cell accepted a full charge without thermal event, and the base station cleared its charging indicator cleanly at end of cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge in the base station:\u003c\/strong\u003e\n    Place the unit in the base station and let it complete one uninterrupted full charge before use. The G2 base needs to log the new cell before its talk-time indicator reads correctly — cutting that first charge short leaves the display permanently off by a wide margin.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing a charging error with the new pack fitted\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe G2 base station monitors cell voltage at the start of each charge cycle. A new Ni-MH pack sitting at storage voltage — typically 2.0–2.1V — can register below the base's detection threshold, triggering an error flag before charging even starts. This is not a fault with the battery. Remove the unit, wait 10 seconds, and reseat it firmly so both contact pins make clean contact. If the error persists, check that the contacts on the bodypack are free of oxidation before reseating.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHeadset cuts out mid-transmission on a fresh battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells deliver a flat discharge curve, but combined DECT radio draw and audio amplifier load in the G2 bodypack creates brief current spikes that a partially conditioned cell handles poorly. The result is a momentary voltage dip that trips the low-voltage cutoff — the unit drops the RF link and cuts out. This typically clears after three to five full charge-discharge cycles as the cell reaches its rated 1500mAh capacity. Cycle the pack fully three times and retest before assuming a fault.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428159946842,"sku":"BWCS-SBA015SL-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428159979610,"sku":"BWCS-SBA015SL-2","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428160012378,"sku":"BWCS-SBA015SL-3","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SBA015SL-1.webp?v=1779934278","url":"https:\/\/batteryweb.com\/products\/sennheiser-g2-replacement-battery-24v-1500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
