It fits the compact housing of the Inspire 500 and restores power to the audio and wireless transmission circuits. Dimensions are 31.60 x 12.10 x 5.00mm — measure your existing cell before fitting.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eInspire 500 fit:\u003c\/strong\u003e The Inspire 500 runs audio decoding and the wireless radio from a single 3.7V cell. The GSP051230 footprint is specific to this earbud housing — the connector position and cell profile are matched to the original board layout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e We ran this cell through charge and discharge cycles on the Inspire 500 board. The BMS accepted the cell without error flags, and the protection circuit responded correctly to both charge termination and low-voltage cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after fitting:\u003c\/strong\u003e Place the Inspire 500 in its charging cradle and allow a full uninterrupted charge cycle before use. The onboard fuel gauge needs a complete cycle to calibrate against the new cell — skipping this gives inaccurate charge indicators from the start.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Inspire 500 cuts out mid-workout on a new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Inspire 500 draws from one small cell to power both audio decoding and the wireless radio simultaneously. Under combined load — particularly during high-tempo audio with strong signal demand — voltage briefly sags below the BMS cutoff threshold. A new cell that hasn't completed its first full conditioning cycle has slightly higher internal resistance, which makes that sag more pronounced. After three to five full charge-discharge cycles, internal resistance drops and the cutoff events stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharging cradle shows full but earbuds cut off after short use\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the replacement cell arrives at storage voltage — typically around 3.6V — and the cradle reads that as near-full rather than running a complete charge cycle. The fuel gauge then reports 100% against a cell that is not fully topped up. Run one full charge from flat to termination in the cradle. After that cycle, the gauge resets its reference and the reported charge level will match actual capacity.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428097720410,"sku":"BWCS-JBP500SL-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428097753178,"sku":"BWCS-JBP500SL-2","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428097785946,"sku":"BWCS-JBP500SL-3","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-JBP500SL-1.webp?v=1779934061","url":"https:\/\/batteryweb.com\/products\/jbl-inspire-500-replacement-battery-37v-110mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
