The pack measures 32.10 × 16.80 × 4.70mm — physically identical to the OEM cell. Voltage and capacity match OEM spec exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAirLine 88, AirLine 99M, and SWAH2 AirLine Micro compatibility:\u003c\/strong\u003e\n    All three bodypacks share the same transmitter circuit board, connector pinout, and BMS handshake protocol — one cell SKU covers the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell in an AirLine 88 bodypack and confirmed the BMS completed its handshake on the first insertion. The transmitter powered on immediately with no low-battery flag and held a stable 3.7V output rail across the RF and audio draw cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge in the transmitter — not standalone:\u003c\/strong\u003e\n    On first use, seat the battery in the bodypack and charge it via the AirLine charging dock for a complete cycle before going live. The transmitter's BMS logs the new cell during this cycle and begins calibrating the battery indicator — skipping it leaves the gauge inaccurate for the first several uses.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the AirLine 88 bodypack cuts out mid-transmission on a new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh Li-polymer cell shipped at storage voltage — typically around 3.6–3.65V — has not yet gone through a conditioning cycle. Under the combined draw of the RF transmitter and audio circuit, a cell at storage voltage can sag below the BMS cutoff threshold briefly, triggering a shutdown. This is not a fault in the battery or the bodypack. One full charge-discharge cycle through the charging dock brings the cell to its rated capacity and stabilises the voltage under load. After that first cycle, mid-transmission cutouts caused by voltage sag stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time noticeably shorter than rated for the first few uses\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-polymer cells do not deliver full rated capacity on cycle one — 230mAh is the stable capacity reached after three to five full charge-discharge cycles. Early cycles typically deliver 85–90% of that figure, which is normal electrochemical behaviour, not a defective cell. Each full cycle through the AirLine charging dock builds usable capacity incrementally. By cycle five, runtime should stabilise at the rated level — if it does not, check that the dock contacts are clean and the bodypack is seating fully before writing off the cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428095492186,"sku":"BWCS-SAL990SL-1","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428095524954,"sku":"BWCS-SAL990SL-2","price":42.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428095557722,"sku":"BWCS-SAL990SL-3","price":47.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SAL990SL-1.webp?v=1779934086","url":"https:\/\/batteryweb.com\/products\/samson-airline-88-replacement-battery-37v-230mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
