At 54.00 × 34.20 × 5.70mm, it matches the OEM form factor for direct installation. Capacity is 4.07Wh — identical to the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePWM-10T, QDX-6000, and Wireless Soundstation PWM-10 compatibility:\u003c\/strong\u003e\n    All three units share the same battery bay dimensions, 3.7V nominal cell voltage, and connector orientation — which is why they run the same OEM part number (2200-32400-001). The BMS handshake on each platform monitors cell voltage at the same cutoff threshold.\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 load discharge on the PWM-10T transmitter body. The BMS held cutoff at the expected low-voltage threshold and the charge circuit accepted the cell without fault codes or interruption.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eWireless microphone transmitter storage tip:\u003c\/strong\u003e\n    If the transmitter sits unused between events for several weeks, power it on and run the battery down to roughly 20% before storing — leaving it at full charge in a warm equipment bag accelerates cell degradation faster than regular use does.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the PWM-10T cuts out mid-transmission even on a full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe PWM-10T transmitter draws a brief current spike each time the RF output ramps up. On a degraded cell, internal resistance rises enough that this spike causes a momentary voltage sag past the BMS low-voltage trip point — the unit cuts out even though the fuel gauge still reads high. The issue isn't capacity; it's the cell's ability to deliver current without dropping voltage. A fresh 1100mAh cell with low internal resistance handles the RF spike without tripping the BMS. If the transmitter is cutting out mid-session, check cell resistance first — not remaining capacity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePWM-10T showing a solid charge indicator but powering off after light use\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a fuel gauge drift symptom, not a hardware fault. It happens when the transmitter is regularly topped off from 60–80% without ever being discharged below 20% — the battery management IC loses calibration and reports inaccurate state of charge. The fix is a full conditioning cycle: run the transmitter down until it shuts off from depletion, then charge it uninterrupted to 100%. After one full cycle, the fuel gauge recalibrates and the charge indicator reflects actual cell voltage again.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416224366682,"sku":"BWCS-PST600SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416224399450,"sku":"BWCS-PST600SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416224432218,"sku":"BWCS-PST600SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PST600SL-1.webp?v=1779761021","url":"https:\/\/batteryweb.com\/products\/polycom-pwm-10t-replacement-battery-37v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
