It slots into the same footprint as the original at 53.20 × 34.00 × 6.20mm. If your unit cuts out early or won't hold a charge, this is the cell to swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMicroCom XR and XR900 compatibility:\u003c\/strong\u003e\n    Both the MicroCom XR and XR900 share the same battery bay dimensions, connector pinout, and 3.7V nominal rail — one cell fits both variants without modification.\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 discharge on the MicroCom XR platform. The BMS accepted full charge without fault flags and held voltage steady through audio playback draw at the amplifier rail.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMonthly discharge cycle for MicroCom XR users:\u003c\/strong\u003e\n    Let the battery run below 20% at least once a month before plugging in. The MicroCom XR spends most of its life topped off on a desk charger — constant shallow cycling causes fuel gauge drift, so the indicator reads full while actual capacity has quietly dropped.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAudio distortion before the battery indicator reaches empty on the MicroCom XR\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eAs a Li-Polymer cell ages, its internal resistance rises. Under the combined draw of the amplifier and Bluetooth radio, voltage sags faster than the fuel gauge tracks. The amplifier rail drops below the threshold needed to drive clean output, and you hear clipping or crackle while the indicator still shows charge remaining. Swapping in a fresh 900mAh cell with lower internal resistance restores clean headroom to the amp rail.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMicroCom XR won't wake from USB after sitting discharged\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the unit sits unused for several weeks with no charge, the cell can drop below the USB charge controller's minimum acceptance voltage — typically around 2.5V for Li-Polymer. At that point the controller sees an out-of-range cell and refuses to start a charge cycle. Connect to a USB port and hold the power button for 10–15 seconds to trigger a low-current pre-charge handshake. If the device still shows no charging activity after two minutes, the cell has likely dropped below recovery threshold and replacement is the correct fix.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416182194266,"sku":"BWCS-PMR900SL-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416182227034,"sku":"BWCS-PMR900SL-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416182259802,"sku":"BWCS-PMR900SL-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PMR900SL-1.webp?v=1779760648","url":"https:\/\/batteryweb.com\/products\/pliant-microcom-xr-replacement-battery-37v-900mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
