It fits the CDM8992, CDM8992VM, and CDM-8992 variants — all share the same battery bay and connector. Swap it in when the original cell no longer holds a usable charge or fails to power on.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHotShot 8992 series fit:\u003c\/strong\u003e\n    The CDM8992, CDM8992VM, and CDM-8992 all draw from the same voltage rail and use the same physical connector as the standard HotShot 8992. One cell covers all four 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 HotShot platform. The BMS accepted the cell on first insertion and the charge IC brought it to full voltage without flags or interruptions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    After installing this cell, run one full discharge down to automatic shutdown, then charge uninterrupted to 100% before normal use. The fuel gauge IC on the HotShot was calibrated to the old cell's discharge curve — one complete cycle resets it to the new cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on a replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC still references the discharge curve of the old, degraded cell. The new cell has a steeper voltage cliff under modem and screen load than the gauge expects. When current draw spikes — during a call or screen wake — terminal voltage drops faster than the gauge predicts, triggering a low-voltage cutoff. One full discharge-to-shutdown cycle followed by a complete charge corrects the gauge's reference curve and eliminates the false cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone reports incorrect percentage after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe HotShot's fuel gauge IC uses a coulomb counter tied to the previous cell's capacity profile. A fresh 900mAh cell does not match that stored profile, so the gauge reads high or low by a wide margin. The phone may show 60% on a nearly full cell or drop suddenly without warning. Force a full recalibration: drain the phone to shutdown, then charge continuously to 100% with the screen off — the gauge rewrites its reference point at both endpoints.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405013352538,"sku":"BWCS-PT8992SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405013385306,"sku":"BWCS-PT8992SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405013418074,"sku":"BWCS-PT8992SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PT8992SL-1.webp?v=1779369819","url":"https:\/\/batteryweb.com\/products\/pantech-hotshot-8992-replacement-battery-37v-900mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
