It replaces OEM part number WIZA16 when the original cell has degraded or failed. Voltage and capacity match factory specification for these three models.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWizard 100 \/ 110 \/ 200 platform fitment:\u003c\/strong\u003e\n    All three Wizard variants share the same battery bay dimensions, 3.7V nominal rail, and WIZA16 connector pinout. The BMS handshake protocol is identical across the series, so one cell fits all three without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on a Wizard 100 unit and confirmed the BMS accepted the new cell on first insertion — charge current ramped normally from trickle to CC phase without a fault flag.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    After installing this cell, run one complete discharge down to automatic shutdown, then charge uninterrupted to 100% before normal use. The Wizard's fuel gauge IC maps its percentage readings against a discharge curve it learns on that first full cycle — skipping it leaves the coulomb counter working against the old cell's curve.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Wizard 100 shuts down suddenly at 20–30% battery remaining\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh Li-ion cell has a steeper voltage-discharge curve than a worn one. When the Wizard's modem fires a high-current transmit burst or the screen backlight peaks, the new cell's voltage momentarily dips below the BMS undervoltage threshold — even if the fuel gauge still shows 25%. The phone reads that voltage drop as a fault and cuts power immediately. This behaviour typically settles after two or three full charge-discharge cycles as the BMS learns the new cell's internal resistance profile. If shutdowns continue past cycle three, check that the battery contacts in the bay are clean and making full contact.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Wizard stores a learned discharge curve for the old cell in its fuel gauge IC. When a new cell goes in, the IC tries to map current charge state against that stale curve — the mismatch causes percentage readings to jump 10–15 points between screen refreshes. The fix is a single uninterrupted full cycle: drain the phone to auto-shutdown, then charge straight to 100% without interruption. After that cycle the fuel gauge IC overwrites the old curve data and percentage reporting stabilises to within ±3%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405152747610,"sku":"BWCS-CL8125XL-1","price":26.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43405152780378,"sku":"BWCS-CL8125XL-2","price":30.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43405152813146,"sku":"BWCS-CL8125XL-3","price":33.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CL8125XL-big.webp?v=1779370297","url":"https:\/\/batteryweb.com\/products\/htc-wizard-100-replacement-battery-37v-2350mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
