It fits the HTC Wizard 100, Wizard 110, and Wizard 200 — Windows Mobile smartphones from the mid-2000s that are still actively used and maintained. Drop it in when the original cell no longer holds a useful charge through a working day.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWizard 100, 110, and 200 compatibility:\u003c\/strong\u003e\n    All three models share the same battery bay dimensions, connector pinout, and 3.7V single-cell architecture, which is why one cell 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 through charge and discharge cycles on the Wizard platform and confirmed the BMS communicates correctly with the charge IC — no false full signals and no premature cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first install:\u003c\/strong\u003e\n    On first use, run one complete discharge down to automatic shutdown, then charge uninterrupted to 100%. This gives the fuel gauge IC a full reference curve against the new cell before Windows Mobile starts reporting accurate percentages.\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 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Wizard 100 uses a fuel gauge IC that tracks charge state against a learned discharge curve stored from the previous cell. A new cell has a different internal impedance and capacity, so the stored curve no longer maps correctly. The IC can read 40% remaining on a cell that is actually near depletion. One full discharge-to-shutdown and uninterrupted recharge resets the reference and brings percentage reporting back into alignment.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC is still calibrated to the old, degraded cell's voltage curve. The new cell has a steeper voltage cliff at low charge, and the device shuts down before the displayed percentage reaches zero. It is not a fault with the replacement cell. Run one full discharge cycle — letting the phone reach automatic shutdown — then charge to 100%, and the reported percentage will track actual remaining capacity correctly from that point.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405150617690,"sku":"BWCS-CL8125HL-1","price":31.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43405150650458,"sku":"BWCS-CL8125HL-2","price":36.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43405150683226,"sku":"BWCS-CL8125HL-3","price":40.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CL8125HL-big.webp?v=1779370297","url":"https:\/\/batteryweb.com\/products\/htc-wizard-100-replacement-battery-37v-2800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
