It fits the same physical footprint at 53.20 × 34.00 × 5.70mm and connects to the same charge circuit the phone already uses. Capacity is 4.44Wh — matching the original specification from Tiptel.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eErgophone 6010–6021 series fit:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, connector pinout, and 3.7V charge rail. The BMS on each variant communicates with the same fuel gauge IC, so the same cell works across all units without hardware modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full discharge and charge sequences on the Ergophone platform. The BMS accepted the new cell without tripping protection flags, and the charge IC engaged at the correct constant-current threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    After installation, run one complete discharge down to automatic cutoff, then charge uninterrupted to 100% before regular use. The Ergophone's fuel gauge IC maps its coulomb counter to the new cell's discharge curve during this first cycle — skipping it causes the percentage display to report inaccurate figures from the first day.\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 the Ergophone after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh Li-ion cell has a steeper voltage cliff than a broken-in one. The Ergophone's modem and screen together pull enough current during active use to drop cell voltage below the BMS cutoff threshold — even when the fuel gauge still reads 25%. This happens most often during calls or screen-on navigation because those loads spike current draw sharply. After one full recalibration cycle, the fuel gauge IC learns where the actual voltage cliff sits and adjusts the reported percentage to match.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone not powering on after the battery has sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells that discharge below approximately 2.5V in storage trigger a BMS lockout — the protection circuit opens to prevent cell damage, and the phone will not respond to a normal power button press. Connect the Ergophone to a charger and leave it for 15–20 minutes without pressing anything. The charge IC trickle-charges the cell at low current until voltage clears the BMS reactivation threshold, typically around 2.9–3.0V, at which point the BMS closes and normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391811125338,"sku":"BWCS-PTU110SL-1","price":16.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391811158106,"sku":"BWCS-PTU110SL-2","price":17.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391811190874,"sku":"BWCS-PTU110SL-3","price":18.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PTU110SL-1.webp?v=1779142239","url":"https:\/\/batteryweb.com\/products\/tiptel-ergophone-6010-replacement-battery-37v-1200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
