It replaces OEM part number TLp020EC. Fit this battery when the original cell no longer holds charge through a normal day of use.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOT-6044 and OT-6044D compatibility:\u003c\/strong\u003e\n    Both the standard and Dual SIM variants use the same 3.8V cell with identical connector pinout and BMS handshake — one battery covers both boards 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 OT-6044 board. The BMS accepted the charge IC handshake cleanly, and protection thresholds triggered correctly at both high-voltage cutoff and low-voltage floor.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging pushes current into an uncalibrated cell — skipping this step is the main cause of erratic percentage readings.\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 OT-6044 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the fuel gauge IC is calibrated to the old cell's discharge curve, it misjudges remaining capacity on the new cell. The OT-6044's modem and display draw combined current spikes that cause the new cell's voltage to drop below the BMS cutoff threshold — even though the reported percentage still shows charge remaining. The phone sees a voltage cliff and cuts power to protect the cell. One full discharge-to-shutdown followed by an uninterrupted charge to 100% forces the coulomb counter to reset its reference points against the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone won't power on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells self-discharge during storage, and if the TLp020EC cell drops below approximately 2.5V, the BMS enters lockout mode and blocks charge input to prevent thermal runaway on an over-discharged cell. The phone will show no response to the charge cable and will not boot. Connect the phone to a wall adapter — not a USB port — and leave it for 15–20 minutes without pressing the power button. The charge IC applies a trickle current that brings the cell above the BMS re-enable threshold, typically around 2.9V, after which normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392021692506,"sku":"BWCS-OTP604SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392021725274,"sku":"BWCS-OTP604SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392021758042,"sku":"BWCS-OTP604SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OTP604SL-1.webp?v=1779142963","url":"https:\/\/batteryweb.com\/products\/alcatel-one-touch-pop-up-replacement-battery-38v-1900mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
