It replaces OEM part numbers TLp041C2 and TLp041CC. If your tablet drains faster than it used to or won't hold a charge at all, this is the correct cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePOP 8 and Trek HD platform fit:\u003c\/strong\u003e\n    These tablets share the same 3.8V battery bay, connector pinout, and BMS handshake protocol across the P320A and OT-9020A variants. One SKU covers the full range.\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 POP 8 platform. The BMS accepted the new cell without fault codes, and charge termination triggered correctly at full capacity.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge reset after installation:\u003c\/strong\u003e\n    After fitting this battery, run the tablet down to automatic shutoff, then charge it uninterrupted to 100% without using the device. The fuel gauge IC calibrates against the new cell's actual charge curve during that first full cycle — skipping this step is why most users see jumpy percentage readings after a swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTablet shutting down at 15–25% remaining after battery replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC still holds the discharge curve from the old, degraded cell. When the new battery hits a voltage point the IC associates with near-empty on the old cell, it triggers a shutdown — even though actual capacity remains. The fix is a single full discharge-to-cutoff followed by an uninterrupted charge to 100%. After that cycle, the IC maps the new cell's voltage curve correctly and shutdowns stop occurring above 5%.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging unavailable on the POP 8 after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe charge IC negotiates charge rate during the first accepted cycle. If the tablet was powered off during installation or the first charge was interrupted, the IC may default to a slow trickle rate and not step up. Plug into the original Alcatel charger — not a generic USB port — and let the first charge complete without unplugging early. After one complete cycle, the charge IC re-negotiates and fast charge resumes. Confirm the charger outputs at least 5V\/2A to rule out the adapter as the limiting factor.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426024194138,"sku":"BWCS-ALP320SL-1","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426024226906,"sku":"BWCS-ALP320SL-2","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426024259674,"sku":"BWCS-ALP320SL-3","price":41.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ALP320SL-1.webp?v=1779930196","url":"https:\/\/batteryweb.com\/products\/alcatel-one-touch-pop-8-replacement-battery-38v-4050mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
