It replaces OEM part TLp030JC or CAC3000034CC. Use the Capacity field value of 11.36Wh as your reference — that is what this cell delivers under real load.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCross-model fit — TIM XL 2018, A3A XL 4G, OT-5099T and related variants:\u003c\/strong\u003e\n    These models share the same battery footprint, connector pinout, and BMS handshake protocol. The 76.70 × 66.20 × 3.50mm cell dimensions and 3.85V nominal rail are consistent across all listed variants, so one SKU 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 cycled this cell through charge and discharge on a compatible unit. The BMS accepted the cell without fault codes, charge termination triggered correctly at 4.35V, and low-voltage cutoff engaged at the expected threshold under screen-on load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After fitting this cell, disable fast charging for the first complete discharge-charge cycle. The fuel gauge IC was calibrated to your original cell's discharge curve. One slow cycle lets it remap to the new cell before fast charge current is applied to an uncalibrated state.\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 TIM XL 2018 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC still holds the discharge curve of the original, degraded cell. When the new cell's actual voltage under modem or screen load drops faster than the IC expects, the system reads a safe percentage right up until the voltage cliff hits. The phone cuts off because the hardware voltage floor is reached before the software counter reaches zero. One full slow discharge-charge cycle resets the coulomb counter and maps the new cell curve correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB charging not recognised on first plug-in after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA freshly installed Li-Polymer cell with no charge history can sit below the USB detection threshold if it discharged in storage. The charge IC on this platform requires the cell to be above approximately 3.0V before it negotiates a USB-PD or standard 5V contract. If the phone shows nothing when plugged in, leave the cable connected for 15–20 minutes — the IC trickle-charges the cell in recovery mode before switching to normal charging. If the cell was stored at or near 0% for an extended period, start with a 5V\/1A wall adapter rather than a fast charger to avoid tripping BMS lockout.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391998787674,"sku":"BWCS-OTX908SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391998820442,"sku":"BWCS-OTX908SL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391998853210,"sku":"BWCS-OTX908SL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OTX908SL-1.webp?v=1779142874","url":"https:\/\/batteryweb.com\/products\/alcatel-tim-xl-2018-replacement-battery-385v-2950mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
