🔋 90-day warranty is the industry standard for replacement batteries. Batteries naturally lose capacity over time — this normal wear is not covered. Warranty applies to manufacturing defects only.

Bring your Alcatel T508N or TCL T508N back to reliable daily performance with this TLI029CA / TLI029CB 3000mAh replacement battery. These T508N models are basic feature phones or entry-level smartphones designed for calling, texting, and light app use — often used as backup phones, work devices, or first phones for seniors and children. The 3000mAh battery was a key feature for these devices, providing several days of standby time on a single charge. After years of use, the original battery has likely degraded significantly. This Li-ion Polymer replacement battery restores the full 3000mAh capacity, giving you back the long standby times and dependable daily power these phones were known for. Built with grade A cells and multi-layer safety protection against overcharge, over-discharge, and short circuits. CE, RoHS, and UN38.3 certified.
Why TLI029CA and TLI029CB Are the Same Battery — And Why That Matters for You: Alcatel and TCL used two different model numbers — TLI029CA and TLI029CB — for the exact same 3000mAh battery across different production batches or regional variants. This can be confusing for users trying to find a replacement. The good news: both codes refer to an identical battery with the same 3.85V rated voltage, 4.4V charge limit, physical dimensions, and connector type. If your original battery shows either TLI029CA or TLI029CB, this replacement is the correct match. The T508N series was designed for users who prioritize battery life and simplicity over advanced features. Common signs that your battery needs replacement include: the phone no longer lasting a full day on a single charge, needing to charge daily instead of every few days, the battery draining rapidly even when idle, or the phone shutting down with 20-30% charge remaining. Unlike modern smartphones, the T508N often has a removable back cover, making battery replacement significantly easier for DIY users.
Compatibility Note: Fits Alcatel T508N and TCL T508N only. Both TLI029CA and TLI029CB are correct for these models. Please confirm your battery model before ordering — either TLI029CA or TLI029CB printed on your original battery. This battery is NOT compatible with Alcatel 1 series, Alcatel 3 series, TCL 10/20/30 series, or other TCL/Alcatel models. The T508N is a specific entry-level device; using a battery from a different model may have incorrect connector orientation or voltage specifications.

Frequently Asked Questions

There is no functional difference between TLI029CA and TLI029CB batteries — they are two different model numbers for the exact same 3000mAh battery used in Alcatel T508N and TCL T508N phones. Alcatel and TCL used both codes across different production batches or regional variants. If your original battery shows TLI029CA or TLI029CB, this replacement is the correct match. For TLI029CA TLI029CB battery compatibility with Alcatel T508N, both model numbers refer to the same 3.85V Li-ion Polymer cell with identical dimensions, 4.4V charge limit, and small 2-pin connector. You do not need to match the specific code — either one is fine. Please check your original battery label before ordering to confirm your device uses one of these two codes. This battery is NOT compatible with phones that use different battery model numbers.

The TLI029CA 3000mAh battery for Alcatel T508N has a typical capacity of 3000mAh (11.55Wh) and a rated voltage of 3.85V, with a charge limit of 4.4V. This 3000mAh 3.85V Li-ion Polymer battery for TCL T508N delivers the original battery life that made these devices reliable for basic phone users. For Alcatel T508N battery life expectations, a fresh TLI029CA battery provides approximately: 5-7 days of standby time (phone idle with occasional checks), 8-10 hours of continuous talk time, 6-8 hours of web browsing or light app use, and 2-3 days of light mixed usage (calls, texts, occasional apps). The T508N's simple hardware and efficient processor help maximize battery life compared to smartphones. The battery supports standard 5V/1A or 5V/2A charging — a full charge from 0% takes approximately 2-2.5 hours. The phone does not support fast charging. If your original TLI029CB battery now drains faster or requires daily charging, this replacement battery will restore the long standby times the T508N was known for.

Yes, Alcatel T508N battery replacement is relatively easy because many T508N units have a removable back cover — a feature uncommon in modern phones. To replace Alcatel T508N battery TLI029CA: 1) Power off the device. 2) Remove the back cover by prying from the notch. 3) Remove the old battery — it typically lifts out without tools. 4) Disconnect the old battery's small 2-pin connector by pulling the plug (not the wires). 5) Connect the new battery — the connector is keyed and only fits one way. 6) Place the new battery in the compartment and snap the back cover back on. No heat gun, no adhesive, no special tools required. If your T508N has a sealed design (some variants), professional installation is recommended. For TCL T508N battery health maintenance: 1) Use a standard 5V/1A or 5V/2A charger — avoid fast chargers that may confuse the charging circuit. 2) Keep battery level between 20% and 80% for daily use to maximize lifespan. 3) Avoid exposing the phone to high temperatures (above 40°C / 104°F). 4) For long-term storage (over 2 months), keep the battery at approximately 60% charge. 5) For Alcatel T508N battery care tips, perform a full calibration cycle after installation: drain the phone until it auto-shuts off, then charge uninterrupted to 100%. Stop using immediately if the battery shows any swelling.
