🔋 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.

Revive your ZTE smartphone with this Li3939T44P8H906450 5000mAh replacement battery. This battery is compatible with four popular ZTE A-series models — A52 (4G), A72 (4G), A73 (5G), and A53 PRO. These devices were designed for users who value long battery life and reliable daily performance, with the 5000mAh capacity providing exceptional endurance for calls, messaging, web browsing, and media consumption. After years of use, the original battery capacity has likely degraded significantly. This Li-ion Polymer battery restores the full 5000mAh capacity, bringing back the all-day battery life these devices 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.
Designed for Extended Usage: The 5000mAh battery was a standout feature of the ZTE A-series, providing approximately 1.5 to 2 days of moderate use on a single charge. After years of charging cycles, the original battery’s capacity drops significantly. Common symptoms include: the device requiring multiple charges per day, unexpected shutdowns at 15-25% battery remaining, slower charging than when new, or visible battery swelling. This replacement restores the original battery life, extending the useful life of your device. The Li3939T44P8H906450 battery is fully compatible with the original charging specifications of all four models, allowing for reliable charging performance. A fresh battery brings back the dependable, long-lasting experience these ZTE devices were designed to deliver.
Compatibility Note: Fits ZTE A52 (4G), ZTE A72 (4G), ZTE A73 (5G), and ZTE A53 PRO. Please confirm your battery model before ordering — Li3939T44P8H906450 is printed on your original battery. This battery is NOT compatible with ZTE Blade series, ZTE Axon series, ZTE Nubia series, or other ZTE models. The A52, A72, A73, and A53 PRO share the same battery design; using a different battery model may cause charging issues or incorrect battery reporting.

Replacing the battery in ZTE A52, A72, A73, or A53 PRO requires careful disassembly as these devices have sealed designs. For ZTE A73 battery replacement guide: 1) Power off the device completely. 2) Heat the back cover to soften adhesive using a heat gun or hair dryer (no more than 70°C). 3) Carefully pry open the back cover using a plastic spudger — avoid cracking the cover or damaging internal components. 4) Locate the Li3939T44P8H906450 battery and disconnect the small 2-pin connector by pulling the plug (not the wires). 5) Remove the old battery (lightly adhered). 6) Connect the new battery — the connector is keyed and only fits one way. 7) Place the new battery in the compartment and reseal the device. For ZTE A52 battery installation, similar steps apply. Third-party repair shops typically charge $20-35 for this service. For ZTE battery health maintenance: 1) Use only the original ZTE charger and cable for optimal charging. 2) Keep battery level between 20% and 80% for daily use to maximize lifespan. 3) Avoid exposing the device to high temperatures (above 40°C / 104°F), especially while charging. 4) For long-term storage (over 2 months), keep the battery at approximately 40-60% charge. 5) Perform a full calibration cycle after installation: drain the device until it auto-shuts off, then charge uninterrupted to 100% using the original charger. For ZTE A53 PRO battery care tips, stop using immediately if the battery shows any swelling.
