🔋 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 Blade A6 Max or Blade A3 with this Li3939t44p8h856743 4000mAh replacement battery. The Blade A6 Max (model A0605) features a 5.5-inch HD display and a large 4000mAh battery designed for extended usage. The Blade A3 (model A0616), released in 2017, was built around a 3900mAh battery with dual front-facing cameras for selfies. After 7-8 years of use, the original battery has likely degraded significantly — losing capacity, draining faster, or shutting down unexpectedly. This Li-ion Polymer battery restores the full 4000mAh typical capacity, bringing back the reliable 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.
Two Devices, One Battery Solution: The ZTE Blade A6 Max and Blade A3 share the same battery design despite being different models. The Blade A3 was positioned as a long-battery-life device, with its 3900mAh capacity being a key selling point. The Blade A6 Max continues this focus with a 4000mAh battery. Both devices use the same Li3939t44p8h856743 battery, making this replacement compatible across models. Common signs of battery failure include: the phone needing multiple charges per day, shutting down at 20-30% battery, slower charging than originally, or the back cover showing signs of swelling. Unlike many modern smartphones, the Blade A6 Max and A3 feature removable back covers, making the battery replacement relatively straightforward. A fresh battery restores the original standby time and talk time, giving these classic devices a new lease on life instead of purchasing a new phone.
Compatibility Note: Fits ZTE Blade A6 Max (A0605), ZTE Blade A3 (A0616), and ZTE Blade Max 2s. This battery is NOT compatible with ZTE Blade A3 2019, ZTE Blade A7, or other ZTE models. Always check your original battery model — Li3939t44p8h856743 is printed on the original battery.
