🔋 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.

Restore the full power of your Vivo V50E with this BA78 5600mAh replacement battery. The Vivo V50E is a feature-rich mid-range smartphone designed for users who prioritize long battery life and reliable daily performance. With its large display and efficient processor, the V50E is built for entertainment, productivity, and extended usage.

Designed for Extended Usage and Fast Charging: The Vivo V50E is built for users who need reliable power throughout the day. The 5600mAh battery originally provided approximately a full day of heavy use and multiple days of light use. 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 the device without the cost of a new phone. The BA78 battery is fully compatible with the phone’s fast charging technology, ensuring quick and efficient power delivery when you need it.
Compatibility Note: Fits Vivo V50E (V2440) only. Please confirm your battery model before ordering — BA78 is printed on your original battery. This battery is NOT compatible with Vivo V50, V50 Pro, V50 Lite, Y series, or other Vivo models. The V2440 is the model number for the V50E; using a different battery model may cause charging issues or incorrect battery reporting.
