Restore the reliable power of your SUGAR C12, BQ-6016L Mercury, or Wiko View 3 Pro with this 386786 4000mAh replacement battery. All three devices were released between 2018 and 2019, a period when 4000mAh batteries represented a significant capacity advantage over competing models in the same price segment.
The SUGAR C12 and BQ-6016L Mercury both launched with Android 8.1 Oreo, featuring 6.0-inch displays and 13MP dual-camera setups. What sets these devices apart is their large-capacity battery — the BQ-6016L Mercury actually supports OTG reverse charging, allowing you to use your phone as a power bank to charge other devices, a feature that remains useful today. The Wiko View 3 Pro, released in 2019, comes with a 6.3-inch FHD+ display, MediaTek Helio P60 processor, 4GB or 6GB of RAM, and up to 128GB of storage. According to official specifications, its 4000mAh battery delivers up to two full days of normal usage on a single charge, validated by Smartviser testing laboratory.
Fast Charging Support & Daily Performance: This 386786 Li-ion Polymer battery is engineered to meet original specifications and supports the fast charging protocols of all three compatible devices. For Wiko View 3 Pro users, official testing shows the 4000mAh capacity provides up to 2 days of autonomy — whether you’re streaming videos, browsing social media, or making calls throughout the day. For BQ-6016L Mercury owners, the battery enables the device’s OTG reverse charging feature (requires a USB OTG adapter), letting you charge another phone or connect a USB flash drive directly — a handy feature for travelers or emergency situations.
Built-in Multi-Layer Safety Protection: This replacement battery is manufactured with grade A cells to ensure true 4000mAh capacity and long-lasting cycle life. It features multi-layer safety protection against overcharge, over-discharge, short circuits, and temperature extremes. CE, RoHS, and UN38.3 certified for safety compliance, it provides a secure and reliable power source for your daily needs. Professional installation is recommended for all three models as they have non-removable battery designs with sealed backs that require heating to soften adhesive.
Compatibility Note: Fits SUGAR C12, BQ-6016L Mercury, Wiko View 3 Pro (W-P611), Wiko Y80, and Wiko View 4 Lite. Please confirm your phone model before ordering (check in Settings > About Phone). If your device’s original battery drains quickly, shuts down unexpectedly, or exhibits swelling, this 386786 replacement battery is the correct solution.
Battery Care Tips for Extended Lifespan: To maximize the lifespan of your new battery, we recommend avoiding full discharges whenever possible — lithium batteries experience the least stress when kept between 20% and 80% charge. For best results, use the original charger that came with your device. If you notice swelling, overheating during normal use, or a sudden drop in runtime, stop using the battery immediately and consult a professional. New batteries typically require 3-5 full charge-discharge cycles to reach optimal performance calibration.
