✅ Why Our Warranty Stands Out

Unlike marketplace sellers with short buyer protection windows, we handle claims directly — no automated disputes, no endless back-and-forth.

🔋 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 rugged Blackview smartphone with this 605872 4380mAh replacement battery. The Blackview BV9700 Pro is the world’s first MTK P70 rugged phone, featuring a 5.84-inch FHD+ IPS display, IP68/IP69K dust/water resistance, MIL-STD-810G certification, heart rate monitor, and VOC air quality detection. This Li-Polymer battery delivers the factory-rated 4380mAh capacity, supporting 18W Quick Charge and 10W wireless charging — providing up to 2-3 days of normal usage on a single charge. For reference, third‑party retailers sell this battery for approximately $26 to $31.
Built with Grade A Li-Polymer cells and multi-layer safety protection against overcharge, over-discharge, short circuit, and overcurrent. CE and RoHS certified for safe transport and use. Each cell is tested for correct capacity and safety requirements before installation.
Compatibility Note: Please power down your device and check your original battery label before ordering. This battery is compatible with Blackview BV9700 and BV9700 Pro. The battery is not user‑replaceable — professional installation is strongly recommended. The phone has IP68/IP69K water resistance — proper resealing with fresh adhesive is required to maintain this protection after replacement.
Battery Care Tips: Avoid full discharge — keep battery level above 20%. Do not expose to high temperatures or direct sunlight. New batteries require 3-5 full charge cycles to reach optimal capacity. For best 18W fast charging performance, use a certified Quick Charge 3.0 charger. If you don’t use the device for a long time, store it in a dry and cool place and charge it fully once every three months. If you notice swelling or overheating, stop use immediately.

Frequently Asked Questions

The 605872 battery for Blackview BV9700 is compatible with Blackview BV9700 and Blackview BV9700 Pro. The BV9700 Pro is the world's first MTK P70 rugged phone, featuring a 5.84-inch FHD+ IPS display, IP68/IP69K dust/water resistance, MIL-STD-810G military grade certification, heart rate monitor, and VOC air quality detection. This 4380mAh battery for Blackview BV9700 Pro is a direct replacement for the original battery. If your Blackview BV9700 battery replacement is needed because the phone drains quickly or won't hold a charge, this is the correct battery. Please verify your device model and check the battery model 605872 printed on your existing battery before purchasing.

The 605872 4380mAh 3.85V battery has a typical capacity of 4380mAh (16.86Wh) and a rated voltage of 3.85V. Charge limit voltage is 4.4V. It is a Li-Polymer battery built with Grade A cells and is CE and RoHS certified. The Blackview BV9700 Pro supports 18W Quick Charge via USB-C and 10W wireless charging — with 18W fast charging, the 4380mAh battery can be fully charged in approximately 2-2.5 hours using a QC3.0 charger.

Professional installation is strongly recommended for Blackview BV9700 battery replacement. The Blackview BV9700 and BV9700 Pro have rugged sealed designs with IP68/IP69K dust and water resistance ratings — IP68 means the phone can be submerged in up to 1.5 meters of water for 30 minutes, while IP69K provides protection against high-pressure, high-temperature water jets. The process to replace the battery requires heating to soften adhesive, careful prying to avoid damaging the display or waterproof seals, and proper resealing with fresh adhesive to maintain IP68/IP69K water resistance after replacement. Water resistance may be compromised if the phone is not properly resealed. If you choose DIY phone battery replacement, watch a full teardown tutorial before starting, use a heat gun at low temperature (no more than 70°C), use plastic tools to avoid damaging internal components, and never reuse a battery after removal. Third-party repair shops typically charge $15-30 for labor, and IP68/IP69K water resistance may not be fully guaranteed after non‑professional repair.
