Revive the extreme endurance of your Oukitel WP30 Pro with this precision-engineered 5500mAh 7.74V replacement battery. Launched in late 2023, the WP30 Pro is widely recognized for its rugged durability and industry-leading 120W fast charging capability. This Li-ion Polymer battery uses a dual-cell series design (2S) – two 3.87V cells connected in series to deliver a system voltage of 7.74V, which enables the phone to achieve 50% charge in just 15 minutes and a full charge in under 50 minutes using the original 120W charger.
Why dual‑cell series design? Unlike conventional single-cell batteries, the 2S architecture allows higher voltage input, significantly reducing charging time while maintaining stable power output. The Oukitel WP30 Pro’s massive 5500mAh capacity (note: series connection does not add capacity, but each cell is 5500mAh) combined with 7.74V system voltage provides approximately 42.57Wh of energy – enough for 2+ days of heavy outdoor use, 35+ hours of talk time, or 20+ hours of video playback. Our replacement battery is built with Grade A cells, featuring multi-layer protection against overcharge, over-discharge, short circuit, and overheating. CE, RoHS, and UN38.3 certified for international safety compliance.
Compatibility & rugged note: This battery is specifically designed for the Oukitel WP30 Pro 5G rugged phone (check your model in Settings > About Phone). The WP30 Pro is rated IP68 (submersion), IP69K (high-pressure water jets), and MIL-STD-810H (drop, shock, vibration). Maintaining these seals after battery replacement requires professional expertise. We strongly recommend having this battery installed by a qualified repair technician who can reapply waterproof adhesive correctly. If your original battery is swollen, drains too quickly, or fails to hold a charge, this replacement will restore the original factory performance.
Battery care for long life: To maximize the lifespan of your new dual‑cell battery, keep the charge level between 20% and 80% for daily use. Avoid exposing the phone to extreme temperatures (below -10°C or above 45°C) during charging. Always use the original 120W charger and cable that came with your Oukitel WP30 Pro. If you notice any swelling, unusual heat, or performance issues, stop using the battery immediately and contact us for warranty support.

✅ 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.

|---|---|---|
| Warranty Period | 90 days from delivery | 15-30 days from order confirmation |
| When It Starts | 📦 Upon delivery | ⚠️ Upon order confirmation (even before you receive it) |
| Claims Handling | We do it directly — email us | Automated dispute system, seller dependent |
| After Window Expires | Still can contact us for support | No recourse, seller can ignore you |
🔋 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.
